I've toyed with the idea of building a cedar strip tandem for a couple of years now. There are a number of sites and resources available. With regard to boat design, I've had a half dozen possibilities on the board and am still uncertain which one to commit to. I haven't paddled a large number of boats but my favorite is still the old sawyer cruiser. I love the way it paddles, but fully loaded there just isn't enough free board for my comfort with any size rollers. I've thought about tweaking the cruisers basic hull design to make it more seaworthy for my taste. Ross Leidy has some great free design software at his 'blue heron kayaks' website. Has anyone here paddled a Swift Winisk and have any comments?
