I didn't say "Don't buy a rib", I said that in this case a rib may not be that best choice. I used to have a 23ft Orkney and although I don't necessarily miss it I have to say it had its good points: cheap to run, cabin and accomodation, large uncluttered deck area, cheap to buy second hand etc..

I think you might be wrongly attributing the fuel economy to the hull... rather than the engine and the self control of the person with the stick. If the performance of an Orkney is acceptable (25 ish knots flat out?) then the performance of a rib cruising at the low 20 knots should be fine... ...but I know where my nervous passengers would rather be [EDIT: in what is effectively the middle of the atlantic!] if it started to kick up! If he's talking day trips and not planning to go serious fishing etc then proper seats for all is probably more important than lots of deck space.

I didn't say the economy of Orkneys had anything to do with the hull shape, it's more a function of not having V6 3.5 litre 2-stroke outboards on the back. My Orkney burned exactly 1 litre a mile and had a Volvo Penta AD31D diesel. The 225hp ETec on my rib uses 1.5 litres a mile.

My processes of logical deduction appear to have failed. I could have sworn that you recommended an Orkney over a RIB for island hopping in the Scillies.

My understanding of this was that if the OP were to follow your recommendation, he would not buy a rib.

I must have missed a sub-clause somewhere....

BTW, if I ever had the choice of an Orkney or, um, almost any RIB, to get caught in a squall in, it would be the RIB.

No, I said I would buy a boat with a cuddy if I were in this chap's position; I didn't suggest he bought one himself. Big Orkneys are good, seaworthy boats. If you're going 50nm in a F5 head on why would you prefer getting soaked every other wave in a rib over being warm and dry in a cabin?

The OP's budget is not going to get him a Rib with a 225 Etec on it... I'd have thought something in the 5.8-6.and.a.bit range with a 90-130ish engine would be perfectly adequate, and with a sensible engine and some self control deliver 1 L / mile.

But he won't be doing 50 nm in bad conditions - he's island hopping round the scillies where he's unlikely to need to fight into a head sea for more than 5 miles! My experience of cuddy "angling style" boats (although I don't think I've ever is that in bad weather you slow down a lot, and get thrown around a lot and feel quite vulnerable (with the waves controlling your boat rather than you). With a rib it seems to be possible to maintain greater speed ensuring you remain in control and meaning your soaking lasts less time. Of course you are really just arguing for why Willk's first suggestion was right!

That fuel survey we did on here a while back certainly supports the view that most RIBs are capable of cruising at 1:1.

I would also agree that a 5.5m RIB with a 90HP is going to be both frugal and lively, adding 4HP for every 10cm accordingly. (That works nicely as an 8.5 with a 210 would be ok).

Edit: Having said all that, I still think a big SIB with a 30-50 would be perfect. (Crikey that works on 4 horses per 10cmm too!)

depends on his / his passengers' view of sitting on tubes/floor...

SIBs can have seats you know

Double jockey and a bench at the back, all removable on captive A4 fixings.
