I have used it on my dinghy
with good results for Maine
summer. Nothing collects on it. The Petit guy said it is the same formulation as their dinghy
(for hypalon and PVC) bottom paints and paint
for transducers. I am not sure this is much of a test, however, as my dinghy gets run at relatively high speed and regularly--it might be different for a sail boat in a slip. Also, I am convinced that different bottom paints work differently in different areas and also varies on how you use your boat. When I was in the tropics, I had great luck with Trinidad, because I dove the boat periodically and cleaned it--so a hard paint
that would stand up to scrubbing was best. Here in Maine
, you do not get in the water
unless you have to--everyone uses ablatives.
