Looking from the stern of a DE boat- I love the look of round/soft chines with lots of tumblehome. The WESMAC is not so pretty from the stern with the hard chines IMO. That said, the boat is a beast and I would love to own it. :)

Great photos and write up. Is this your personal/company's boat? That's some heavy duty fiberglass they're using. What is "tooling resin"? Is that epoxy or vinylester? Thanks for posting.

To ALL on the forum.

This WESMAC build is NOT my build.
I love this stuff. I volunteered to be the unofficial "information conduit" between the builder and the forum! LOL

The boat is being built in CA.

What I do know is that the boat is being built for a west coast commercial fisherman. Although the hull is a WESMAC "downeaster", the hull/boat will be custom built out as a "southwester" (my term LOL) ,,,, built for the year round sea conditions off of southern California.

Compared to "our" traditional east coast downeasters, this will be a "unique" build out.

Not alot of builds going on right now on the forums. Something to follow over the balance of the cold winter out here!!

100% Osophthalic Tooling Resin is very high strength, low shrinkage and chemical resistant.
It has much better properties than orthrophathalic laminating resin.

Vinyl ester resin is used for all first "secondary bonds" or like a "tack coat" per se.

Try this:

"ISOPHTHALIC" tooling resin versus "Orthophthalic" laminating resin

I think that in the water the boat looks great. Just enough tumblehome and you don't see what type of chine it has. To me it looks a lot better than a soft chine boat that has full length rail along with a quarter rail and a spray rail.

I have to agree with jojobee's logic. I think the full length rails are ugly, atleast out of the water. The Wesmac is a nice boat.

January 12th update

Fuel tanks being built. All tanks including fresh and black water are custom built with composites.

The tanks will be "boxed stringers", part of bulkheads, deck supports, fish holds etc.

What kind of special coating?

I do not know the exact chemical composition of the coating as of yet.
When I'm updated on the final coats of the tanks and entire hull I'll share with all.

I do know that everything will be done/finished with a "Formica" type glossy hard cleanable surface. Final type and color is a ways away.

For what it's worth,

Bill D
