Multiply the length of your boat's hull by its beam, then multiply again by 0.85. This formula provides the surface area, in square feet that needs to be painted. Then, check the coverage of the paint you've chosen. here
Here are some approximate amounts of paint needed for typical boats and sizes. Keep in mind that actual square footage and coverage varies by boat and bottom paint type. [links]
A simple way to determine the amount of bottom paint you need is to figure the approximate surface area (in square feet) of your hull below the waterline. Here’s an easy formula to use:
Length x Beam x .85
Because most antifouling paints have ablative or self-polishing properties, they wear away as the boat moves through the water, or as water moves beneath the boat. For this reason, you want to apply two coats in order to get sufficient protection from shell and weed fouling. It's also a good idea to apply an extra coat of paint to areas that see excessive wear, such as the leading edge of the keel, and at the waterline. Note that if you choose a hard modified epoxy paint (as opposed to an ablative paint), you only need to apply a single coat, as long as it covers completely. For specific film thicknesses per coat and recommended number of coats, refer to the manufacturer's directions on the product label.
Coverage calculations are calculated for mixed base and converter, reduced 25% and are based on a theoretical transfer of efficiency of 100%. Actual coverage rate obtained will vary according to equipment choice, application techniques, part size, and application environment.

Spray Application: 530 Sq. Feet at 1 mil (25 microns) dry film thickness; 210 SQ. Feet at recommended dry film thickness. Recommended Wet Film Thickness: 6-9 mils (150-225 Microns), Total of 2-3 Coats. Recommended Dry Film Thickness: 2-3 mils (50-75 Microns), Total of 2-3 Coats.
Gel Coat Theoretical Coverage: You should determine the square footage by multiplying the Length x Width of the surface that is going to be covered with gel coat. When you apply the recommended wet film of 18 mils you will get this coverage per coat:1 Quart = Approximately 12 square ft1 Gallon = Approximately 48 square ft.

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 of the paint you’ve chosen to determine how many quarts per coat you will need, or 2. Refer to the reference chart below for a quick estimate of how much antifouling paint is required for two coats: [links]
