Don’t pay premium prices for premium sails. Here at the JSI we pride ourselves on producing a premium product at an affordable price. We are not a “cookie cutter” operation. We build all of our sails to order to ensure a proper fit and back them with our three year warranty. When comparing other sails to ours, make sure you are comparing “apples to apples”

Some questions to ask our competition: *

Are they using a High-Modulus premium sailcloth?

Do you offer extras at no additional charge i.e.; adjustable leech line, tell tales, sail bag, aluminum headboard?

Are your sails designed by an employee of the company ?

Can they walk out of their office into the sail loft?



Be wary of companies that do not require a measurement form! There are several key measurements that equate to proper fit and sail shape. It is impossible to make a perfect sail without the exact measurements for YOUR boat. You never know if a previous owner has changed something that would dramatically alter the proper shape of a sail.
