Last year, when I inquired with my sailmaker for recommendation on new set of "white dacron-like" radial sails, that could be used with integrated lazy jack/sail cover and jib roller, he recommended two materials:
- Dimension Polyant AP Blade
- Dimension Polyant Square
(this one being pretty much race-ready material without going into the laminate sails)
He also mentioned both materials do not need special handling, unlike laminates.
