One liter per mile - what speed for your RIB?

Can you imagine trying to do that down here with all the States departments to notify and big brother attitude and forms to fill in etc. Just wouldn't be worth the effort. And anyway, there'd be no cheap moorings, camping on the beach, nor the same easy going attitude that Alderney manages.

The old boat (6.5 Vipermax/150 Opti) liked approx 24-26knts for optimum speed/economy. This would give pretty much 1:1. The current set-up sits more comfortably at around 28-30knts. Not sure exactly what Nm/Ltr I'm getting owing to not having the Icommands entirely nailed down.

Likewise, with my Humber i'm at more than 30kn for a 1:1 ratio in calm conditions. I'd say 32kn as a guesstimate.

Summary so far, with estimated 1:1 speeds in bold at the end:-

Zubenelgenubi: 30nm:25L @30kn (90 2/S) = 0.83 lpm 33kn
9D280: 35nm:30L @20kn (25 2/S) = 0.86 lpm 22kn
9D280: 24nm:30L @mixed (55 2/S) = 1.25 lpm 20kn
Leapy: 46nm:26L @20kn (90 4/S) = 0.57 lpm 28kn
Cypman: ?nm:? @30kn (140 4/S) = <1 lpm 35kn

Well, it's varied over the last few years from about 55p IIRC to 62p on my last fill up in October (and it's green BTW down here). Gloat over

Look. I don't know you. You're probably a very nice man too. But. Would it be impolite of me to state for the record that your views on fuel prices suck too?

[Erin]

Absolutely not. And if you care to know, our tax never exceeds 20% and although we now have an equivalent of VAT it's only 3%.

Mind you, our snow's pretty crap. Make you feel any better?

I dont know how you manage to live!

It's tough, but we've got a multifuel stove, so at least we can burn our excess banknotes to keep warm in this weather.

Aha! Back on topic...

Let me see. You live on an island with a low rate of income tax and low rate of VAT. You also enjoy a low rate of fuel duty and have a boat. Hmm.

I'm early retired, fit and healthy. Do you need a butler?

[Erin]

I'd love a butler, but sadly unless you were locally born or you've lived on our island for at least 5 yrs, I'd have to give preference to a local without getting special dispensation from the powers that be. Population control they call it (an alternative to the free contraceptives that most other countries might use!)

Errm, one thing I forgot to mention, you'd need at least £200k to buy a half decent one bed flat here and half a million for a good 3 bed semi. And that's an island wide price, you can't go and live in a cheaper parish and save a few quid.

It's not always as rosy as we try and make out . Asset rich, cash poor.

[Nos4r2]

I get around 1 mile per litre at around 23kts in calm (but not flat) conditions. It uses a fair bit less if I drop to 20tks though.
