Hi Chris and welcome to the forum.
A not uncommon occurrence I am afraid.
It would help if you could post pictures of the boat, a guide to adding pictures is on the front page or poss down the right hand side, and to say where you are roughly, as collection is usually the only viable means of getting something like this anywhere, posting is expensive and tricky for boats.
It may be useful to know if it looks like a kit part built, or if the boat was being built from scratch.
