Interlux Antifouling Paint Calculator

Determining how much antifouling you will need is fairly simple. Here are two quick guides to help you purchase the correct amount:

1) Calculate the area needing paint. For a rough estimate of the area to be painted, multiply the length of your hull (LOA) by the beam and multiply by 0.85. (LOA x B x 0.85 = Area). Then divide the area by the coverage (see page 50) of the paint you've chosen to determine how many gallons per coat you will need, or

2) Refer to the reference chart below for a quick estimate:
