I am ready to build the next boat, and think that I am ready for a full stripper, and really like the lines of the Guillemots.  What are the differences between the  "S" and the Play? I weigh 155 and am 5'8" and have a size 9 shoe. I am thinking that the "S" might be a bit tight. I have really been enjoying my WD 12 Hybrid, but at times, I find it a bit too beamy. I would consider the Sheerwater 16 Hybrid, but I really like the soft rounded sheer and chines of the Guillemots. Any thoughts?
