I is 10'? Is that some kind of a 3/8 fractional rig? What's your "J"
measurement? About 3'?

P is to long, my P is 27 feet (problem).
I is too long, my I is 10 feet (probably not a problem).

I have round slides (problem).

The tack offset is about right, boltrope for boom is right.

The main problem is it's too tall. Close but no banana!

Thanks, Thom, but it wouldn't fit and it's probably more worn out
than mine because you motor most of the time with the sail
flogging like Booby does.

Hey Neal,

I just thoughtof something. North is giving me 25% off the purchase
price ($368.00) What are your dimension of your main? They can't be
that
far off of mine. For $368 you have a huge improvement on your boat.
This
sail is only 14 years old and in good condition but would need a
tuck
taken in it.
Spec;= E=10' 4"
P=31'
Sail Area=160 Sq Ft
Two Reefs, plus a flatting reef ( Which I have been sailing the last
two
years
3/4" flat sail slides for mast, 3/8" bolt rope for boom. 4" tack off
set

It's yours for $368, if you're interested

Ole Thom
