Jist to add to conundrum
I had a new main made this year for my B38 , fully battened made by local sailmaker , he used a cloth called vectran , which is a very good dacron with a vectran thread weaved through it , has the long life of dacron and no stretch properties of vectran fibre , also lighter than equiv dacron , sets like a laminate sail , perfectly and will outlive a laminate sail by multiples of years , with no stretch , didnt cost any more than a best dacron sail either , very fast !!! too ,
This cloth was developed by north for superyachts and cost a fortune , now patent expired and available through other suppliers at cost mere mortals can afford, well worth looking into
b38 is one middle sandwidged by two boats with hi tech laminates , 3/4 tonner and sig 38
Vektran should not be confused with conventional polyester cloths - it's considerably stronger, more stable but slightly less UV resistance, and about twice the price of conventional polyester.
Hydranet is a UHDPE re-inforced cloth (Dyneema/Spectra), also woven by Polynant, but in Germany - it's at the outer edge of sailcloth technology and costs are similarly outré. Excellent for cruising/racing, being rather less short-lived than laminates - Personally I think its benefits over Vektran do not justify the price difference.
