How many ways can you Navigate?
If your any kind of Salt you will know more than a half dozen ways. Just wish I could master English Physic navigation. in 7 min works over, drinks are cold, dinks ready, temp is 74, wind is perfect awesome sunset expected...........................

OK, the Flywheel Horsepower of the Yanmar 3YM30 is 29HP at 2800 RPM, while
burning less than a gallon an hour of diesel. That's what the engine manufacturer says in their spec sheet. Fuel economy at WOT will be closer to the "1 gal/16hp" rate, or if you measure propeller output you'll be closer to that number. However, when one talks about "pushing a Benny with a 20hp engine" they really mean running a 2GM20 at 2600 rpm, where its putting out under 8 hp at the prop and burning less than half a gallon an hour. I have 2 2GM20's that consistently use 0.4 gallons each per hour. And besides, the gallons in Britain are 25% bigger. "JAXAshby" wrote in message ... dougies, you idgit.

You're using an aviation turbo diesel to prove your point? That's rich!
If you simply go to the Yanmar site, or the Mastry site you'll find the curves for typical marine diesels. Contrary to your claim, the best efficiency is usually down around 2400 RPM, not at full throttle where the engine's advertised HP rating is taken. The Yanmar 4JH3-HTE your article talks about is rated at 175 grams/hp-hour at full power, which is 18 HP per gallon, but the efficiency goes up to 153 g/hp-h at reduced rpm, which is 21 HP per gallon. Sorry jaxie, the mistake you're making is thinking that marine engines are most efficient at full throttle, or that they are normally run that way.

How much hp is required to push a given displacement sailboat to hullspeed in a given set of conditions? Generally it has been around 2500 rpm in my experience.
