Trawler wanna-be: What are fuel burn rates

[Cartouche]

Hi, just starting our search for our next boat, and coastal cruising is our highest priority (not a marina condo!). We have seen numerous motor yachts and trawlers with big V-8 gas engines and various sizes of diesels, and were wondering, what are typical trawler speeds and fuel burn rates?

Would you folks share what boat you have, typical cruise speeds, and fuel use in mpg?

Thanks,
Allan

Here's the Stats for Cartouche converted to US Gallons

 

[Spinner]

Spinner is a 2003, 42 foot Nordic Tug. The single engine is a Cummins 6CAT-8.3M
(Model known as Diamond). It’s a great coastal cruiser!!

I usually run at about 1200-1400 rpm. My speed over ground and fuel burn vary greatly with the tide and current, but I can estimate them as 2.0 -3.0 nm/gal. Speed is about 6.5 to 8 kts.

In the Pacific NW, tide and current are major factors....

Maybe it is just me but I would stay away from any gassers and or wood hulls.

People worry excessively about fuel. In most cases it will one of the least expensive parts of boat ownership.

Excellent point.
For older boats, this is so true.
