Zinc….it’s not just a mineral for good eyesight

Once upon a time we began experiencing heavy anode wear.  It was quite a mystery….anodes are the sacrificial metals you attach to your boat that dissolve and save the important (and expensive) exposed underwater parts that invariably come in contact with either stray current, or current created by the exposure of certain dissimilar metals to saltwater or brackish water.  There is normally one on the propshaft and there can be others attached to different underwater metal fittings.

 

 

We were at a private dock with no other boats in the area, the shore power and boat shore power systems had been rewired just three years ago. The boat was in brackish water on the higher end of salinity for brackish. We were using prop zinc anodes very slowly until a few months prior when the zincs began to deteriorate faster and we took notice. We began losing about 60%-75% of a 1lb 6oz prop zinc anode in about 4-5 weeks. That works out to a loss of about 4 ounces per week. I didn’t think far enough ahead to weigh the remains of last few, but I will for the next one.

 

A few after this started I called and spoke with Bob, the corrosion expert with www.Boatzincs.com . Based on his recommendation I ordered a hang tuff hanging anode and installed it. I installed the clamp at the connection to the engine block for the ground wires. Sometimes they are shaped like fish, but the last few have just been cylindrical.

The starting weight for the new hanging anode was 2lbs 10 ounces.  After the first week the weight was 2lbs 9oz apparently that’s a normal loss for an area with moderate stray current.  After our first few anodes like this someone local must have had their dock or boat lift rewired because the zince wear diminished to almost zero. But these protected us until that was resolved.

 

So…be sure and use your zincs….and take your vitamins….

Boatyard Blues

Boat maintenance is one of those recurring things….some is monthly….some is quarterly….some is yearly…..and if you’re unlucky enough to own the boat when some of the items, that only need to be replaced every 20-40 years come along? …you have to do it ……and guess what ? This was that year for us ……we had two seacocks (valves that control water either coming into to or going out of the boat) that needed to be  replaced, and our depth sounder was dying a slow and painful death.

In addition, one of the lesser recognized hurricane hazards is from your own equipment.  During hurricane Ian, we were in a marina that experiences some decent swell from the south which tends to hit the beam of the boat and our secondary anchor bashed a hole in what is called our trail board, or as I call our “mustache” on our bow.

Fortunately,  we were about a month from a haul out for a bottom paint job.  So we decided to wait and have it fixed while were “on the hard”.

 

If you’re unfamiliar with the haul out procedure, there is a large framework on wheels that uses a system of hydraulics to lift boat out of the water and carry it into the yard via some enormous nylon straps.  You get the first view of how terrible your bottom looks …..(pun intended)

You also get to see what a horrendous job the prior boatyard did on your bottom paint…..Don’t ever use Cape Marine in Port Canaveral, Florida.

 


Next it’s the demolition phase……our depth sounder had stopped working in under 8’ of water (which is really when you need it the most) but still worked in 200’ of water???? That black collar is the inboard end of the depth sounder.

This is the outboard end of the transducer that is normally housed in a faring block that resembles a small canoe to avoid creating drag while underway.  It took and entire day to get the faring block cut off and to start the process of removing the actual transducer.  It only took 200 turns to get that thing out of the hull…..a quarter a turn at a time….while getting up and walking around a boat stand to complete each turn in the process.  As a bonus, it’s all from a squatting position.


Pretty, clean, painted and ready for the new installation……


Then it was on to the removal of the old and leaky seacocks (I know some of you are giggling every time you read “seacock”).

These are what they call “tapered barrel” seacocks that use a pair of nuts to maintain the pressure on a the edge of the barrel inside the body of the seacock to seal against water intrusion.  Our original seacocks are 43 years old and when treated well, and regularly maintained, they can last a whole lot longer.

The body is above and this is The barrel….

The inside and outside of the thru hull opening….

One of the new seacock backing boards….

A new seacock installed and finished….

We also needed to clean and refinish our running gear (prop, prop shaft, replace the anodes, and recoat with anti fouling paint.

step one sanding…..that takes a day…step two coating with zinc paint…another day ……..step three coating with water based anti fouling paint (the final Smurf  blue coat) that can take two or three days…..


