all rudders can stall. the 15 will have weather helm if overpowered (like all boats _should_ when overpowered). she communicates to the person holding the tiller when the sail(s) need to be reduced. i never felt the M15 has any more 'weather helm' characteristics than other craft. she is 'sporty' and light in weight so you really know how the boat is performing. the difference in 'feedback' is marked between the 15 and 17 - both sail similarly, but the 17 is more forgiving and provides less feedback (all relate to size, a few feet long and a wider, and heavier, at least 1200 pounds). i never took my 15 'to the edge'. there are other members that can discuss 'pucker moments'. dave scobie M17 #375 - SWEET PEA former M15 owner visit SWEET PEA's www-site - http://www.m17-375.webs.com --- On Sun, 7/18/10, Daniel Rich <danielgrich@gmail.com> wrote: I read the review from Small Craft Advisor about the M-15. Really nice review. One thing they say is that the rudder can stall. What does that mean? It is a long and thin rudder, so somebody apparently replaced theirs with a shorter broader one. Thoughts?
