From what I can tell, a sea kayak is different from a river kayak. The main difference seems to be that a nice sea kayak is much longer and built for speed than a river kayak. Sea kayaks also have large storage compartments in the fore and aft sections of the hull to allow the storage of food and other supplies if you’re doing an overnight sea kayak trip. Ok, that’s all the sea kayak speculation I have for now. I do know that when my friends Kris, Kristen and I did an extended sea kayak overnight island camping adventure in Palawan, we used the compartments to load up on supplies of My San brand graham crackers (best grahams in the Phils!), cans of tuna, mangoes, and some homemade bread that K&K cooked in their little home oven. Unfortunately our sea kayak adventure was to end with a rescue by a passing fishing boat (thank god), rather than a triumphant return to El Nido where we would paddle into the bay a little bit more tan, a little bit tired of grahams, and a whole lot ready for a celebratory pizza. Anyways, this gallery covers some of the highlights of our Palawan sea kayak adventure / mis-adventure depending on your outlook.
