That is getting close to my dream RIB - can I borrow it for the round Britain race???

Got any performance data?

Petrov · 29 May 2007, 20:19

Ha ha, do you take the fuelcosts

65,4 kn with standard Suz props, 16X26.

95lit/hour and engine on 6100 revs.
The most amazing is that boat is consuming 29,8 lit/hour and engine on 4000 revs.

I assume that is per engine???

I think it proves over 1/2 or 3/4 throttle a 2 stroke or a 4 stroke will use roughly the same amount of fuel.

How fast are you going at 4,000 rpm? Thats pretty good crusing consumption.

Yes per engine, boat is doing just over 40 knots in 4000 revs so the cruising consumption is great.
Yes about the consumption of 2-strokes but dont forget the oil and noice

Petrov,

Have you fitted a Suz 300 on an Osprey yet? If yes, how was the top speed and fuel consumption at 30 kn?

regards,

Paul

Petrov · 30 May 2007, 08:58

Not yet, but will hopefully do in short time.

Hi Janis.

Notice its different hull and tubes on this one. Is it a new Ring model ?

Petrov · 31 May 2007, 07:42

No, its a shorten version of a 13m and the tubes have been built futher into the hull.

Hi
Two quick questions.....

Is petrol cheap or free there?......

and also more seriously if you have three engines, how are the props set up?
Thanks
Tony

Not cheap, approx same price as UK but we have the pos to withdraw tax (also VAT) on fuel when its commercial use.
Props are today same, 16X26 standard Suz props but are thinking of putting a 4 blade on the midle engine, will keep you updated of how that will be.
