Mustang Marine built an 11m Ocean Dynamics boat for Bear Grylls' Artic Challenge Artic 2003 Challenge - Ribworker D - Class | Mustang Marine Ltd
so this definitely isn't it.
they might have built others for him but I don't have details.
They do an D825 which is inboard jet drive and a C825 which is typically supplied with twin Suzi 140's.
More info on their website under "Ribworker".
If it's a Mustang boat, I'm sure they will have some info on it. They've recently gone into receivership but the same guys are still there and they look like keeping going.
