Is the average cost of a haul and 2 coats of paint is $1,000+ done by a yard... and now in NYS you most yard insist they do the bottom (enviro laws). If you do one hault out, every years and spend the rest on a diver you will have a faster bottom, less enviro impact more time in the water
and save money
or spend no more.
I know in the Northeast, hauling for winter is SOP, so maybe an annual bottom job is something you expect and for which you plan. But here on the West Coast
, we typically go two or three years between haulouts. We can do that because we will normally apply two coats of anti fouling
paint, which is the manufacturer's recommendation as well. A single coat of paint (be it hard or ablative) will not provide adequate anti fouling
protection for three years. So do the math; a thirty five foot boat hauling every three years for two coats of paint (at $2500 a pop) will run you about $7500 over the course of ten years. Applying a single coat every year or so (at $1700) will run you more than $10,000 over the same time span.
Then there is the environmental impact of frequent painting. When anti fouling paint is new and first splashed, the biocide leach rate "spikes" for about three months. If you paint every year, you are committing the spiked biocide leach rate to the water anually. If you paint only every two (or with proper care) every three years, that increased leach rate occurs less frequently.
And here on the West Coast
(at least in California), in-water hull cleaning
is a regular and necessary part of boat maintenance
. Here, bottom paint
only retards what is otherwise a pretty aggressive fouling growth progression. It is not a matter of, "well, since I have anti fouling paint, hull cleaning
is not necessary." And don't even consider not painting at all. No rational hull cleaning regimen can keep an unpainted hull clean.
