not a bit like dacron --- fits their description of a North 3DL Marathon covered with Taffetta Film ... now delaminating ... still works ok I think, but that film is going to start ripping away anyday now.... and puckers the surface.
out today SW 12-15 on shore, ~80 degrees, sunny, 40 min spin run with our buddy boat Shock! a Wavelength 30 ...
Now have on a two year old North 7.8 oz. NSP dacron full battened Main that is bulletproof and an absolutely great dacron sail ... but heavy as hell. Great off shore sail. The next one will be one step lighter... but I think they have upgraded that fabric and now call it something else.
I am convinced that high tech Dacron is the absolutely only way to go for a cruising J30 that wants to do a little racing.
