I have hull # 191 built in 1985. I have many gel coat cracks in the stern and starboard bow. Is this common? I have moisture in the stern that keeps evaporating out after I put primer on it. Any ideas on how to fix it. I have gotten to the point I am going to grid it down and put one layer of 6 oz cloth and epoxy resin.

There are a small number of boats with cracking in the gelcoat. Effective repair procedure for cracking is grinding out the cracks and some of the underlying glass then re glassing/fairing and paint. Any other method is short term patching. So yes your on the right track. Peeling the transom with a gelcoat removal tool may be the easiest method. If you have moisture trapped there it may need some time to dry out before glassing.

Which resin should I use? Polyester, epoxy or vinylester? I have all of the gelcoat off in the stern. Should I v out the cracks first or just glass over them?

The cracking occurs in the layer of glass under the gelcoat. So I would remove the next layer of glass. Once you are at the kevlar (yellow material) you are safe to reglass. I would do it with epoxy since it's a secondary bond.
