I've seen some very poor designed fiberglass home made boats that I would not give a hundred for. Shape and design is real important. Can you get a picture of it and email it? I'm sure there is many out here that could give you more advice on this boat.

Also the picture would give a clue to the value of the molds if they would be placed for sale.

I have built 3 fiberglass drift boats myself.
1 to light
1 to heavy
1 about right, but they all worked for us at the time.

I now row a aluminum but still own a fiberglass driftboat.
