‎44' Aluminum V Hull with FPT 560's + ZF 2-speed/ASD8 Inline Drives

Made a 260 Nm trip during the weekend. First a 130 Nm leg to Stockholm to the start of Roslagsloppet.
Then we followed the race all the way up to Öregrund, about 80 Nm.
Finished the day with a 48 Nm offshorerun out in the Baltic Sea(2-3 ft chop) home to Gävle. 42 min = 77 mph average.

Last tests before winter.

ttt thought I would bring this back up , how's the boat running

Boat is running fine! But the owner is in a worse shape...

Rode a lot of motox/enduro in the wintertime and reinjured my back, two herniated discs plus spinal stenosis (old injury).
Surgery in September so I will only do two shorter races in Norway/Denmark in July.
Skagerak Across- 140 Nm and the Skagen Summer Race- 80 Nm.
The early plan was to do some longdistance recordruns, like the Swedish Blue Ribbon, 720 Nm.

Were out yesterday and tried some modified propellers in a nice 3-4 ft chop.
But always back to the 28-18", 5-blades. The 29-16,75" are a bit faster, 2-3 mph, but the 28-18" work in all conditions.
Very little need to trim and nice grip.
80-85 mph with 600 l of fuel and all raceequipment like tools, liferaft, anchor, second 700 l fueltank etc.

Looking forward to the London-MonteCarlo race next year...

Did you ever make note of the fuel burn at various speeds?? I wonder how those FPT compare to the 550 Cummins.

In ag applications the fpt motors around 500 horse and up are 2-3 gallons a hour better than a 550 cummins across the board

Pstorti,

Never more than 1,65 mpg at any speed. Boat weighs 11000 lbs raceready, 220 gal of fuel, no crew.

44 ft Endurance Diesel
Even at lower speeds you don't get better economy? what about at 40 or 50 mph?

Looks like the hull is so much more efficient at higher speeds. Usually never run below 60-70 mph

1.4 mpg @ 80 is sweet in a big V bottom , actually in any boat :) . How many hour's on them now ?

About 30 hours of running.
