Creating new deck tooling for a fellow Unlimited-class competitor’s Victory catamaran is in process at the Miss GEICO shop, https://speedonthewater.com/in-the-n...marine-cat-1-1.

I wonder why Polyvinyl Alcohol “PVA” vs Tape was not used?

searched "using tape for a fiberglass mold", and in this case think it is to protect the boat.

this is another thread i hope gets updated all the way thru bonding the new deck on

PVA would do the same.
PVA is a spray on chemical that dries to form like a plastic wrap . Plus it is water soluble so it simply washes off with water.

The crew at Miss Geico along with Scotty and Mark are 1st class acts!

And once they build the mold, should they ever need a new deck - or portions of a new deck - they have just the tooling! Smart move from a first class team!
