Thanks for the link to that calculator! I used the same math to measure my sails but had to do it with pencil and paper. This is really handy. Henry Monita Chiquita On Sat, Oct 22, 2016 at 2:04 PM, John Schinnerer <john@eco-living.net> wrote:
Tidying up my sails, finally doing some measuring...
My "small" jib is not the 109% standard or working M17 jib, it's quite a bit smaller. Here's one calculator I found: http://sailingfortuitous.com/apps/jibcalc.html
This and other similar formulas found online put it at about 81-82% (luff 189", leach 160", foot 76"). In between a working jib and a true (like 60-65%) storm jib.
Also played with the outhaul method shown in that video I posted recently. Really a good idea AFAICT. Works as clew strap and outhaul both; automagically balances the angle of pull on the clew.
And, makes it much easier to move that same outhaul line to a different reef grommet - no need to tie or untie any knots on flapping sail in bouncing boat. Just loose the outhaul, pull out of current grommet & block, route back through new grommet & block & make fast. With a boltrope or slug footed sail of course. This would be a Very Bad Idea on a loose-footed main...!
