Sorry can't help you on that, but wouldn't you be best off running some consumption tests on the boat itself - there are so many variables that can skew results between one boat and another?

FG, as Brumby says, you really need to do fuel trials in the actual boat, as things can be soooo different even between similar boat types.

However, as a very rough guide, with 2 x 200hp d/props (1987) in a 328 Powercat flybridge I used to get between 1.8 – maybe 2.4L/nm in total, per trip, depending on conditions, loading & cruise speed, and how much trolling was done. This is very low consumption for a big boat, but we always did a lot of trolling. Shaft drives are less efficient than DP’s, and the PC328 was a very efficient hull to drive due to its design.

Mate, best to plan a trip out prior, and do some trials. It could save you a lot of pain.

Should be a good trip - Musgrave is on the (very long) list of must do's. I see the long range forecasts are punting fairly settled weather with a bit of wind from the SE. There is a low around up north, but expected to remain weak and too far offshore to interfere.

Enjoy!

Had a pair of 165's in a 328 Powercat many years ago and it would burn between 50-60lt p/h combined at a cruise of around 3200RPM. The 200's are similar so I would work on around 60lt p/h.

Cheers,

Lee
