I can help
I've just taken in a 2003/4 Ribeye 600 Playtime with Yam 115hp 4 stroke on the back. Your welcome to put some fuel in it for a test drive, load it as you see fit (provided it's within ratings and you bring the necessary life jackets etc). That should help determine what you need.
The one I have is for sale too for stupid money (under £8,000) but there is a story behind why it's so cheap... Which I'm happy to explain if required. Perfectly function able boat though! In fact I'm hoping to use it myself this summer so please don't buy it :wink:
Another option is the Ribeye 785 on Boatshed hamble (i think) with yam 200 Vmax 2 Stroke (no trailer) priced £14,000 - a customer of mine in Ireland told me £11k would buy it - not sure if that's correct though. I think there was one on here too could be the same one.
