Greetings and welcome aboard mate.
Seems your boat is a Ray Hunt design and a cool little skiff at that. Lot of talent on this board so I'm sure if you don't behave like a "wanker" some one will steer you in the right direction.
strick, bigshrimpin, hermco and a handful of other regular forum residents have built brackets and are a wealth of information. Good guys to boot and I'm sure they'd discuss the matter with you as time permits.
You've probably already seen this but here's a link wherein someone scored the hull molds, modified the cap and added a bracket to build his own Fairey Hunt 18:

Good luck with your project looks like a very capable little skiff.
Cheers,
McGill
