Thanks Bill, my 3DL experience is similar, My 5 year old 3DL began delaminating in sheets towards the later part of the summer and is now being held together by sail tape. Interestingly all of the sailmakers I talked to said 5 years was the max life for a string sail.

I asked the Quantum rep about their pricing expecting to hear about better quality, shape, durability, etc. But only got an aw shucks I'm not sure why we are so much pricier.

I know Ullman does a bunch of J24 sails but they didn't seem to know the Class J30 sail is a 163%. The Neil Pryde rep said that they have made some J30 sails for boats in NE, so I'm hoping to hear something regarding their product from someone in that area.
