Hoping to bring Boomerang from Milford Haven to Skerries next week, leaving Friday 26th.
She has a Yanmar YSB12 engine that has just been serviced.

Does anyone know how much fuel she would use per hour?

My plan is to allow 2 litres per hour as I think she should probably use about 1/1.5 l/hr at 5knts. Anyone agree/disagree?

YSE s are known to be economical .. Mine seems to be good . I think you are right ,, I ran out of diesel when about to move to the crane!
refillrd but reluctant to start when opened the 1\2 Small bleed screw .
I slackened the 17mm injector pipe swug over a bit retightened and she went . immediatly.
Get your diesel from a garage not a super market ..
Super markets have cheap diesel with out the additives .
YSEs need all the oily bits left in ..
My mates BMW runs like a pig on super market diesel but is great on garage stuff .. He was told by BMW to use the dearer stuff.

Thanks Ron,
She has been run on red diesel from the marina up to now. I was just going to fill her up at the marina and take some spare cans. The original fuel tank has been replaced by a 40+ litre plastic tank, like an outboard one. see photo

My 9 metre is not a true comparison as it has a Yanmar 1GM10. Uses about a litre an hour at 5 knots. Will do 6 at a push in calm water but consumption goes up quite a bit. So I guess 2 litres is about right if the bottom is clean.

My nanni 2.10 10hp uses 1 litre per hour cruising at 5 knots and 2 litres per hour flat out at 6 knots. I go at 5 knots!, 4 knots is about 1/2 litre per hour. Makes a big difference for little speed gain, 1 litre will cover 3 nm at 6 kn, 5 nm at 5kn and 8nm at 4 kn.

We have a Sole diesel so not much of a comparison but would recon 2L per hour is plenty as long as you don't gun it for hours on end. Good luck with the crossing.

Thanks for all the input, guys.
I'll go with the 2 litres per hour and a reserve tank too!

Weather looks Ok for the trip at the moment but the winds are NW or N so there may be a lot of motoring. May change by Friday.........

Fingers crossed

It will be warmer than your last trip, According to the forecast this evening it's to get cooler with showers for the weekend, so not too bad.
