Hi Folks

Would anyone have a rough idea what the cost of materials (resin, mat etc not including labour) would be to lay up a 35ft fin keel yacht hull?

Thanks

I'm no expert, but I would estimate the weight & cost up that amount of resin then add the cost of the area in matting x 3 or 4 layers? Remember the cost of the hull is only about 1/3rd the cost of total boat. So add double your hull cost for fittings, fit out & rig.
 
A place like cfsnet.co.uk will give you bulk prices.
I would think grp materials are the least of it.
£2 per kilo? csm and resin
4000 kg?
Do not forget ancillaries, a lot of wood still goes into boats, ballast, hatches, toe rails, Chainplates etc could easily add up to more.
 
We are currently looking for a good home for the production moulds for the Anderson 22; a chap who runs a grp boat-building business already, reckoned a hull would cost roughly £2,500 in materials, that may have had some labour allowed - I only heard it 2nd hand.
 
1000kg Tank General Purpose Resin

Price: £1,849.50
(Excluding VAT at 20%)

20kg Pack White Gelcoat - £70 +VAT

Acetone Cleaner 25 litre -Price: £30.99
(Excluding VAT at 20%)

Chopped Strand Mat 600gm - Chopped Strand Mat 600gm - £73 (Excluding VAT at 20%)


So you are looking at about £2750 per tonne, and you will need at least 3 tonnes.

This basic without all the other stuff like mould release agents, polishers, other grades of mat, unidirectional mat, kevlar, epoxy resin.
Also, it will depend on your ability to control the layup. It is very easy to over egg the pudding and end up with a heavy layup, or even (worse maybe) light.

Buy a boat and go sailing instead of spending 5 years making a boat, which is close on 15% of the average sailing career.

A typical modern 35 ft boat (eg SO35) displaces about 4 tonnes excluding the keel, but I think at least 50% of that (maybe more) is timber, tanks, engine, batteries, rig, fittings etc. And on my SO35 there's even a fair sized lump of concrete under the starboard gunwale midships (to balance the aft water tank to port probably) So maybe 2 tonnes or less of actual glass and resin. A 1960s/70s era 35 footer might have twice this weight of GRP.

I agree, but our boats are laid up by CNC programmed spray bots to a very precise pattern and dsetail. Also, we have low pressure injection moulded deck, which dont vary by much.

I think that most plans sold for build will generally specify a heavier layup to counterbalance the lack of control in the process.
