Re: installing flush hatc
Posted by Jim E on Oct 30, 2006
Derik, The extra layer of ply under the hatch has two functions:
It causes the hatch to hold the right curvature to match that of the deck. Having the hatch fit well is required for getting a good seal.
It makes the hatch stiffer and stronger. Imagine sitting on a large hatch during a 'cowboy' re-entry, or dropping a kayak on it during a rescue. Stiffness also helps with sealing.
