I've seen your boat and it does look nice. I've checked other threads, and there seems that different users get a broad range of fuel consumption on a boat/ engine combo of this size. As Codprawn quotes, it seems that some engines typically burn 85 ish lites per hour
I'd like a boat of that size, but this sort of consumption could mean that a days boating could cost 300 quid!!! I would be running at cruising speed most of the time, so hopefully consumption wouldn't be up in the dizzy 80's, but even at 50 litres per hour, a day out could be more than 200 quid. Last RIB I owned was a 5.1 metre Tornado with 60 HP Yamaha 2 stroker. A different animal.... I think.
Anyone else have typical fuel consumption figures for a 6.8 M+ rib with 225 to 250 hp 4 stroke??
