Have you thought of trying Garment vinyl?. Must be ironed on. T-shirts go into the washing machine every week and the vinyl stays on.
Only problem you may have is if the "sail cloth" has a waterproofing chemical on it. Might not stick then.
Or make a mask with sign vinyl and paint the cloth with a water based paint.
