Thread: Costs involved in creating a fibreglass boat

have you looked at Pelin Dory plans for home building, similar points, shallow draft,stability increases with load,easily driven.

yep dorys are pretty common around here for the netting guys,
one with a rail along the bottom to lift it up and plane easyier would do, but its not really what I was hoping for
I literally have 3 boats at the moment, 2.7m 5.2m and a 5.7hard top
this is just me getting an itchy arse

I just want one by no means do I need one

If I was to flip one upside down, and essentially just lay the glass over top of it then pop it off and put the strenghtening parts inside would I be able to go that way and bypass the mould step?

is it possible to get it smooth this way or will it be as rough as guts

Yep you could do that. The shape would need to be angles that would allow you to easily pop it off, hopefully with out destroying one or the other. They use a petting gel or similar mould making gel so it doesn't stick. Inside of yr boat would be smooth, and the hull surface would be glass textured, and not smooth.

You could fill the hull with micro balloons and epoxy, then you would have to fair it back with long boards. Give you and a couple of mates a good work out.
Once you got it looking good with faired filler, you could use a number of paint systems to prep for painting.
There are high builds you can use to fill in the small holes before undercoating.

I'm not sure about polyester resin filers as I haven't used but I'm sure you must be able to get them.

The rule of thumb for Resin families is epoxy will stick to polyester but not other way around. Most production boats are glass and polyester resin.

All ways hard to estimate how much filler is required and the associated costs.

fair enough mate thanks for the info

You could also build it with glass over a foam core using temporary frames, either internal or external. This would be much lighter than glass over ply.

If that involves anything to do with polystyrene I wont even consider it, I cant stand touching the stuff

No definitly not, its not strong enough, something like Corecell or Divinicell, it is even worse to touch..... Its very comon for sail boats

Starco Panga on Trade Me I can see the allure. This looks the shizzle. Are they Chinese made? Can you import direct?

This bloke has plans for different styles of boats, glass over ply builds. Don't know what size you are looking at, but this is for a 24 footer.

that is a really good looking boat, no delta pad tho and lacks the steps of the hull so its not really a panga
