Thanks Rkfet

The reason I ask is that I paint it every year. Was thinking about not doing it this year - maybe just touch up.

When I paint the bottom, I cut the paint down with mineral spirits to about a 50/50 mixture. It is power washed at year end

I have never had any problems with algae build up but thought I would ask others on their preference and practices they have. I use my boat 1 - 2 times a week so it is not sitting at the dock growing algae. I have seen some boats that actual have vines dragging behind them because their boat sat idle for too long
