Hmmmmm.... 15-20 cm too short....? That's like 5.9-7.8"
I can assure you the luff sleeve isn't going to ever "stretch"
Most North sails have the tack grommet set fairly high up in the sail
because they are intended to be used with a pulley hook, but the pulley
hook is only around 2-2.5" (5-6.3 cm) long.
I looked for more info on the Instinct but could not find anything.
I did find a set of spec's for the 2005 Instinct 5.3 on the Big Winds
website. Here's what they had to say:
Instinct 5.3 m 176 cm 454 cm
So, the luff length is 454 cm so you would need a 24 cm extension on a
430 mast. Should be no problem to simply lower the mast extension 15-20
cm so the extension is only 5-10 cm.
Also the simple graphic looks like the tack and foot does not have the
"traditional" North sails grommet set very high in the sail.
Are you using some extension under the 430 cm mast?
I'm pretty sure the 2005 Instinct was designed for the North Drop Shape
extendo mast, so the mast you have may not be very compatible.
Hope this helps,
