The .55 is 55 % of the waterline length back from the fwd end of the WL. I incorrectly said I don't know about the "center of bouyancy" but what I meant was the CG; the center of gravity. The LCB is the longitudinal center of bouyance; fore-and-aft, in other words. Most well-designed sailboats have an LCB in the area of .55, which means 5% of the WL length aft of the center of the WL. I also approach this number in my racing canoes/kayaks and it seems to work out OK. OK? Jerry jerrymontgomery.org ----- Original Message ----- From: "Gary M.

Larry: For those of us ignorant of designations for LCB, etc. could you give us a little explanation? I.e., is LCB 0.55 of the length back from the bow or what? Thanks. --Gary Hyde N24 'Sailabration' M15 #235 'Vanilla'

Don't know about the center of bouyancy, but the LCB would be right around .55 as per all of Lyle's boats. Jerry jerrymontgomery.org

Hey All You Salty M-17ers,
Has anyone seen a diagram, drawing, cutaway ... whatever that shows the location of the Centers of Gravity and Buoyancy of the M-17 for various degrees of heel? I searched on the MSOG site and the Montgomery site and didn't see anything.
Thanks!
