Square footage
Bottom paint makers suggest the following formula for figuring square footage BELOW the waterline: Boat length at waterline x max beam x .85. Obviously, a full keel boat would result in different number than a fin keel boat. I've used this formula on my H28.5 to estimate bottom paint and it works pretty well.
