Are you serious?
1 gallon = 3,78541178 litere
I spend 1 liter diesel per nautical mile at 50-55 knots. That works out at 50-55 liters of diesel per hour. Goldfish 29 with 370/380 dmax diesel engine is actually one of the most economical boats you can drive. Well, except for a sailboat
I've been comparing fuel usage with a lot of other diesel powered boats. Petrol powered boats aren't even comparable. I've got 20+ years of experince with outboard powered boats. I have a friend with a Revenger with twin 250 HP Suzuki and Revenger 32 with twin Yamaha 350 HP engines. The gas usage for the latter is 262 liters per hour at max rpm and those engines are some of the most economical outboards you can have. And still he only travels a little faster than my Goldfish at max rpm and his cruising speed is below my cruising speed.
I can travel almost 600 km on one tank (320 liters).
Hope it helps!
Forgot to add.
In Norway, I can buy diesel at 1 GBP per liter for boat usage, while petrol costs 1,5-1,6 GBP per liter.
In Norway you would have to pay 284 GBP per hour for running your boat at 50 knots. I would get away with 50 GBP. Now how is that for economical boating?!
Question for Alan og Bigmuz. Have you ever owned or used an inboard powered RIB, like a top of the class RIB like a Goldfish?
