No - it's not a class legal sail. You can buy the class logo as a sticker and put it on anything
Correct, it is not class legal and you can put it on anything, like a square top sail that out performs the stock sail and will most likely out last it. I got only 4 seasons out of my stock sail before it started to delaminate and tear along the luff. I sailed with the repair for another season while researching sails. Since Hobie refuses to update their sail design and materials (probabily due to the single class racing), I had to go aftermarket to get the performance I desired and leave the class racers in my wake.
