RIBase
What I meant to say was - more than a mile per litre up to 28/30 knots, less than a mile per litre over 30 knots.

I imagine my boat is a fair bit heavier than a Leeway 6m?

Ha ha!!! Slight issue yesterday with a fuel pipe under the cowling. Halfway through mine and the kids PB2 course!!! (Talking of which I can wholeheartedly recommend Stormforce Coaching at Southampton!)

10l/hour is the average consumption from it's 15 month life with us. This includes a lot (50 hours+) of Portsmouth Harbour-IOW commuting for sailing, a few beach days, wakeboarding, towing inflatables etc. Most of it's use is at circa 4k revs (25 knots on the current prop).

Interesting consumption from the PB2 2 day course. With 4.5 hours of VERY slow speed (sub 6 knots) and 30 minutes of 20knots work on the first day it used 10.5l of fuel (I had the embarrassment of going through the Hythe lock to get that amount of fuel!!!) and in 4 hours of high speed work and an hour of sub 6 knots yesterday (the second day) it used 40 litres, giving it an average of less than 10l/hour for the two days!

I thought so but the fuel spreadsheet on the laptop (I haven't got anything hardwired on the boat, unlike the no. 2 boat) confirms it time and again. It shocked me so much that I asked both the guys with the no.2 boat and also Doug at Seaforce who has a later version with a 90 and does nearly as well!! Scarily good.

Tony, the other reason that my rib smelt recently is that I brimmed it and it shot a bit through the vent on trailer trip back to the marina!
