Not only does the sudden temperature change create a higher apparent pressure, it also softens up the adhesives used to create the seal. http://www.guillemot-kayaks.com/gallery/MiscPhotos/IMG_1630 shows my Etrex after it died. The black rubber at the top of the picture creates the seal around the front and back half of the unit. On the upper portion you can see the inside and you can see some grayish spots. This is where the double-sided tape that forms the seal has separated from the rubber. I speculate this is from the heat of being on deck. The softened seal creates the leak and the sudden pressure change sucks the water in. It might not hurt to paint the unit white to keep it from heating up as much.
