Designing a Self-Draining Boat: How to Determine Waterline and Deck Height?

[7177richard]

hi peoples... i have to design a small boat with a self draining deck. the boat has to be able to allow rain water to flow straight out above the water line. how do i work out where the waterline will be before i build the boat? and how do i calculate how high the deck should be? (depending on the weight of the load??)

any help will be greatly appreciated

Lookup buoyancy and the Archimedes' principle.

Basically, you can set the weight of the boat equal to the buoyancy force and you can solve for how high the water will reach on the boat.
