Hard coat is designed for scrubbing.
Don't assume that the fouling conditions and anti fouling paint
performance that you experience in Norway
are the same for boaters in other parts
of the world.
If your boat lives where the fouling conditions are moderate to high, you will absolutely need to clean the bottom, regardless of what kind of anti fouling paint
is on the hull
. And the more frequently you do it (within reason, of course) the better it will be for your bottom paint
, the boat's performance, the environment
and your wallet.
Ablative paints are no different than any other kind of paint; they need cleaning
too. Frequent, gentle cleanings will not harm the paint. Yes, some ablative paint will come off in the cleaning
process and that cannot be avoided. The trick is to not let the bottom become so foul that you can't use the most gentle scubber possible to remove the growth. This is true for any bottom paint
, ablative or otherwise. The OP does not say where he lives, but in this country, 3M "Doodlebug" pads are the scrubber of choice for professional hull
cleaners. Ideally, you will never need to use anything other than the white colored pad (which is the softest) but how heavily fouled your bottom is, is what will dictate which pad you use.
of thumb is; if you can't see the color of the bottom paint through the fouling, you've waited too long to clean it. Remember- frequent, gentle cleanings will make your paint last longer, improve your boat's performance (both under sail and power) and reduce fuel consumption
as well as copper and carbon emissions.
