14 day trip fuel burn. I’m happy

Well the 2 weeks in the islands was my first time to see why the fuel burn was going to be like. It was a big consideration when I bought the boat so many people scaring me off. Man hose big Man engines drink the fuel. 70 gallons per hour if you open her up. And considering my 3587 from before sipped Diesel like I couldn't believe I was worried. It might make every trip a pain. Turns out I couldn't be happier.
Now this is all relative I know. But let's remember this is a 55 ton. 60 foot yacht with 1220HP.
We filled up at Kingston on the way out and never had to refuel. I was about half full when we hit Kingston on the way back, maybe just under.
I need to figure out my mileage but i'm more of a gallons per hour guy anyway.
I'll add to this with mileage when I track it all.

Ok I am rounding a little here so don't check my maths. I have it right…

  • Engines ran for 30 hours (each of course)
  • One tank is also fueling the generator I am now guessing that's the starboard side as it used a lot more fuel.
  • We burnt 439 gallons
  • So with the generator use we averaged 14.5gph
  • If i factor some gennie diesel I'm thinking that's more like 13.8gph
  • That's both engines total burn

I can't believe it. I thought it was going to be much higher. Now to be fair we did some slow cursing while towing the tender from island to island sometime literally 7-8 knots for an hour and a bit. But we also did some decent 16 knot runs on the longer periods. Running back from the islands across the strait we were at about 13 knots against the current.
So I am super happy with it. On the 3587 I burnt about 7.6gph on a week in the San juans and that below my mind. But with the extra weight, power and everything that is my beautiful new boat I am psyched.

Total spend for the entire trip was $1010. For 15 days covering Seattle-Kingston-Port Townsend- Sidney- bedwell hrbr- Ganges on Saltspring- Victoria- Roche- Friday H- Jones island- Sucia Islands- Deer Harbor- Lopez- Port Townsend- Kingston- Seattle.
Oh and $50 bucks to fill up the dink and it's still over half full.

Views- Priceless!

I love this boat !

Shout out to the Kingston Diesel dock man. Friendliest guy in the word.
