cruising range fuel/consumption

[benlui]

What is your boats cruising range/hrs (under power) ? and what type of boat?


Shipman 28
Fuel tank 65ltrs
Cruising range @ 2300rpm 165nm or 32.5hrs
cruising speed 5knts
Engine Nanni diesel 21hp new 2010
burning 2ltrs p/h
3 blade fixed prop


Or do you even know?
Im interested in your results if you know them as i spent this weekend working out mine.
Maybe i was too lazy in the past because i never went too far afield but i was curious to see what the consumption was, and giving my 3 blade fixed prop, its very close to the engine manufacturers estimated consumption on the manual.

Mine in very rough figures and imperial is:

heavy displacement long keel £2 ft Barbary ketch motor sailor

twin 40 gal tanks

45 HP vetus 5 years old

a cross channel motor uses about 10 gals needles to cherbourg so 60 miles so 6 mpg

240 miles per tank, 480 total, perhaps nearer 500 when I worked it out more accurately

BUT:

would you use all your fuel?

I work on using the top half of my tanks so I always have plenty in reserve: If I motored x channel then for some reason had to turn round before being able to refuel, I could get back home!

For example I was once stuck in alderney for days in fog and they were runing short of diesel ashore cos the supply tanker wouldn`t enter braye and i could see a window to skoot back home.

Also I dont want to suck up any crud from the bottom and also I like to keep the tanks fairly well topped up to reduces condensation and all that follows from that, so I would take your maximum range and halve it for prudent cruising

Well, we've motored for two and a half days non-stop, but we did carry some fuel in cans. Tank is 45 litres (I think) and we usually carry 40l when on a long trip, and I reckon we get something a bit less than 1 l/hr at 5kts so 85 litres @ 1.2l/hr =70 hours, or round about three days or 350 miles.

Merc 40hp engine...
3 litres per hour (approx)
150 litres in tank

that gives 50 hrs on engine, at 5 knots = 250 miles

Fuel consumption

In the 13 years I've owned my current boat I've so far used 1126.6 litres of diesel in 973.7 hours of engine running, giving 1.157 l/h. My main tank holds 50 l and I carry 2 10 l bottles, so my expected total endurance would be 60.5 h and at 5.5 kn a range of about 333 miles.

Obviously, as others have said, I don't check to see if I could manage this in practice.

[snowleopard]

7 mpg at 8.5 knots. About twice that at 5 knots on one engine - I can just about manage 1000 miles with 2 x 140 litre tanks.

Range 70 hrs

 

[Pinnacle]

Benny 411
Volvo D2 55hp
Volvo folding prop
Tank is 150 litres
Consumption at 2000rpm approx 5 l per hr
Endurance therefore 30hrs
Max distance therefore approx 210mls ( ish )

We do carry a small amount spare on board in cans.

EDIT According to Mr Volvo ( see below ), consumption ought to be about 4 l per hr at 2000. So that would suggest
Endurance 37.5 hrs
Max distance therefore approx 262mls ( ish )

Thats good economy!

I zero an hours run trip meter every time I fill up and record the hours and fuel used, my consumption ranges from 2 ltrs / hr in economy mode at about 4.5 knots to 3 ltrs / hr at about 5.5 knots.
I have never run at full thrutch for long enough to get meaningful figure for that.
With the 212 ltr tank I can get from 70 to 100 hrs or 380 to 450 miles (maybe even 500 miles if I use my 20 ltr reserve can).

PS - When the hull is clean it is better
