Leither The member may be retired, but it is still more than capable of going into action!

Being a responsible forumite, I will, of course, spare you the details.

RAGTIMEDON yes, I know it's off the subject but I just noticed that Leither has a retired member --they've got a pill for that!

2.) Engine compartment not vapour proof to the accomodation spaces.
3.) Non-ignition proof battery (auto type)chargers in the fuel/engine
4.) AC outlets in the fuel/engine compartment.
5.) Ungrounded fuel fill/tank.

Actual selling price of a diesel vs. gas in this category is usually 2-4k more.

Ahhhh ! diesel fumes ....mothers milk
Gee Boatpoker, it sounds like you are describing my boat! Almost exactly what you said when you surveyed it!! You forgot to mention the battery tiedowns, and waited for another post to mention the household ac wiring and ac fuse panel.

meuritt Having just read the current issue of Good Old Boat and the article about the A4, I was very curious to read this thread. Of course, it turned into gas vs diesel. Too bad. I happen to like gas, and wooden boats, but the boat that fit my dreams was glass with a diesel, far too big a boat for a single A4, maybe twins? Oh, don't like twins, sorry, its a motorsailor for me.

Boat Poker, I am with you, having just bought a boat and looking at a couple dozen, probably more in the last two years, the number of boats still afloat that seem like they shouldn't amazes me, from rot to bad engine or shore power installations.

Long live the simplicity of the A4, close up the cabin, and vent before refueling and, of course starting

Leither I came across this post by accident while looking for something else (the thread has been so riveting that I can't remember what it was....). My experience in the UK (and in Europe as a whole) was that diesels are all but universal on sailboats ovee there (outboards being the exception). The reasons for this are as so clearly set out by Boatpoker ie safer, more reliable, more economical in terms of fuel consumption. Let's face it, the initial cost question is really only an issue if replacement is being considered.

However, if I was in a position where I had a gas engine which I knew well and which had always been in the boat, I would sure be tempted to have it overhauled. Somehow, it seems the right thing to do.....

djodenda Perhaps we can all concede that "boatpoker" is a good login name for a marine surveyor?

boatpoker Safer, longer lived and more reliable. I concede defeat.

sailingdog If the two engines got the same gallons-per-mile... the gasoline engine would still be far less expensive, both initially, since diesel engines are generally more costly than gasoline ones, and over the long term, since the gasoline prices are generally considerably lower than the diesel ones. It takes a lot of miles to make up the price difference between a diesel installation and a gasoline one.

Please note, I never said that diesel wasn't better suited for power boats under certain conditions... however, for smaller sailboats, diesel really doesn't make much sense... you're beating a dead horse, and you've lost the argument already, but just can't seem to face the fact.

sailingdog SemiJim-

You forgot to add that the marine fuel dock price for gasoline is considerably less than that for diesel.

Ideally, since this is a sailboat we're talking about, the increased fuel efficiency of the diesel engine shouldn't matter too much...since I'm generally sailing rather than motoring.
