Vinylester is epoxy. And the low viscosity stuff you have- Vipel F010 (right??) will likely get in a crack as well as or better than a thick epoxy (like what you get from West System). Everything I can find shows BETTER mechanicals than something like West System- strength and elongation. Different hardener systems, but both epoxies. So I'd be comfortable with what you have, personally.
For the keel- yeah, fix it now. Lots of layers, getting progressively wider. I have some biax and DBM left over if you want to try something different. And I think some kevlar woven roving. That might be interesting on the outer layer. It will take you a week to cut it.
With respect to the white looking glass: Maybe you got bad/ no sizing on the glass, or it got dirty/oily or a silicone on it?