We also replaced our prop shaft mounted line cutter to our prop shaft in case we pick up an abandoned line, net or a line from a crab or lobster trap.  Not fool proof, but makes life easier.

We had some damage to our boot stripe which we repaired also….and some scratches to the topside paint that happened during the hurricane.

While we are out of the water it’s a convenient time to compound and wax the hull….that’s a three day job …minimum….but she’s so pretty and shiny at the end…..thanks to Sherry and Dan Lambert, and Dave Uhles for the assistance.

Plus sanding, stripping, repainting and replacing anodes for our refrigeration “keel coolers” ….. if you’ve read the boat refrigeration entry, you know what those are already……

 

All in all, it took from October 11 to November 26th, and during that time I had the flu…or RSV or whatever they are calling it this year ….fun…..and hurricane Nicole made an appearance…….but it’s done now and we are back in the water awaiting the next trip…….

Watermaker Repairs….more of them

Purely for clarification purposes …..here’s a diagram of what our watermaker system is like….our current issue is the high pressure pump.

 

 

Watermaker diagram

 

 As you may, or may not recall, last year we had to replace our watermaker membranes.  Prior to that, I had to rebuild our low pressure pump and design a new cooling system.

 

A lot of people ask “How do you make drinking water from seawater?”

The answer is astonishingly simple, even though the design of the system is somewhat complicated. Here’s the secret…..

If you remember the membrane post, those membranes are some nifty little 40” long cylinders made by Dow Chemical, and when you place seawater under about 800psi, inside a housing, the water molecules are forced through the membranes and the salt molecules stay on the other side and can be discarded/flushed overboard.  Many islands in the Caribbean, and elsewhere, use industrial scale water makers, the membranes come in a large variety of sizes, for domestic fresh water production. Some of these units make thousands or tens of thousands of gallons per day. Our watermaker is capable of making 50 gallons per hour. Dow also makes versions for brackish water and other types of contaminated water.

Here’s what the membranes look like in the wild……(outside the housing)….

Our current issue was that our high pressure pump (circled in the above diagram in red) was leaking, despite a recent rebuild.  As it turns out, this pump ….(you can see the salt residue where it was leaking….)

 


is NOT designed for use with salt water…..which is kind of an important feature for a seawater to drinking water conversion system. This pump is designed for use in industrial fresh water pressure washing …..like in a car wash.

So, I had to research a new pump…..this one…..

The General Pump model WM4215

 

A little pro tip…..if you need a pump for any application always check with the online company Kleen-Rite….. (https://www.kleen-ritecorp.com) even people who work in the pump repair and supply industry have trouble figuring out how they get their prices so low…..but it’s an advantage for the DIY’ers……

I saved about $1,000 by ordering it through them. It required a little more phone time, talking to them and General Pump, the manufacturer, to get the configuration correct but it was totally worth it. General Pump even installed the electric clutch and pulley at no charge. https://www.generalpump.com

Now the issue is getting a different pump to mount in the same place as the old pump.  I’ve been working on fabricating a bracket that will adapt the old mount to the new pump…….but that’s for next time…..

 

What to Expect When You’re Expecting to Arrive in Cuba…Part 3 of the Cuba Series

 

So, there’s been a few changes to the U.S. administrative aspects for visiting Cuba. That doesn’t mean the visits are completely over. People from the US have been visiting Cuba for decades before some restrictions were eased in 2010. The important thing to remember is that nothing lasts forever. You could, and still can in some instances, visit Cuba without supporting the Cuban government. There has been a blanket policy instituted prohibiting private vessels and aircraft from visiting but this has yet to be tested. It seems a bit discriminatory, to me, to allow guided tours by companies and yet prevent private citizens from visiting for the same licensed purposes.

