Ian , I would say that the WOT figures are quite high for a 6.3 mtr rib like ours
This is now my third Parker 630 diesel and still have my fuel log of the first one . Did not run a fuel log on Seahawk 2 and have not started one yet on Seahawk 3 probably cos not been to Cowes with it yet
looking at the fuel log for Seahawk I note
20/07/2003 Littlehampton 121.6h on the clock, full tank
20/07/2003 Cowes 125.5 on the clock, 22.40 ltr of fuel taken
02/08/2003 Littlehampton, 128.4 on the clock, 31 ltr of fuel taken
02/08/2003 Cowes, 131.3 on the clock, 22.3 ltr of fuel taken
03/08/2003 Littlehampton, 134.6 on the clock, 45.3 ltrs of fuel taken
Don't remember whether I filled up as soon as I got into Cowes of after lunch but guess after cos it takes on average 1h 30 min to Cowes and on a good day 1 h 10 min in my rib. The sea state would have been fair
The average speed would hv been say 26 knots , the max speed on that particular rib was 32knots at 4400 RPM, 21: LASER II prop, we only use them
I would say a 6.3 mtr rib should not use more then 10/15 ltrs max per hour
My current Parker 630 known as Seahawk 3 is faster
then my previous ones and I am yet to venture out to Cowes and will be keen to compare fuel consumption.
The Mercruiser 1.7 TDI is a superb engine for a 6-6.5 mtr rib you cannot go wrong
