I forgot to mention that detail.

Yes I did apply a PVA release agent. I originally tried to apply it with a PreVal sprayer, but had problems with it clogging up the sprayer. I then used a cheap brush to apply the PVA. When I discovered the tacky areas yesterday I reapplied the release agent in hopes that the area would cure overnight, but I'm not sure if the hardener/gelcoat would set up any more or not.

I think it's weird that about 80% of the new gelcoat curred just fine, but that small area on each hull didn't.