 

 

 

 

 

Based on my conversations with the citizenry, the Cuban people are weary of their government running every aspect of their lives but live in fear of being jailed for speaking their minds.  Visits to Cuba and the expenditure of foreign dollars at places controlled by the government (i.e. Cruise ship areas and many of the tourist traps in downtown Havana) only perpetuate the system that oppresses its own people and supports similar systems elsewhere.  Cruise ship fees go directly to the government and military.  Almost all the shops and attractions around the cruise ship ports are government controlled.  We were very cautious to only visit private businesses, which are only the very small family run style and the individual owners keeps the proceeds. Marina Hemingway is controlled by a private group and is the only marina where you can currently clear in when coming from the US.

Cuba is the only country I have ever visited, where, despite the constant touting of their healthcare system by some, you continually meet adults with completely treatable conditions which they are not “permitted” to have surgery or other remedies to correct.  The most notable was an otherwise perfectly health young bartender who had suffered from frequent infections of his tonsils since he was a small child.  He was frequently unable to speak for a week or more.  The only treatment he could obtain was a constant supply of antibiotics which will eventually lead to bacterial resistance and a host of other side effects. He was also not allowed to leave the country for surgery.

I’ve read a lot of complaints about the tightening of the visitation regulations.  Most seem rather selfish and short sighted. Imagine if the employees at any business were denigrated, oppressed, threatened, denied healthcare, and generally mistreated by the management ? Would you still patronize them and line the pockets of their oppressors? If Europeans and Canadians were allowed to go, and went, at times supporting such a system, would you use that as an excuse to visit through that form of tourism anyway ?

US Travelers can still visit Cuba, subject to specific conditions:

Family visits
Official U.S. government business
Journalistic activity–you must be employed full time by a recognized media outlet….unfortunately bloggers don’t qualify
Professional research and meetings
Educational activities (like those from U.S. academic institutions and secondary schools)
Religious activities
Support for the Cuban people—this will hopefully be the license that allows private vessels to visit again.
Humanitarian projects

If this program doesn’t work out we will have to wait till the tide turns and we can more easily visit Cuba again (without supporting this current Cuban government) let’s still be ready……

You’ve done all your research, you have the USCG permit email in your hot little hands, the boat is ready to go and there is a weather window approaching right on cue.  Why are you so nervous then?

Over the decades there has been a lot of misinformation floating around about Cuba, some even correct information attributed to the incorrect source or cause.  Some people believe it is crime ridden, dirty and unsafe. I have always judged places I visit by the character of the people and not the spit and polish state of their buildings and streets.  By this metric, Cuba could not be a better place to visit.  It certainly has infrastructure problems. Sidewalks are broken and usually poorly maintained, if still usable.  Roads are potholed, some are dirt, some (most) have horse drawn wagons on them, even the interstate.  The people are kind, honest and humble.  Cuba is more than Havana, as the US is more than NYC.  Some think Cuba must be like any American Cuban neighborhood they may have visited.  It seems that Cuban/American culture has become so commingled and diluted by American culture that it has become unique. The lack of similarities were surprising.

Back to arrival preparations…..be sure and take a stack of $5 bills for tips, I took about $100 in fives.  You will meet Marina attendants and other employees who will expect small gratuities.  Don’t change any money until after you are fully checked in and don’t go to the hotel or the bank when you are ready to change it.

If you like to trade things, take some MLB hats or shirts, some American beer, some bourbon or other American products that aren’t imported to Cuba.  They make great gifts when someone really helps you out or just to trade and save a few bucks.  We traded a case of Budweiser we bought for $15 stateside for a case of Cristal Cuban beer which was $24 a case. We gave away hats and MLB shirts to people we made friends with around the marina. That didn’t hurt when it came time to stock up on rum, coffee and cigars as we were pointed to the best sources.

As I previously mentioned, the entrance to Hemingway Marina is tricky and exposed to North winds, so you’ll have to time your arrival appropriately.  The channel is a bit narrow and there was a sunken boat on the east side of the channel in about 15′ of water when we were there.  If it’s your first time it will look a little confusing as you come into the inlet.  The markers are on poles rather than the more traditional buoy.  That makes them hard to see from a distance to be sure you are lined up. The last green mark before the turn to the customs dock (the dock, actually just a wall, is painted blue and I marked it with a blue line in the image below.) the last green mark is actually on shore and obstructed by some large growth.  The seawall on your port side is the edge of the channel, but I still wouldn’t cut it too close. The channel appears to drastically narrow and in truth the last red mark does narrow it slightly but it’s not as bad as it looks. It would have greatly reduced the stress had I known the last green was on the corner of the land by the Customs dock, rather than just being confused about where it might be lurking.

