Ah, you guys that live in the PNW, with your chilly water, have it made... rub on a little diaper cream and you're good to go?
Down here, in the land of swaying palm trees, warm sand, and bikinis, you can hear the critters in the water saying, "Ohhhh - fresh fiberglass! Mine! Mine! Mine!!" as you back the boat down the ramp. Without adequate bottom paint, you'll see growth and barnacles in less than two weeks.
We could probably use the diaper cream while we sit on an overturned bucket scrubbing/scraping the bottom (the boat bottom, that is) when we pull it out of the water. :wink:
Regular use of the boat really helps.
Bottom paint is your friend.
