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….

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…….

 

 

 

 

 

Adding security measures…..cameras ?

Since we have been using marinas during hurricane season it occurred to us that we might want to consider some additional security measures since most marinas are easily accessed by the general public and with that comes the risk of theft or other crime. We already have sturdy locks, cables and other security items on board.  I did some research and since we needed a system we could transport from location to location we decided to go with the Blink cameras.

The battery life was impressive (up to 2 years), they are wireless, easy to remove and install,  WiFi compatible, have an app that goes on your phone, tablet or both…they have in app adjustable motion sensors,  sensitivity, clip length adjustment ability and night vision.

These cameras can also operate off the hotspot on our phones while at anchor….although if we wanted to monitor them remotely we would have to leave one phone on board while we were gone. But they can add an extra sense of security at night if someone were to approach the boat as they camera will alert your phone almost immediately once the motion sensor is activated.

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…..

 

Some shots of the mostly finished floor

Attaching the veneer to the hatch plywood took a little time, some quality wood glue, and a few clamps……

 

The glue of champions…..

Titebond III Ultimate exterior waterproof wood glue with an applicator brush. All you have to do to clean the brush is let the glue dry and scrape it clean with your fingernail.

After it was secured …..

Let the staining begin……it ultimately took about 8 coats for the Light parts (the holly strips) of pecan colored stain and four coats on the teak parts of Gunstock to match the existing floor.

 

first coats…..

Then it was on to stain the section of floor that had already been replaced.

As you can see, there is a decent amount of difference in the old vs new colors……

This is as close as I felt I could get them to match…..

All we need now is some trim pieces to finish it off….. But that’s next time…..

Bike security while cruising….. or anywhere

Unfortunately, bike theft is a reality of life. While cruising we have used a steel cable security lock but recently I have seen how easily these are cut using pocket sized ratcheting cable cutters.

We decided to upgrade our bike security to the Kryptonite model 785.  They are relatively inexpensive at $30….and come with a theft protection plan that will replace your bike or motorcycle if the lock is defeated or cut.

here’s a link where you can get yours…..

 

 

 

 

If it wasn’t this ……it would be something else…..it’s like “This Old Boat”

So, after forty years or so, even the most sturdy among us often needs a little TLC and refurbishing.  I had noticed some softness in the aft cabin sole under the stairs and finally decided this was the season to see what was going on down there.
As you can see, at some point there was water penetration and some WDO’s  (some wood destroying organisms i.e. fungus, termites and other various destructive elements at work here at some point over the last four decades).  I went to work with an oscillating tool equipped with a cutting blade and a pry bar.

The port side bulkhead next to the stairs had some interior damage, so I stripped all of that out and treated it with Coppercoat to prevent any future growth or infestations. I was fortunate to be able to find the extent of the damage and replace it all.

The starboard bulkhead, that makes up part of the nav station, was lightly damaged along the bottom edge so, I removed that section, treated The remaining wood and replaced the damaged section.

New pressure treated wood was installed to support the subfloor…….no more WDO’s here !!!

I had to drive theses stainless steel lag bolts by hand…..quite a forearm workout

 

Then,  I ”double treated” the pressure treated wood with Coppercoat…..

 

I discovered that shiplap fit perfectly into the gap created where I had removed the damaged bulkhead section.

I had to hand trim and fit the new subfloor sections to fit the curve of the hull on the starboard side under the nav station.


Unfortunately, I couldn’t use pressure treated plywood because the epoxy used to attach the final teak and holly veneer wouldn’t adhere to that.  I was able to use exterior grade plywood. I liberally soaked the edges and undersides with Coopercoat however.

Cutting the same style hatch board to match the original wasn’t too difficult…..

A local friend made the matching width teak and holly veneer for me…..Now to experiment with some stain colors to match…..

Next time I’ll post some finished shots after the trim, stain, and urethane are applied….

Twilight Zone Part 2

This past season we had hoped the big news for the blog was going to be a trip to the Ragged Islands.  Since the lockdowns and protocols in the Bahamas were ever changing and at times contradictory we stayed put in Long Island for about eight weeks and then made the run back to Florida. It wasn’t a great season for photos as we were restricted to the boat for about 1/3 of the cruising season, but here’s what’s left of what we got …..

A Season From The Twilight Zone Part 1

So…..we left Florida just before New Years Eve, sacrificing our partying opportunities for a weather window to get down the coast and make a run for Bimini.  Our weather forecasting service wasn’t all that optimistic about the chances but we decided to go for it and see what happened.

We left Merritt Island and made it to Ft. Pierce that afternoon and anchored near a nice trawler named Diesel Duck (who we saw in the Bahamas much later in the season as they were anchored in George Town).

The next morning we departed Ft. Pierce and headed down the coast, trying to time our arrival for either an entry to Biscayne Bay if the weather was bad, or a turn toward Bimini the following morning.  As luck would have it, we were able to make the turn to Bimini just south of Miami and arrived there before 4pm for the outgoing tide so we could dock with some current against us and make it easier.

The below image is a screenshot of our track as we entered Bimini…..it was humorous that the dock hands didn’t mention that the channel had shifted about 100 yards to the south after hurricane Dorian.  If you take a close look at the green line, which was made as I was following our old track from the last few years you’ll notice we had to turn around and try again after we hit bottom!!!! The response on the radio was “oh ya mon we forgot to mention that”

 


We spent about two weeks in Bimini and I was able to enjoy my first ever bout if vertigo …..woof……don’t try that at home……I spent about four hours on a beach chair unable to even stand much less walk…..and then had two lighter bouts of it before it subsided and I haven’t had any issues since.

We helped out our friend Aaron at his bar The Hy Star Lounge for a few days and somewhat of a celebrity stopped by, if you are familiar with the Bravo TV show “Miami Million Dollar Listing”


That guy is apparently a multi millionaire and made it all on real estate in Miami after moving there from Ohio…….

After a couple of weeks in Bimini, as the weather cleared, we decided to make a run for the Exumas…….We made a jump for New Providence where we spent a night in West Bay and then made the ten hour jump to Norman’s Cay.  That was an adventure once we got there …..but more about that next time…..


I must have been hungry I already have my fork……
