Anyone know the dimensions from the portable head locker cabin sole to interior roof for the M15? Wondering if a West Marine "Go Anywhere Seat" could be used in the head locker sans porta-potti and v-berth center cushion similar to the arrangement used in Edey & Duff's Stonehorse Cutter The "Go Anywhere Seat" also works well in the cockpit. I have used them in my previous sailboats. In fact, coupled with a folding chair as a cushion, they can be very comfortable. I'm still trying to decide on M15 or M17, new vs. used. I like the interior and cockpit size of the M17, and I remember that some of my most memorable sailing was been in small boats, particularly my CD Typhoon and the family canoe I learned to sail in a few (actually 50 +/-) years ago. I enjoy thin-water sailing and feel like I might actually use the M15 more. Plan on doing a lot of singlehanded sailing, most day, but also hope to trailer sail around the US. Appreciate any info you can share. Thanks, Mark --------------------------------- Be a better sports nut! Let your teams follow you with Yahoo Mobile. Try it now.
