Hello Des,
I am surprised that there are no replies, 70 readers, to your important question here.
I personally would like to know which approach, frame and plank or fiberglass has,
in the opinions of the many experienced here, the most favorable attributes towards
less work and energy put out and finished product looks and strength.
Personally, I have always avoided fiberglass but the fact is, fiberglass hulls look
"knock-out" beautiful, are strong, and light weight. And I would love to get
involved the the fiberglass tugboat "mold" world. . .or would I?
Part of what I would like to hear about is if I am right in that a "fiberglasser" has to build
their tugboat with a frame and plank anyhow to have the form to fiberglass. I don't
even know if I have that right because I have never worked with the glass. With out
some input here, which would be quite simple for many to give, I only know what
I don't know.
One of my friends sent me this picture of their fiberglass start on their tugboat. Is it
really that simple?

And below here is one of my approaches. . .ambient it rough, very rough, but it worked
out alright. A lot of work, wood filler, and I never did achieve the "right" tugboat hull look.

Again, a perfect and strong question Des, thank you very much,
Michael
