I only recently found this thread. Enjoying it. To me, boat weight is a better metric for micro than length. It is a better guide to cost and general manageability. A 16-foot, 200 lb. boat has great advantages over an 11-foot, 2000 lb. boat! As noted in previous posts, many of the really short micros are both heavy and very slow! All other things equivalent, faster is better. 3000 miles across an ocean averaging 100 miles/day (3.62 knots or 4.167 mph x 24 hours) takes a month - much more reasonable than half that speed or slower! I also consider human power the most desirable auxiliary. I suppose that crossing oceans in minimum-length boats is OK as a stunt or for a record, but it doesn't really interest me. I want a boat that I can live and travel aboard for months or even years at a time. Realize that I'm a minimalist, happy to travel months at a time by bicycle (over 12,000 miles during one under 3-year period), generally self-contained with less than 35 lbs of gear, camping most nights. I also happily cruised for 3 months between Seattle and the N. end of Vancouver Island on my Marsh Duck, an 18' decked sailing canoe with micro cabin weighing about 185 lbs including all sailing and rowing gear and solar electric system for electronics. I slept aboard all but 3 nights (generally at anchor, occasionally pulled up on a beach or tied to a dock). I'm currently refining a design that I expect to build this summer: 15.75 feet long, 4-foot beam, Divinycell with fiberglass/carbon/epoxy skins; basic boat (shell) 55-70 lbs, maybe 100 including all sailing and rowing gear and a small solar electric system for electronics. Lightly loaded it should sail rather like a racing dinghy. With 300 lbs of gear and supplies properly stowed and me stretched out on the bottom of the very minimalist cabin the righting moment should be greater than empty with me hiked out. I expect to row for extended periods at 3 to 4 knots, depending on loading. I'll use it primarily for inland, island and coastal cruising (probably initially in the Salish Sea, then south down the Pacific Coast). I can easily imagine crossing oceans. The Skate 15 and the ROG 15 have similarities, but are higher, wider and much heavier. I find inspiration in Hannes Lindemann's 1956 crossing of the Atlantic in his 17-foot Klepper Arius II, and in Fredrick Fenger's 1907 Caribbean cruise on his 17-foot sailing canoe, Yakaboo. It seems to me that with modern materials, equipment and knowledge it should be possible to create better boats, make safer, more comfortable passages, and have lots of fun doing it.
