Time to sand and bottom paint

[pelican]

High amounts of cuprous oxide retain their anti-fouling properties even when you keep the boat on the trailer. They're not real smooth, though. For smooth, you need an ablative paint, and need to repaint every year or two.

ablative paint - it wears away,constantly exposing a fresh surface - it retains it's protection well,if it's a multiseason ablative,like micron csc.it lasts,via "thickness",meaning,number of coats - in our area,it's 1 season percoat...i allways use ablative paint - due to the build up from single season paint...