 

Once you round the corner and tie up on your port side, the Customs officials, who were all much younger (early 20’s) and friendlier than we anticipated, come aboard.  A Nurse comes aboard with Customs for a few minutes to take temperatures and generally check the crew for communicable diseases.  The process was quick and the search was very, very minimal.  The customs officers won’t accept or expect a tip, although some might accept the offer of some coffee or a soda.

Keep in mind these canals were dug out and poured in the 40’s or 50’s the concrete must have escaped from the forms during pouring and there are some large extensions that extend into the canals by 5-6′ in places at depths of 3-5′. Stay as close to the center of the canal as you can until you’re ready to tie up.

If you can, it’s a good idea when you make your reservations to request the first canal and the berths along that wall are numbered in the 100 range.  We were in slip 124.  The restrooms and a small snack bar are located where you make the turn into that canal, so wifi and restrooms will be convenient.

Speaking of wifi….you have to purchase wifi cards, similar to the old prepaid phone cards in the US.  You can get the cards at the snack bar, the Chinese restaurant, the Yacht Club or the Mexican restaurant.  Then you go to a place with wifi access, the snack bar, the Chinese restaurant, which is very good, or the Yacht Club and log in.  You get an hour for $1.50CUC.

As you approach the wall in the canal, the dockmaster will probably be there to meet you.   The dockmaster will hint around for a tip. I found that giving out a few $5 tips when appropriate makes later interactions much easier and the people you might need help or guidance from are obviously much more willing to help.   The marina electrician has to plug your boat in and it’s a good idea to give him a small tip because you will have power outages and he will be the one fixing the power pedestal.

Next the agriculture officer will come around to inspect your food stores and make sure you don’t have any risky vegetables or meat.  A Doctor from the health ministry will come aboard to verify your holding tank is closed off from discharge (they just ask but don’t inspect).  After the paperwork is done both of these agents will say “we would appreciate a small tip if you’d like to give one but it isn’t necessary”, we tipped them both and they checked in on us three times during our visit to make sure we didn’t need anything.

After that you are all checked in and ready to see Cuba !!!

The store, marked as the “Ship’s Chandlery” on the satellite image is the best place to change money.  You can get .9 CUC for each dollar rather than .87 and paying any other penalties and if you have Cuban CUC’s left at the end, Jose the store manager, will buy them back. Jose is also a great resource for meeting other people who sell rum, cigars, coffee, souvenirs and conduct tours at much cheaper prices than the stores and other organizations.  Plus you’ll know your money is going to the person and not the government.

There are two currencies in Cuba.  The CUP, the peso, is for Cubans.  The CUC is the tourist currency.  One CUC is equal to 24CUP.  Tourists are not legally allowed to have or exchange in pesos.  All businesses accept both.  Some, that charge in pesos will charge tourists in CUC one for one.  Most will adjust the exchange rate and you can eat and drink very inexpensively.  One afternoon three of us had lunch and beers for about $8.

Next time we get around Cuba and buy some goodies……

 

So, you got approved for Cuba, now what ? Part II of the Cuba series…plus some pics

 

 

So, the Coast Guard sent you the approval email…..how exciting !!! But now what ???

Don’t forget the clock is ticking and you probably only have a week, or less, before your approved departure date arrives.

 

Our courtesy flag flying !!

 

Hopefully, by the time the email arrives you will already have a Quarantine flag, a Cuban courtesy flag, a cruising guide or two, (I had read our cruising guide once or twice before we even applied) and charts. If not, you can order them here…..

 

Mike taking down our “Q” flag after we cleared in.

