Henry: 150% and a 110%. this is what i have on my M17. as the wind comes up M17 sails best with a 150% for as long as you can (and remain comfortable). my practice is to first reef the main and then go for a smaller headsail. for a 'working storm jib' something around 80% will do you well. dug up the following from a 2012 post by JudyB - [M17 headsail sizes based on Jerry's sailplan]:
80% with a luff of 19.25' 60% with a luff of 12'
two good folks to contact about headsail sizes, besides Jerry, are: JudyB with Hyde sails - www.judybsails.com or Harry with E/P sails - www.epsails.com for the two 'small' sails you have it would be best to go sailing in high wind to see how they perform. besides the dimensions you list you need to consider - * build of the sail (strong enough for high winds) * draft of the sail (to much draft for a high wind sail isn't good, you want 'flat' sails for high wind) * is the clue in the correct place for correctly trimming the sail on an M17. :: Dave Scobie :: M17 #375 SWEET PEA - www.m17-375.webs.com -------------------------------------------- On Tue, 2/25/14, Henry Rodriguez <heinzir@gmail.com> wrote: What hank-on headsails would you get for an M17 if you could only have two (in addition to a storm jib)? 110% and 130% ? 110% and 150% ? 130% and 150% ? 130% with reef and 170% nylon drifter? Other combinations? I like to sail in heavy air but often end up in very light stuff. In other words I need sails for all conditions, mostly on inland lakes with an occasional foray to Lake Michigan or Lake Superior. I can't afford to buy any right now but would like to know what to save up for. What size storm jib? I have a tanbark sail from a smaller boat that I think might work. It is 14'3" x 13'10" x 6'11", about 47 sq ft. I also have two real storm sails from Chiquita. One is tanbark, 14' x 11'6" x 6'2", about 36 sq ft. The other is white, 12' x 9' x 6', about 26 sq ft. Which would be most appropriate for a M17? -- Henry https://picasaweb.google.com/heinzir
