Question

how often do you need to paint the bottom of a narrow boat.?

Answer 1

That depends upon how often you scratch it. If you cruise shallow canals, or sail over abandoned bikes, you get lots of scratches. As a general guide, better quality paint, and rubber type compounds will save time and money. But do paint it before the rust eats through!

Answer 2

Whenever it gets wet.
