He's doing 40+ knots and cruising at 30 and you think he's "underpowered". Are Atlantic 75/85s underpowered too?

our 175 pushes a 6.3 at 50mph or 43knots flat out

He says he is using 40 of petrol in 4 hours. I doubt he cruises at 40knots either, if he is, he is using way more fuel!

cant comment on atlantics, but just thought 25more hp than ours, as a less torquey 4 stroke, pushing an 8m boat may be slightly lacking. IMHO. That was my logic.

I think the boat's underpowered as well. I also think there's a bit of fibbing going on througout this forum when it comes to fuel consumption!

Careful lads - we'll have Timw on here in a mo', calling for a Name & Shame

Hows about we leave the poor newbie gadge alone? - I don't think he really knows what fuel he's burning.

BTW, at 32 and 35 kts respectively at WOT, those 75s and 85s are positively sluggish by FIBnet standards...

Indeed - but there not necessarily underpowered, they are well equipped for the task they do, just as the OP's boat is probably giving him more than adequate performance for the sort of stuff he does (which probably isn't that different from the rest of FIBnet - most of who rarely spend all day at top speed anyway)

Underpowered... No and Yes.

Depends on how you use the boat... And how much load you drive around with.

For me it sounds nice, cruise in 30+ with 8m rib....

(Last summer i had opportunity to drive a Fountain 42 in 75 knots, but then you need a crazy budget for a summer)

"Fibnet" - that's funny! When I said (toungue in cheek by the way) that there's fibbing going on, I meant on Ribnet as a whole and not this thread in particular. I have to be honest, my ETec burns a shed load of fuel. This afternoon I was doing 45.6 knots (52mph) around the bay and using 76 litres an hour (1.6 litres per mile at that speed). I also felt that in a 6.8m rib 45kts was plenty fast enough (for an old git like me, that is).

Yeah, we know that you used a low-loader to get to Avranches

Fibnet, quite true by many.

My wife calls it "ribnet borum". Always being told to get off.

50mph in a 6m is fast enough fir me too. Anything other than flat calm, it's too uncomfortable/dangerous anyway.
