well I am not to that point yet and understand that the glass will not bend that good it can be done and if you think about it people put "skags" on to help if you have a knife blade shape to your hull in front and rear this would help at least in small boats I've seen. personal I intend to put a blade shape on mine with about 1/8 inch width at the point.what ever way you go you need to decide what is best for your needs.
