Anyone notice that the boat tests in the 'new improved' MBY no longer quote nautical miles per gallon in their boat tests? Instead they are now quoting litres/hour which personally I find a particularly useless figure for cruise planning purposes and litres per nautical mile which is a bit too European for me

Does anyone on here calculate the fuel consumption of their car as litres per km or litres per 100km (except for our European friends)? No I didnt think so. We all think in terms of miles per gallon. So MBY bring back nautical miles per gallon for boats please;)
 
It’s because they simply quote what they see on the dash at various rpm along with knots from the gps .
What’s not to like ?
You have a hr meter too and presume acces to a watch / clock , so it’s pretty easy to calc if you want your fuel burn .
Time in hours x L/ r .

Further more for planning as well as a rough ish idea of the distance , say Antibes Calvi approx 100 miles , most plotters , well mine within a few mins of leaving the home port take 1 min to set up .
Then it tells me time Tgt and counts down as we go along so I know before wife has stored the fenders exactly how much fuel it’s gonna use .
Luckily for me the plotter is on the far LHS of the dash and she perches on the RHS :) so I don’t both her with the fuel useage .

Actually my preference is inches on the tanks sight glasses .
You can see the total L of the glass it’s graduated and note how many inches it drops / day .
I use this for routine running around .
So a rtn trip from La Nap to Antibes is about an inch .
Typical day to the islands bit less than an inch .
From that I can work out how many days usage before we need to visit the fuel pontoon .

Not only Europe does litres per 100 kilometres and litres per hour (boat), Oz also has been that way for a couple of decades now...you will get used to it Mike :).
Besides the quantity difference between American and UK gallons may also be a factor.

I actually like using MPG, when I'm driving in the US.
Being used to Km/l, it makes me feel like their cars are amazingly fuel efficient! :rolleyes: :p
 
Come on guys, you didn't get where you are now without learning basic mental arithmetic at school, did you! Dividing by 4.54 = 0.22. So 100 litres x approx 2/9 is easy. Divide by 9 first (easy way = add 10 percent then divide by 10), then double = 22 gallons, near enough for me. Anyway you buy and refill your tanks in litres so why bother with the extra calcs, apart from keeping your brain exercised, but I'm sure there are better ways to do that.

The thing is, does anyone use MPG for cars to calculate fuel requirements for a journey or just use it as a comparative measure of efficiency? Most that are concerned will know how far they can go on a tankful and how much it costs to refill ,but thats not quite the same.
 
Coming from a metric system I still havent come to grips with the imperial system and I've been immersed in it for over 20 years. Forget just fuel. It's tools too. Twice as many spanners, sockets, allen keys etc and dont even begin to get me started on blasted thread sizes. Metric please. Metric all the way!

Mpg good litres per mile better for me. Any which way distance not time needs to be there for it to be useful for me.

Your adjustable fits all thread sizes

Yikes, the worst tool in the toolbox, only to be used as a last resort and if possible not even then :)

How old fashioned. A quality adjustable is invaluable. Yes, a socket set or spanner set is essential and first choice but an adjustable will double for any size and sizes you don’t have. Get yourself a couple of Bacho’s.

As to the original question, I use litres per hour as the distance you go in one hour at a given rpm will vary greatly depending on conditions. I always know how many hours I’ve used and have left. As in the Metric thread, I use both metric and imperial.

No matter what make of adjustable, seriously, why the hell would anyone grab a nut or bolthead just on two sides when you can get it on all six? Buy all the spanners and sockets you need, they're not exactly dear, then you can be confident that your'e using the right tool for the job and not making more work for yourself in the future by rounding any corners off.
