Jerry, As an M15 owner for a couple of months and 3 times out in the boat, if you were seeking owner input on where to allocate the space... Personally I think most of it should go to the cockpit. It would be nice to possibly be able to accomodate up to four adults with less of a 'squeeze'. BUT if you left just 2-3 inches more length for the VBerth that could make all the difference for 6' tall or taller sailors on overnights. Just my 2 cents worth. Neil Dorf Roseville CA
