Good boat - I have the 3.1m version which goes really well with a 9.9hp.
The only downsides I see with the RAB are:
1. They're bulky when packed away, due to the floor design.
2. They're quite heavy for their size.
If you can live with these disadvantages, then they're a good all round boat.
I'll mention, before Codprawn beats me to it, that transom wheels are a great thing on a boat of this size/weight.
