I have built two S&G kayaks by Eric Shade, the Widgeon, that are 14 ft long and 24" wide. I am contemplating on building a narrower strip kayak for learning to roll. I am 5'8" and 140Lb. Why do most people choose such long (17-18ft) kayaks? I understand the advantages of higher hull speeds and higher volumes to carry gears, but don't plan on doing any racing or over-night camping, just paddling in local lakes and Long Island Sound on calmer days. I had drawn up a few 14x20 kayaks with Ross Leidy's Kayakfoundry, with design displacements of around 185Lb with 3.5" draft. Before I cut wood, any suggestions or advice?

Thanks, from Guilford, CT.