 

In addition, you should have an appropriate supply of spare parts, provisions and done some sort of shakedown trip to bebug any known or unknown issues you might have. You can buy food in Cuba but it’s more fun to explore and try out the local spots than to have to shop, parts would be VERY difficult….parts from the US would be almost impossible.

First things first…..start checking the weather…..this will be the most limiting factor for your passage and may force you to adjust your departure date with the USCG, so watch it closely. Before we left for Cuba we met a nice gentleman in a local Marathon bar. We overheard him say he owned a Hunter 35 (which was the same model Mike previously owned) so a boat conversation promptly erupted. He asked where we here headed and we said “Hopefully Cuba!!” He said he planned to leave for Cuba and keep going south as his boat was his only possession and he had no family to keep him in the states. Since he didn’t plan on returning he wasn’t going to bother getting a permit from the Coast Guard. He planned to leave near the end of March and we told him we would see him there.

Once we arrived in Cuba there was an extended period of moderately heavy to heavy North wind. It was so bad that the St. Pete to Havana race was almost cancelled. They delayed the start of the race by a day and a record was set in the spinnaker class for completion of the trip. That boat shaved about seven hours off the old record if that gives you any idea what the winds were like.

Once the North winds exceed 15 knots for a certain amount of time the Hemingway Marina stops allowing boats to enter or exit as it becomes quite hazardous. The entry channel is bordered by shallow rocks on either side and between the countercurrents from the Gulfstream (which at the time was very close to the north shore of Cuba) and the wind it can be difficult to avoid broaching (being turned sideways from wind and waves on the stern) and crashing into the rocks. Plus the North shore of Cuba is mostly Reef, rocks and shoals, then add to that, the depth goes from 1000′ to about 50′ in less than half a mile and it can be very dicey.

After the St. Pete racers arrived and departed the North winds again increased. We heard a story about a sailboat that had apparently exited the Gulfstream to the east of the marina channel and had attempted to work it’s way back West along the shoreline to the channel. The winds had again become pretty heavy, the swells out of the North were still very strong, the boat was unable to sail or power away and the boat was pushed up onto the Reef. Upon returning to Marathon in the Florida Keys we learned that it was the man we had met in the bar just before we left. His boat had been trapped on the Reef for a few days and then a series of heavier swells had pushed it into a deeper pocket between the outer and the inner Reef. Unfortunately, there isn’t a channel or passage out of this area so his boat was damaged and then trapped in a pocket of deep water inside the two Reef areas. We haven’t heard anymore updates but it seems his boat will be a complete loss. Even if he had insurance, American based insurance companies offer no coverage in Cuba. Until March of 2019, two companies had offered special riders for Cuba coverage but they ceased to offer that citing “declining diplomatic relations”. Just before we departed Cuba, a second boat, a catamaran enroute to Key West from Mexico, was forced into Havana harbor by rough seas and high winds and later relocated to Marina Hemingway once the winds subsided. So, it’s weather, weather, weather….and make sure your engine and drivetrain are up to the challenge should you end up with a Lee shore and need the power to make a getaway.

You hear a lot of odd stories about what to take to Cuba if you’re interested in giving gifts away. We have heard people say that “hygiene products” were popular gifts as they are difficult to obtain in Cuba….or some sort of perfumes or other toiletries for women were in demand……..we didn’t see, or hear of, that. Some of those stories also came with sort of an underlying, unseemly motive for those types of “gifts”, so avoid that.

Cuba has changed quite a bit. Cellphones and social media are common. Personal items may be slightly more expensive but are readily available. Wifi, while usually available at parks or restaurants by the hour, isn’t overly common at residences. Even at a park or other location with wifi you have to buy a wifi card and then it’s $1.50 CUC (the tourist currency) for an hour of usage. Funny side note…most Cubans pronounce it “wee-fee” so the traditional pronunciation can lead to some confused looks.

I asked a few people we befriended if there were any items that we, as Americans, might take for granted that were difficult to obtain in Cuba today and they said no. What we did find was that American products that don’t get imported to Cuba are interesting as a novelty. We took a few extra bottles of bourbon which we gave as gifts to some people, a case of Budweiser we traded for a case of Cristal beer and we had some baseball shirts and extra hats on board that we gave away to some of the people we met who had kids involved in baseball. They were very grateful for the gifts as they love American sports teams in Cuba.

this one’s for Barb Lienhard ….Happy Birthday !!!

