1983 Oday 25 Genny: 135 or 150

[ddooher]

I am replacing the Genny on a 1983 Oday 25. It may be the original. I cannot tell if it is 135, 140 or 150. I'm guessing 135, which is plenty of sail. Do not have orginal specs. My understanding is I can figure it out by multiple measurements from Tack to Clew, to see where measurement increases (decreases). Neat project for my friend's 8th grader; and was wondering if anyone knew the answer off the bat.

Thanks, Stu. The diagram for the Luff Perpindicular (LP) is helpful.

To find the LP, put the end of the tape on the clew and have someone hold it there. Now pull the tape over the the luff, and move around until your find the SHORTEST measurement. That's your LP.
