Here's another question about sail weight
If there were a rule on sail weight for "string" sails (and if the class doesn't put a weight restriction that effectively blocks ever using a string sail), then the weight would hopefully be different than the current weight for Dacron which the rules now say is a minimum cloth weight of 6.25 oz.

So the question is; would there still be a minimum cloth weight for Dacron Sails of 6.25 oz that is different from the weight limits for string sails?