 

There’s also a lot of talk about what kind of currency to take with you. People often exchange US dollars for Euros in the states to avoid some of the penalties charged at official outlets when exchanging US currency. Save your time and just take US dollars. You can tip in USD until you get your exchange finished. Take plenty of $5’s for the tips. Customs and Immigration won’t ask for a tip, or expect one, but the dockmaster, the electrician (who has to connect your shorepower), the agriculture officer and the health inspector will all say “the fee is $X and if you’d like to include a gift we would appreciate it”. Plenty of people laugh at them and give nothing but the goodwill was well worth the small price. We got plenty of visits from people asking if we wanted or needed anything and we saved about $300 on the stuff we bought to bring back (rum and cigars). In the next post we will tell you where to go to get the best exchange rates, pay 0 penalty AND get a better rate. Plus if you go to the right spots to eat you’ll be paying the lesser amount for food in pesos which is $1USD to $25CUP (the locals currency) as opposed to $.90 USD to $1CUC. Three of us had lunch and beers one day at a local place for $8USD.

What about the language barrier? English is taught in Cuban schools, but like any second language taught anywhere, if it goes unused it is lost.  A lot of Cubans in the marina area speak English very well.  Download an English to Spanish dictionary to your phone, buy a copy of Spanish for Cruisers and learn some key phrases.  Almost every menu is in Spanish….it helps to know what Cerdo, a chuleta and a pescadore are and how to get directions helps……We made some cheat sheets to review and assist the crew.  I had a few years of Spanish in high school and fortunately a lot of it stuck with me…comprehension is easier and after a few days I can carry out  a decent conversation.

Last, but not least, is route planning. Hopefully, you’ll have moderate east or west winds, we had light south winds, in between bouts of heavy north winds, so we ended up motoring the whole way. If you have the time, or the inclination, I would go as far West as you can before leaving the Keys. If your weather window is big enough, go to Dry Tortugas for a day or two. There’s a blog post for Dry Tortugas for any newbies.  That way you will already have made some distance to the west and then join the flow of the Gulfstream, rather than fighting it, and make your final part of the ride smoother and faster. When we left, we left from Key West and we planned to turn at N24.95.840/W082.34.186 to a course of 177 degrees T and then end up about 6 miles east of the Marina entrance, turning back along the coast outside of the Gulfstream. Once we got out there the Gulfstream was further south so we got an extra ten miles West before turning south and were able to head straight for the marina entrance avoiding the risks of the north shore arrival and subsequent westerly backtrack. The Gulfstream was VERY close to the north coast of Cuba at that time. It was about a 25 hour crossing.

Next time…..how to get the “hook up” in Cuba for currency exchange, tours, rum, cigars and more…….

It just raises and lowers the anchor….how complex can it be ????

It recently occurred to me that our windlass could probably use some attention.  After all, it has served us well for a few seasons and hasn’t received any TLC. Our prior boat was much smaller and didn’t have a windlass. Since I didn’t have any experience with any sort of windlass maintenance, I turned to YouTube.  Imtra, the company that manufacters the Lofrans Tigres Windlass we have, has a channel with a detailed six step maintenance tutorial.  All seven videos were a total of about 30 minutes….easy peasy, right ?

It seemed simple enough, so the next day I dove into the disassembly, cleaning and regreasing. In the far left side of the diagram, on the end, you can see the Circlips, which are small circular washer type safety stops to prevent an item on a threaded shaft from falling off if you loosen it too much or it vibrates loose. Those were missing, so I found and ordered some from Grainger.  It seemed that the end of the driveshaft had been damaged at some point and the slot for the clips was bent closed……40 minutes of filing later, the groove was fixed.

So, working our way inward, once the clutch release is spun off you can remove the outer clutch cone, lower the chain stripper out of the way by removing the aft mounting bolt, remove the chain gypsy and the inner clutch cone. Our inner clutch cone was deformed and jammed on the driveshaft.

