Any suggestions on which of Nick Schade's boats to build? I am about 140 lbs, 5'7" tall and would like to kayak on lakes and the occassional calm river, only short day trips. I am just a beginner and have only rented a few different boats. I like kayaks that are both easy to maneuver around the shore but still fast and straight tracking. I really like the looks of the Guillemot, but am wondering if the Guillemot Play might be better for me. Thanks.
