That is a cool looking boat!
worth his salt
will come down to your boat and take the measurements himself. He stands to make a chunk of change if you are buying
a new suit of sails.
If you are buying
used sails, he is obviously going to be less interested in spending his time measuring your boat. Perhaps you could offer to pay him?
If not, you should be able to figure out the IPJE measurements with a tape and some spare time. Finding used sails is not always easy. Remember, they are for sale
for a reason, and it is up to you to decipher what that reason is! They may be blown out, have poor repairs
, lack a proper cut.
A lot of these problems can be solved
by having the sail worked on, but that is more $$$$$.
If you are not concerned about performance, then I guess you will be totally satisfied with used sails. I know that if I were to buy sails for my boat, I would probably end up going with new ones. Even though they cost twice as much, a sail that is just wrong has very little value....
Pragmatically, if it makes you happy to have your boat move, then go for it.
If it makes you happy to have your boat perfect, don't.
I don't know how I became one of those guys that strives for perfect sail trim. It probably started when my grandpa gave me a 5 pound tome on sail trim.
