Fuel Consumption F37
|
Just wonderd if any andbody has run a Sealine F37 with KAD44s over a couple of seasons and what kind of fuel consumption they are acchiving. I know that there are so many variables as to make the question a little meaningless, however I seem to average about 60lts per hour at 3200 rpm, cruising 20/22knts. Anybody similar?

Hi there, I have a Fairline Targa 37, on KAD 44's and would say most of our running is at about 24-25 knotts.
Burn is roughly 56 litres per hour.

Your traga will be completely different to the F37 Jas - lighter boat, on efficient(ish) outdrives vs a heavy fly bridge boat on shafts.
I would expect your 56l/hr to be closer to 80l/hr on the F37

@ 21knts cruise you have calculated 1.6 NM per gal
If working out my range on an F37 with 44s I would work on 1.4 mpg @20 knts
I dont know the F37 intimately but I know the predecessor 350, 1.6 mpg @ cruise speed of 20 knts .........no chance
I think most of us work in mile per gal or litters per mile

We seem to average around 1.2 mpg with KAMD43's cruising around 22-24kn, but we are very heavily loaded. Best we ever got was 1.4 to the gallon. Anyway, at 1.2 mpg it comes out to around 80 l/h like Jez said.

My F37 with KAD 300s returns 1.1mpg at 24/25knots, about 3,600 rpm
It's been pretty consistent over 6 years. KAD 44s should return a little better.
Reckon most of the fuel is turned into soot and is deposited on the transom....

From an sms i got our 28 footer has just been "toped up" with £800 of Diesel(1100euros)& back on her mooring.
Thats what i heard from my son i dont think were doing much better
Id just found an old car mag which listed new cars i could have bought a new mini cooper"s" lotus cortina alfa even a BMW for less
In the med diesels very expensive almost 1.50 liter and set to double by the end of the year

Re: Fuel Consumption F37

Hi,
What about crusing at lower speeds - say 10 knots. How does this affect fuel consumption and is it better to run on one engine at that speed - assuming a diesel powered cruiser like a Targa 37.
Thanks

Re: Fuel Consumption F37

10knts is way aboive displacement speed for that length of boat and will be uneconomical.
If you want to run effficiently then you will need to drop to about 7knts and then yes, one engine would use the least fuel.

Re: Fuel Consumption F37

Thats hard to do.Ive tried to keep the speed down but still on plane after a few minuets its to much
Open the throttles the noise of the engines in sync the sight of the wake is wonderful & without useing a lot more fuel.
To motor slowly is then far better to have a sail boat & quiter
