Hi All, Just added a page with the measurements for the early M15 mast, boom and standing rigging. The material was provided by George Morrison, M15 # 319. We need someone to measure their mast, boom and rigging on a newer M15. The information will provide useful to many in the future and invaluable to George so he can install the taller mast, with his new (late model) sails on his M15. When you get the numbers, please E-mail them to either myself or George and we'll transfer the numbers to a drawing by George and I'll post the taller mast measurements like we've done on the early version. AND, if we can get the folks who have M17's to do the same, I'll make a page for the 17's measurements as well. Thanks, Bill direct link to page: http://www.msogphotosite.com/M15mastmeasu.html
