My father in law has a Wave up in wisconsin on a great chain of lakes. I've had to assemble it for the last 4 years and the hulls are a challenge to lift by yourself. While the boat would be easy to transport on a yakima or thule rack, getting them up there yourself is a challenge. Everything does break dowm into a managable load, but it's really a job for two.
That being said, I do drag the boat up and over two vertical feet of shore rocks and up a hill fully rigged with the saail down myself. It really has to do with hoisting heavy and awkward hulls over my head to put on my suburban's racks--not a fun solo job.
