Picked up a mold for an 8ft boat. Trying to figure out a rough cost estimate to lay up a hull. How many layers of what weight fiberglass is needed or how thick do I need to make the hull? I started a thread awhile back but it's been inactive for too long so I started a new one.

Re: Boat building question

you can always re activate your own thread, the red banner doesn't apply to the original poster. Did you get a layup schedule with the mold?

Not sure what a layup schedule is. I'm going to say no. The guy I bought it from was using it as a boat. He didn't know it was a mold until I went to buy it and told him it was.

Ayuh,... Got any pictures,..?? I've never seen a mold that Could be used as a hull,....

"Not sure what a layup schedule is."

It's the blueprint so to speak, how much of what material in what order at what time,...

Re: Boat building question

Just ask a mod to combine the threads. Pick which thread title you prefer & have them make it the primary, and add the other to it........

[h=1]Fiberglass boat build[/h]
As noted in the thread above, you probably need to apply gelcoat to the mold (after it's prepped), if it's a mold to produce gelcoat covered boats, and add the correct layers of glass into the mold. Once cured you pull a boat out of the mold.

Is it a BOAT mold or the HULL of a boat mold. It may only be the lower half of a boat, from the rubrail down (roughly depending on the style of boat) or it could be any number of boats that are produced w/ only the hull being made in a mold. What other structure does a boat made in this mold require? Stringers, bulkheads, deck, flotation foam, built in seats or storage bins that add to the structural integrity of the hull........


What types of glass, what weight of glass, what order they are laid into the mold, how many total layers of glass would all be part of the fiberglass 'layup schedule'. The layup schedule & the structure questions above would be on a blueprint of sorts as Bondo suggested.

W/ out pix of the mold, it'll be hard to recommend a glass layup schedule or figure out what else a boat made in this mold would require.

If you knew that boat maker the mold originally came from, you might be able to find an example of a previously made boat & reverse engineer how it was built..................

Re: Boat building question

cant get pictures to upload. the boat is 8ft. similar to an Olympian pram. just from the info you guys have given I don't think its a project im going to take on. I would be money ahead to find a 10ft aluminum or a bass hound as this boat will be mainly used for pond fishing. thanks for all the info.
