Hi Pete, I have no less than (6) different set of spec's
For the Ranger 26. Your best bet will be to measure your hoist, then measure the distance from the tack, back to the mast=J measurement.Here's spec's on 1 of 6 we have on file:"I"=33.00 "J"=11.50 "P"=26.40 "E"=10.00If this is your boat, your theoretical max luff would be 34.9ft., if you're using hanked sails. You'd probably look in the range of 34ish for hoist, and a foot of around 17' if you want a 150.Give me a call if you need further explanation. Minneysyachtsurplus.com is one place to look for used sails.We would love to build you a new one, of course!There was a tall rig, regular, what they called "short mast", as well as 26-1, 26-2 and 26-3
