I have the Ribcraft 7.8 with Yanmar 240HP/Bravo 3 drive.
Love the boat to bits, have done quite a few a hours now and have great confidence in the Ribcraft. Am often out in rough conditions (much the the displeasure of other people joining me), see http://rib.net/forum/showthread.php?...0&pagenumber=2
the more I go out the more I decide the RIB has much more left whne the going get rough.
For me it was between Humber & Ribcraft but Ribcraft won as Humber kept pushing the 120Hp 1.7L engine in a 7M, which i belived was under powered.
I also belive the quality was better on the Ribcraft from the boats we saw at Ribex, but that could have just been rushing the show boats to get to the show ( Note Humber, these show boats is what people are going to judge you on)
With the 240HP I get about 36Kts with 4 people.
I mainly run at about 3000RPM, which is delivering about 170HP at the prop and gives about 25-28 Kts
As far a torque goes the Yanmar 4LHAM-STZP gives about 625 Nm at 2600RPM.
Personaly I think Yanmars take some beating.
Fuel is about 0.8 to 1.0 L/NM
As far as build quality, well not found anything wrong yet, built like a tank, but this does have a weight issue. Ribcrfat have now addressed this with their 7.5 which I belive is much lighter.
If I have to pick again it would a Ribcraft, good boats, good service only slight issue it delivery as they are often over booked.
Pity your a long way away, you would ahve been welcome to have a run in mine, as I am sure may people would do, to see what suits you.
