There are many of these ribs around the North Wales area now. They have a great hull and handle a bit of rough no probs. PVC toobs, (Q the debate) Dont get the model with the bench seat, get the jockey seat version every time.
The 5.5 Menai needs at least 90hp-115hp the TDLI motor is a good choice.
Speak to Tim & Jason at Menai marine, they are very helpful and good blokes to deal with. I visited my hull being manufactured often, seeing every stage of the build. After sales is also excellent.
