I'm looking for 2 light weight, medium duty, sea kayaks that I can use in fair weather to paddle around protected bays in PWS. I need it light weight because I will be stowing it on the roof of my 24' ocean boat. And medium duty because I won't be crashing into river rocks and stuff. It needs to be no longer than 10'. And NOT a sit on top kayak. I'm just looking for a good direction to start looking or types to stay away from.
