Antifoul Coverage Information

How much antifouling paint do I 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.

LWL = Waterline Length; B = Beam; D= Draft

For a fin keeled craft (right) the underwater Area = 0.50 x LWL x (B + D) m2
For a medium draft craft (left) the underwater Area = 0.75 x LWL x (B + D) m2
