Well that was a lot of help, some great views but as most of it seemed anecdotal, and the real first hand experiences seemed to confirm several things.
1. Ribeyes in Hypalon were in fact ok boats! - Maybe not the best, but also not the most expensive.
2. Ribeye have a good after service
3. Ribeye have a family friendly layout (not everyone wants a single jockey at the front! - A sun pad has multiple uses!)
4. Lots of people like to pass on tales of woe!
Anyway I found what I need, at a price I can afford.
Just need to give it some real testing now. Its a Ribeye 650, 2004 model w/ Merc Opti 150
I look forward to seeing some of you around the W. Solent in the coming weeks.
Now looking for Lights, GPS and DSC radio, and a good electrician to fit them ??
