I'm surprised that's not a BSS fail to be honest, best practice has always been that diesel tanks do not gravity feed an engine but that the fuel has to be lifted out via a stacker pipe. I have no idea how the fuel comes out of the fuel tank. The intake pipe has a shut-off valve (swing handle) to prevent fuel from getting to the engine. I have asked for a similar valve to be put on the out-take pipe (excess fuel flows back into the tank) but was told narrowboats don't usually have them as they are unecessary (but Shire Cruisers' fleet are fitted with them). BSS men seem to have been happy with what we have. In the photo (last page) you can see clearly these in/out pipes and the valve. Of course, the fuel level in the tank is only higher than those pipes when it is (ie. tank full). 3/4 or half a tank means the level will be lower. Desiree has a shut-off valve on the return feed and the BSS examiner did say that this was unusual.

I wouldn't have thought there are three alternators, but without seeing it I have no idea. You do get people who have some funny ideas about how boats should be set up. That's true and to be fair donkey's boat is quite an unusual one with regards to the former owner so now you mention it maybe it does have 3 alternators. I don't think that pulling that much power off the end of the crankshaft would be something engine manufacturers would advocate but at the end of the day once its your engine you can adapt it as you like. I still think it has two not three alts and perhaps donkey was confused.

TW Marine were playing with our engine when they were doing the finishing touches and wondered if it could pull a 70-amp alternator. It did so easily. And we only have a 10hp engine. I'm sure a 42hp engine can run three 50-amp alternators. But, isn't a 50-amp big enough for everything, charging up batteries as you go along in an unhurried and gentle manner? If we had a longer boat, say 72-foot, and lived in it permanently, then perhaps we'd have 4 leisure batteries instead of 2, and a couple of solar panels. Although, looking at 72-foot boats, what would we do with one? They are so unwieldy. But then I could have my own 'den' and the Witch could have her own hidey-hole. And we could have our own toilets.

You'd never get to Gargrave by boat again if you did get a 72ft boat. 60ft is the limit for L@L, but 57ft is your go anywhere length.

There would no reason to run 3 alternators. As an example the Beta marine 90hp (kubota 3.8 diesel) I fitted in my barge in 2011 has a 70a standard alternator and an additional 175a alternator. Sometimes you would get a "travel power" which is basically a DC alternator running through a box of gubbins and coming out via a wotsit to produce washing machine power. I'm sure its a woman thing. Gender issues aside I don't think you would get 3 alternators. I do know for a fact that @donkey boat is quite unusual and I mentioned it to him but I still think it is improbable that it has three alternators. I hope I am wrong as a service person mistaking a coolant circulation pump for an alternator is a bit of a concern.
