As Zonker pointed much further up thread... water vapor is a diesel combustion byproduct... mixed the other gases is how the corrosion on non-running engine(s) becomes a problem.

Holy hell. Mo action from Jakson. I need not have entertained myself pondering the old exhaust show; we already beat it to death. Reruns do get tiresome. Let's hoist the mainsail on a windy day in the Gulf and see how she moves.
 
That Tulsa fuel tanker plan was not on my radar. Reminds me - I had a friend that would hoard glass beer bottles in WV and eventually load his truck to the gills and drive to MD to get something like 10 cents each for them. Way he drank, added up to quite a sum several decades ago. Worked for him. Dugg's results might vary.

Speaking of circling around, I've pondered his combustion engine exhaust system some more. He has 4 internal combustion engines feeding a common dry exhaust manifold in the engine room. All those engines will have valve overlap wherein near the end of the exhaust stroke the inlet valve will be open. I think the diesel is 6 cylinder, not sure but the generator, welder and scuba air compressor are probably 1 or 2 cylinder each. Anyhow, chances are the diesel might stop with one cylinder having both the ex and in valves open. Say he starts and runs the welder, stands there and does some welding and grinding. The collective manifold is then feeding ex gasses through the main diesel into the engine room. It comes out the diesel air filter. Different scenarios of backfeeding exhaust gas to the engine room are possible such as running the main diesel and having it come through one of the smaller engines that happens to stop with both valves open. Terribly dangerous construct. Carbon monoxide is not your friend.
Interesting thought. I would be curious to know how many of those engines are diesel. In the case that they are all diesel, there would be less valve overlap than a gasoline engine.

Early on one of their concepts was to go but $0.25 a gallon diesel in Venezuela and sail the ship full up to more popular cruising grounds to sell the fuel at a considerable profit, that may have been the cargo he had in mind that caused him to chose to build an origami monohull instead of something more practical for the home builder like a warram.
" Concepts"? Wonder how much further Dugg thought this concept through considering his BSO is hardly built to fuel tanker standards,much less any other reasonable marine standard, and that to proceed with this cockamamie scheme would in all likelihood be in direct violation of a slew of maritime laws,local and international.
Besides, this BSO has passed no regulatory tests whatsoever which would green light any function other than perhaps home made vessel used strictly for personal entertainment and leisure. Even then, insurance would remain an issue since any insurance company would certainly require more then just the builder's word that,"yup she floats and is good ta go!" Offshore coverage would also be dicey and VERY expensive if at all available to such an untested BSO.
It is amazing how he has managed to drag people into sharing his delusions of competence and foresight.

Significant danger is corroding the shit out of the non-running engine by filling with exhaust gases. Every engine installation guide I have read warns about combining exhaust pipes.

Diesels don't make as much CO as a gas engine, but they still do have enough to cause real problems.

What is your evidence of this?

The ship's main engine has the turbo a wee too far from the main engine. You would usually have 3 gensets on a ocean going ship (1 running/1 standby/1 in maintenance). The emergency generator often doesn't have its exhaust up the stack - just out the side of the compartment is good enough for something that is seldom used.

Fairly good effort otherwise.

Yup. 3 generators like I suggested. The schematic is just a general idea, not assumed to be very accurate I think.

someone needs to tell doug to build the sails out of steel sheets. real men dont need no wimpy cloth sails.
nah fabric is fine, afterall think of the engineering that goes into the simple bra, little ones are a doddle but those whoppers take some planning and engineering to contain, all thats required is someone who knows what they're doing............ and no splatton........ I wont show evidence..... leave that to your imagination

I dunno - showing evidence seems like the perfect opportunity for a major DD or DDD (E in England) thread diversion…

…how much battering from this Doug-obsessed thread can the august halls of Cruising Anarchy withstand before the hallowed edifice comes crashing down…before the stout bulwarks of this mighty ship are rent asunder by the multiple breaking waves of bullshit…DD or DDD as a short break, please… :)

Re: Tanker I suspect their plan was to just fly under the radar, as with the rest of seeker there is an abundance of "that'll work until it doesn't" going on.