So, our inner clutch cone wouldn’t come off.  In the video it slipped right off for cleaning, greasing and replacement, not so much in the real world.  At some point in the history of our windlass it must have had a lot of stress on the chain without a snubber line to absorb the force. It was bent and slightly split where the keystock fits into the driveshaft.  The stainless steel shaft was also slightly bulged, deformed and the keystock was bent.  So…out comes the Dremel….90 minutes of careful cutting and the clutch cone was off…..plus ordering a new one for $74 and waiting for delivery…..plus a new gasket for the motor housing $22….

I found a great new source for parts…. https://www.pleasureboatmarine.com they were quick to respond and the parts arrived in two days.

Once the new inner clutch cone arrived I had to file the driveshaft to remove the bulges.  That was another hour of fitting the bronze cone, and filing and fitting, since bronze is softer than stainless it made yellow marks on the shaft where it made contact which made it easier to know where to file.

After that was greased and installed the rest went back together pretty easily with the addition of the safety clips on the driveshaft.

Next, I removed the motor housing cover.  This is held in place by two threaded rods that fit into the main body of the windlass secured by acorn, or cap nuts on the outside of the cover.  Our cover however, had a bead of caulk around the edge making it extra difficult to remove….so add forty minutes to the process…….

It appeared this caulk was necessary because the nitrile cord gasket had been installed backward and the raised edge was in the groove of the cover rather than facing outward toward the main body of the unit.  This removal process was made slightly more difficult by the proximity of the standing rigging for the staysail.  I had to loosen the acorn nuts, pry the cover loose, then remove the rods and then take the cover off at an angle and use a rubber mallet to “encourage” it.

Since the housing is aluminum and the bolts and acorn nuts are stainless the cover should have plastic “Delrin” washers to keep the metals from touching as they will interact and cause corrosion.  Those washers were also missing.

The motor housing was in good shape, the wiring was run properly under the motor and the terminals were clean and secure.   I cleaned the motor and applied a light coat of oil to inhibit corrosion.

 

Once it was reassembled, I tested the rope rode drum side (far right in the diagram), the manual override (where the vertical handle is) and we loaded our new, 250′ of anchor chain into the boat.

 

need one ?

The 30 minute videos turned into about 4 hours of actual labor and a few days of waiting for parts…boat life !!!

As an added bonus, our windlass remote control has stopped functioning in reverse mode so that’s next on the list…..

Let’s see who knows about Anodes….

A season at the dock…..Part I

We were hoping to make a late December getaway to the Bahamas since November was preempted by some return trips to visit and support family,  but on December 26th I was paid a visit by the kidney stone fairy.  I’m very glad we weren’t in the Bahamas as this was my first time dealing with one of these.  On the pain scale of one to ten I’d give that experience a 12…..I was told by the doctor that I had two more waiting in the wings so we thought it might be a good idea to take this opportunity to fix some things that we had been putting off while we were staying put for a while.

We had a few projects……..Our watermaker had stopped working in the Bahamas, and that required diagnosis and repair…..we had some wood work that needed repair from some very old water damage,……our alternator needed a rebuild and realignment……the adjacent engine driven, high pressure watermaker pump also needed to be realigned……our refrigerator and freezer compressor had originally been wired in the same circuit which I thought was interfering with the performance when both units tried to start up at the same time,….. our wifi range extender was on the fritz,…… our new outboard was due for it’s ten hour service and our backup, new to us, outboard needed some work as well, and our masthead wind instruments (which supply the wind speed and direction to our instruments) stopped sending data to our cockpit display for some reason and finally our refrigerator evaporator plate needed to be replaced. Keep in mind these projects were tempered by trips to the beach, happy hours and visiting friends !!!!

