If the sea conditions allow it, my "cruise" speed is 45, just for the fun. Sometimes 30-40 knots with more waves and a hard ride. However, unless I manage to ride the tops of the waves I have to drop to a slow 20.

Your speed observations are similar for my 7.2 ballistic / 250 single.

She loves going fast but like you say when you can't skim from wave to wave you have to drop from 30/40 down to 20. This only happens in quite significant waves, however.

25knts seams an unpopular speed with this hull.

7m zodiac, 48mph @ 5800 rpm. Suzuki 250. I don't recall GPH but I think it was in excess of 20gph. Much better doing 35mph@11.25gph.

That's insane!

I'll bet you kept it going for a couple of miles to try and reach 60 though or was your ring twitching excessively at that point?

But the fuel gauge was shifting at an alarming rate

Wackwoody - I too would like to know just how fast it does go, so I will temporarily "chuck the missus out" as you suggest

My recently rebuilt Pacific 22 has a Ford Sabre turbo 6 cylinder 250 BHP and a Hamilton jetdrive. I don't have the pump setup for full power yet as it is still running in, but have managed 27 Kts @ 2000 RPM, 1 Bar boost. in general use whilst supporting the Moth Worlds in Hayling Bay used 10-15 litres per hour.
I don't expect it will do much more than 30 Kts once run in. It weighs around 2.5 Tonnes, so whilst being a bit slothlike, is very comfortable in the rough stuff.

I think there is somewhere. Average was about 1-1.5L per mile for an average 5.5 to 7m rib with petrol outboard and deep V

It's best not to know, I turn the display to temp and water pressure etc, far less pain.
