Bottom Paint

[Doug Rutherford]

Will be painting the bottom of my boat this spring (first time for me) and need some recommendations as to best type. Sailing
the West Coast of BC. Vancouver.

I applied two coats of this to my sailboat in Feb 2018
Boat was kept in water , sailed from
Tampa to NYC August 2018 kept in water Barnegat bay nj until September 2019 when hauled . No growth anywhere except prop . Not sure how effective copper based ablative is where you are but I'm convinced! At about $100 a gallon two gallons was more than plenty for my 34 ft Sabre.

That's a pretty good price/performance ratio!

When buying "cheap" bottom paint, make sure you check the expiry date. Not saying that this is the case here by any means, just a general warning.

I'm a big fan of Pettit Trinidad SR.

One thing to really consider with any paint is compatibility. Even if you're not painting over an existing coat remember that at some point you will be re-painting and may mean the difference between completely stripping the bottom an painting versus a light sanding and re-paint if you can't find or don't have access to 'your brand'.

Oh and we use Interlux CSC micron for similar area (SE Alaska).

I've had good luck with Micron 66. Lasts 2.5 to 3 years, cruising the Inside Passage at 7 knots for 4.5 months, tied up in Poulsbo the rest of the year.

As with all of these "what bottom paint" ?s, ask your neighbors. Ususally varies with location.

It puzzles me why there isn't a bottom paint that works completely.

There are a lot of non organic natural things underwater that don't attract growth, some rocks for example, are clean and some are covered in slime and barnacles. What is it about the clean ones that resist growth ?

I'm sure the paint manufacturers (who have spent decades and tens of millions of dollars, if not more, in R&D) would love to know the answer to that as well.

Biologically speaking, unless the rock exudes a toxic substance or perhaps is so slick and vertical that nothing sticks to it (i.e., lacking rugosity), then it's going to attract growth. And the type of growth varies depending on water temp, upwelling, light intensity, water clarity, etc. That's why it matters what your neighbors have found to work best in your area. Other variables include how good the prep job was, how often you sail, how harsh the bottom is scrubbed and so forth. It's kinda like SSB installations. You do your due diligence and then you sprinkle some magic fairy dust and do a little dance to the sea gods and then hope it somehow just works for the best

Fun facts that NOAA didn't feel you needed to know:

The natural history and taxonomy of barnacles was a special interest of Charles Darwin.

Relative to body size, barnacles have the largest penis of any animal on earth--up to eight times body length...

Just so you know...

Just where can he put his prodigious member?
