I have Ocean Kayak Prowler 13 as well. I look at it as a backpacking trip that you have to put stuff in dry bags to keep dry and bring along a cooler for beer.Pretty much what rechaps158 said. I did a 3 day trip at Union Lake and we camped on the mainland one night and then on a small island on the lake the other two nights. I just dry bagged anything I didn't want to get wet and packed everything as evenly as possible. I do bike tours more than backpacking so we pretty much packed the same except that we brought more food and drinks. If we were camping in rougher waters we would have to cut down on things for sure. Paddling with two full coolers is not the greatest or easiest.
We brought two coolers because Beer. If it weren't for the beer we would have saved like 40 pounds.
Looking at these pics makes me want to head back out there!
I know some of the "hard core" paddlers will poo-poo these, but we picked up some giant zip-loc bags a while back at Bass Pro shop.http://www.ziploc.com/Products/Pages/BigBags.aspx?SizeName=XLAn preferences on dry bags?
