Maybe - but true. Do you think that most of the fast ferries in the world would use them if they weren't efficient? It was also the propulsion of choice for the transatlantic record run (Il Destriero). Propellers are great, but they are only at peak efficiency at one speed, and one loading condition - at all others they become markedly inefficient

Well, that answered that one then. A bit like buses really, you wait for ages, then a load (of experts) turn up at the same time!

To get this back on thread a little bit, My son used to drive an Ali boat with a Steyer and a jet drive (about 6.5 metres ) when he was working for an oil exploration company in Poole harbour a few years back.

And they were excellent boats so I think a rib with a Steyer and a jet drive would be a very useful craft. The other thing to remember is that Diesel is V cheap so any loss of eficioecy doesn't really reflect in the running costs.

We have a Jet drive boat but havent used it enough yet to offer an informed opinion but my gut feel is that if the engine had a prop attached the boat would be faster, but not as much fun
I need a little bit of Rhythym and a little bit of Blues

Thanks Wavehumper that's what I wanted: a clear answer.
