Always seemed to get about 2 nmpg whether at 16 knots or 20, tide didn't really effect it, maybe a knot or 2, but weed and crap would.

Loved her, never should have sold it..... off now to cry in my beer

so what boat you got and what engine? Trophy 2352 re-engined with 164D Mercruiser (200 HP V6 petrol as built)
how much fuel per hour hour @ cruising RPM ? Average between fills (300 litre tank so that isn't often) 10 lt to 12 lt per hour so that covers everything
top speed and cruising speed ? Top speed 29 knots empty and with a clean bottom. Usually cruise 20 knots

Chosen cruising speed 20knots at 3200 rpm

28 litres per hour at chosen cruising speed.

All plus or minus 2/3 knots with/against tide


jezzzz. 28 knots top speed andy. are arvors rated to do that, never knew they were made to go that speed.

guess im getting an arvor next then lol

That is fully loaded as well. Arvor base their figures on a boat with no load, minimal fuel and water. A standard 250 with the Mercruiser will do about 21 knots flat out and cruise at 15. Until the engine blows!!

my raider has a 90 optimax revs out at 5200 and at best will do 32kts with a bit of chop can always get 28 /30 if your bod can take it, uses 1ltr mile a bit less if tickling along about 26 always 2 or 3 up and loaded with pies, tried to get crew in mid  air suspension but still returns about  the same economy LOL
if you have to measure it, its too small!!

I'm not as clever as you lot but I will have a go.
My boat is a quicksilver 650 weekend with a 100hp mariner it needs to be cleaned and anti fouled so its running a little slow.

At the moment I get around 17knots at 5200rpm flat out but it drops to 15knots against the tide......I get about 30 miles on 50 litres I think.
That's with two people, and loads of crap on board.

Freshly painted I get around 21knots

Warrior 165 with Suzuki 80. 

27/28 knots when I'm in a hurry, around 18-20 knots or thereabouts cruising
No real idea on l/hr.  What I do know is that a 25l tank of pertol normally gets me from Langstone to Selseyplaice marks and back ...just
