Gent's, thanks for the replies.
The previous owner sailed her a couple of times and reported everything went well. I plan to sail her, but knowing my workload, this may be a pipe dream. I've had a Fortune 612 for a couple of years and haven't even rigged her yet.
I sail full size yachts and I bought her as she looks a little like a Hallberg Rassy, something I aspire to….

Thanks for the advice on Nylet, I was going to go to them and / or PJ Sails.
She does have a wing keel, which is used on full size yachts, but needs some filling and fairing before it works properly.
There's no other rigging screw holes in the deck to suggest that they've been positioned other than what we've got although the standing rigging to the top of the masts is wrong, an easy fix though.
I think that the sails are correct, I've added a full photo below.

What I'm really looking for is who manufactured the kit / model and are there any drawings. I could reposition the standing rigging to match a full size yacht, but don't know whether that is correct.
If all else fails, I'll take her to one of the local clubs (I'm in Nuneaton / Birmingham) and hopefully they'll be able to advise.
Regards, Peter.
