Something that can be completely glassed in one session and then bolted or screwed to the boat is a good candidate for vinylester; pilot house, tackle station

You can start a project with epoxy and come back within 24 hours without having to sand and you will still get a chemical bond. Vinylester requires sanding to get a good bond. Basically if sanding is easy than vinylester but if its an area where strength is critical (bracket) epoxy. Not that vinylester won't work but epoxy is much more forgiving of applicator error.

Real good example is if I was replacing my transom from the inside again I would try vinylester on my next go around but if I had to replace it from the outside as in cut the skin off then I would use epoxy.
