JG, it's actually 9% not 6%, and that is to compare with the volume of the cockpit bellow the lowest coming.

From your measurements: 25x9.6X2.75x0.09= 55.6

You have a maximum allowable of 55.6 feet you can not exceed.

So you have to measure the volume of your cockpit, but from the top of the lowest coming to the cockpit floor,

height of lowest coming X Lenght X Width...that number has to be inferior to 55.6 feet

Joe, after posting my initial post, I tried to edit, because it was missing stuff and Sailnet crapped on me and I couldn't do it.

Now I edited it so it's clear.

George is right, it has to do with the maximum water allowed to be held in the cockpit
