How much antifouling paint do I need?

Use these following quick steps to calculate the amount of paint you need:

1. Work out the area to be painted using the appropriate formulation (below).
2. Divide the area by the coverage of the paint you’ve chosen to determine how many litres per coat you will need.
3. Multiply the litres per coat by the number of coats to give your total paint requirement.

Underwater area formulations

1) Full bodied craft

Full bodied craft

LWL x (B + D) = Underwater Area (m2)

2) Fin keeled racing craft

Fin keeled racing craft

0.50 x LWL x (B + D) = Underwater Area (m2)

3) Medium draft racing craft

Medium draft racing craft

0.75 x LWL x (B + D) = Underwater Area (m2)
