Hi all. I'm in the process of looking for a new boat. We have selected a Bluewater in the 47' to 51' range. I see that most are gas powered. What could I expect to burn while cruising?

Thanks

Hi John,

I have a '79 45' Sport Sedan with the 270hp engines (350ci). This is a semi-displacement hull.

I get around 1mpg cruising around 7-8 mph. I believe you are talking about the newer models and I am sure they are more efficient.

I believe any of the bigger motors, 350hp, would be more efficient since they don't work as hard.

Whatever you get, I am sure you'll enjoy it.

Hi John,

The general rule-of-thumb for large gas powered cruisers is 1mile = 1gal.

 I have a 1979 40' (47' OAL) Sport sedan with 454 Crusaders (350hp) and I average just a tad over 1mpg @ 8-9 mph and just a tad under 1mpg at a cruise speed of 22-24 mph.

At any other speed, it drops to 1/2 mpg or less.
