To start with, again, in the total boat building process, I mean the complete sail ready boat,? including engine, or a sailing rig,
(Excluding Electronic gadgets like on a Christmas tree, which would make the equation even more favorable for Epoxy)
the cost for the Epoxy is only a small part.?
Vynilester was developed, to make swimming pools built with concrete, waterproof. So, it is used to protect a Polyester.
Vinylester is only fractionally cheaper than Epoxy. To get a homogeneous structure, it is not worth not using Epoxy.