First a quick tutorial on watermaker function.  We take in seawater and filter it to remove any large contaminants.  Then the water is pressurized using a “low pressure” pump at about 17psi.  That pump maintains the pressure to the high pressure pump which operates at hundreds of pounds of pressure.  The water then travels through two tubular membranes (filters).  The seawater is highly pressurized and travels along the outside of the membrane and the freshwater is pushed through to the inside of the membrane “cylinder”.  That freshwater goes to our tanks and the remaining briny seawater goes overboard. Sounds simple right ? Here’s a diagram ……

Our watermaker was a two fold issue.  Our low pressure pump, which feeds the high pressure pump wasn’t moving any water.  It is an intermittent duty (i.e. 30 minutes on and 30 minutes off) pump and required a cooling coil to keep the temperature down and extend the duty cycle.  Unfortunately, the cooling coil couldn’t make 100% contact with the motor so it suffered from some efficiency issues.

I had initially assumed that the motor was burned up.  I removed the pump and was about to order a new one.  I had hoped there had been some advancement in  pump design and we could get a continuous duty pump, but apparently there haven’t been any advancements in this type of pump design.  I thought we were destined to replace the pump for $395.  As I was taking the pump to the trash, I decided to try something and I attached the leads to the battery in our van and the pump ran !! So, I found a local pump repair shop and got it rebuilt for $65…although, it took over two weeks to get the parts.

Once the pump was rebuilt I began to investigate other ways to cool the pump and extend the duty cycle.  I discovered that Shur Flo pumps makes a 5″ heat sink that fits the motors on a variety of other manufacturers pumps.  I get the feeling the motors are all made by the same company and relabeled for the “manufacturers”.  I consulted with a friend who was an aerospace engineer for ideas in cooling the pump motor and he recommended “Thermal Grease” under the heat sink.  This makes the contact between the sink and the motor housing 100% by removing air gaps and the grease has metal particles in it to transmit heat more efficiently.

I added a 138cfm cooling fan like you’d have on a large computer and fabricated a support from a PVC bus hub and a rubber reducer coupling and ended up with this …..we flushed the system and the motor was as cool as a cucumber !!!

 

The “woodwork” turned into tearing out 60% of our port settee and replacing the entire seat and a small section of the outboard bulkhead that separates the storage area.  I used marine grade plywood and treated it with Copper Coat which is a 9% copper solution that prevents future mold, mildew, rot and insect infestation.  I also increased the size of the access hatches so we can store dive tanks under the settee.  The biggest challenge was matching the shape of the board that was glassed into that area which would not come out in one piece…or even six !!  A lot of the outer edge had to be ground out of the fiberglass.  I took this opportunity to run some extra 0 gauge wire forward for the addition of some  electrical items down the road. I was tempted to remove the washing machine during this process, but decided we could do that later.

Next time…alternator….masthead instruments…..pump alignment….fridge/freezer…..etc….etc….etc

An interesting new product we discovered….”Sugru”

On our boat we have a lot of essential electronic equipment.  Some of these devices have remote handsets you can use to control and/or monitor the device like the Autopilot, VHF radio or windlass.  These handsets have coiled, rubber coated cables that run from the control head to the plug.

Recently, our autopilot control head cable began to deteriorate.  This was pretty concerning since our autopilot was manufactured by a European company called “Cetrek” and they have been out of business for a few years.  Since a new autopilot would be around $1500 for just the equipment, we were tying to come up with a way to repair this, and future, cables.

I found a product online called “Sugru” and it is described as a “moldable glue”.  It is billed as being waterproof (including salt water), UV resistant, flexible, electrically insulating, heat/cold resistant and shock / vibration resistant.  This was readily available on Amazon so I ordered a multi pack.  It comes in various colors but for our purposes black matches our cords.

 

I applied the first section as a test and in 24 hours it was fully cured and seemed to live up to it’s sales pitch.  I plan to cover the rest of the deteriorating cord and we will post an update in a few months when we can fully evaluate the wear it stands up to during our travels. I also suspect that Sugru will be a good replacement for caulking around spaces like those around our chainplate through hull openings on the deck combing which need to be recaulked every few years or they leak.  This may be a permanent fix for that issue!!!  It was a great improvement over the electrical tape wrapping I was trying to use on the cord. It was easy to use and not messy at all.
