IMHO, though i am no oracle. !!!!! Pls Ask others too.
Ribeye is a bit like ford if avon adv is like vauxhall! (Pretty similar and people argue either way) They do what they do and some like them. A lot of people on here seem to be very in to their boats. They have either functional/commercial orientated boats that go out in anything and they don't care it's raining, or they pay quite a bit of money for some very nice seaworthy luxury ribs. They often use them commercially, use them a lot or just have a lot of money.
Avon adv, Ribeye, Valiant kind of hit the mass market, not so over enthusistic/nerdy ribbers, who just want a rib over a dory/hard boat as they are better in a sea. (cue those owners who will reply differently)
That example is fairly underpowered. 90hp on a 6m going 30 knots is slow.
The average imho on here for a 6m is 115-135hp
Our 6.3 Humber for example is a 175 and most
5m 60-75hp. But they are ballparks. If you are just fishing and plod out, it might suffice. For skiing or playing in the rough. It will not have the ooomph needed.
I need to get back to work.
