There are huge differences in sail cloth even of the same weight. Fiber orientation can make a huge difference in the life of the cloth and its wind range. But also the heavier the cloth the less stretchy it will be, but the poorer its shape holding in light air.

This is the reason that dacron sail cloth makes less than zero sense for a Cat 27 that is mostly cruised or daysail. If you go with a lower stretch fiber (ideally an aramid), then you can have a sail made with a lighter fabric and still have good shape holding capabilities. Because the cloth can be lighter, it may also cost less, and since aramids hold their shape much longer than dacron and so have a much lower cycle cost as well.

These days buying dacron is a very short sighted and costly decision.
