Thanks for everyones input on this.
It got down to two boats for us, The Ribeye 600 and Brig Navigator 610. I know these boats aren't to everyone's taste, but they suit our lifestyle perfectly.
We test drove them both down at Dartmouth and Salcombe, and found the Brig to be the nicer boat, bit more lively and certainly not as heavy in feel, and then tried them both again, back to back yesterday at the boat show, in horrible wind, rain and a typical Southampton chop. Once again the Navigator came out on top, for us. I must say we have also had excellent customer service from both companies and wouldn't hesitate in recommending either.
Our order has been placed, for a 610 Navigator, with a 130 Etec, in black fabric impression Hypalon, grey gel with red seats and almost every option. We got a cracking deal and a very good p/x price. We are having it built for next March. We are also pondering whether to have a 150 etec on it
