I need some help in repairing a little utility dinghy I have just bought. Really got it for the sail and mast for a future project but hull is too good to just throw away though its reasonably heavy at 65kg.
The Seabird 3.2 is fibreglass boat produced by Dinghy Developments in Auckland New Zealand in the 1980.
This one was probably stored upside down because all the gunwales and outboard bracket have all rotted away.
I'm not even sure of the actual dimensions of the gunwale but the seats etc. are clear grained and light coloured and varnished to a pale honey colour. Density is about 503kg/m3 or 31lb/ft3.
Is this likely to be Qld Hoop pine ? or similar NZ timber ?
Picture on the left is what I'm aiming for. Picture on right is what I have.

The new gunwale has to be bent to fit the sheerline as well as the very tight (bathtub like) curve towards the bow.
There is also not a lot of fibreglass strength in the gunwale flange so I cant form it in situ on the hull as you would with a wooden boat.
I presume the original was steam bent on a mould then mated up to the hull later on. I can try to replicate this process and perhaps laminate the required thickness 2' ? (x 1' thick?) out of 1/2' staves.
But before I start is there a simpler solution.
