Offer: true go anywhere Trawler to build "side by side"

Your thoughts are right, BUT...
The vessel will be registered as a commercial, not yacht. There I would have issues in Germany, GB or the like. The "lesser" Flag States like Cayman, offer a tax free status on vessels income, and do´nt care if the income is zero! If that would be the case in Germany, I would loose the commercial status after one or two years.
Cayman moreover offers all the benefits a prime country has to offer.

I do´nt talk substandard Flags like Panama or Liberia.
Did you know for example that the head office of Antigua and Barbuda Register is located in Oldenburg Germany?

Ive never used cayman Flag state before....but does indeed sound comprehensive. So long as the surveyors are up to it.....which i think they are. They offer huge salaries, tax-free...as i know an ex-LR plan approval chap who went there..loves it.

I used to be located near an office of Carnival line, i knew the chief technical manager, ex-LR surveyor (i've meet loads of them in the past 20years). A lot of their ships seem to be registered there, maybe the only reason is because they wanted nice trips to the Caymans to sort out technical "issues"..??

 

Canada Steamship Lines used to be famous for using Liberian, Bahamian and other flag-of-convenience registries.... even on ships that were physically incapable of leaving the Great Lakes. 'Tis all about the money.

Still, there are plenty of nice, small countries with fairly modern laws that will happily register a vessel, and whose flags will garner somewhat more respect when flown off the stern.

Richard, I'm afraid I don't have much to contribute to this thread (your project is well outside my expertise and budget), but I'm following this one with great interest

 

Actually the complete US fleet is registered in Liberia, Marshall islands or Bahama. But that does not make them convenient Flag States for every purpose. Cayman (and other UK territories like the Manx or channel Islands) are seen as UK, and you are protected by British law and British Navy. I once had Georgetown as my homeport it was all to my satisfaction. Cyprus now becomes a alternative, but had a very bad reputation in the past. So I think I´ll fly the Red Ensign again.
The prime classification societies LR, GL, DNV and ABS are all contractors of the MACI and we can find them worldwide. RINA and BV btw. are not considered to be "prime", by many authorities and insurance companies!
Matt, you are very welcome here, and I do´nt think this is out of your expertise, your thoughts above have shown it.

again some anonymus hit me with negative feedback (I cannot identify for what), is that just jealousy? Are there people which cannot stand that others discuss a complex project of a bit higher value in the open thread? sad, really.......sad.

 

Neg rep be damned.

And I have nothing against the Caymans or other reputable territories. There were a lot of eyebrows raised around here, though, when Great Lakes freighters too big to get out the St. Lawrence Seaway to the Atlantic dropped their Canadian flags in favour of Liberian.

I was thinking last night about those friggin' massive 80+ litre diesels that have been mentioned on here. Given that:
1) This is a "go anywhere" boat, and
2) It will apparently be built sturdily enough to run for many decades,

I think it's worth asking questions about the fuel. Will this be an engine that requires clean, clear #2 diesel oil? Or will it be able to handle a bit of variety? I'm not trying to start a political debate, but fuel prices vary greatly from place to place, and some countries are running into shortages or are starting to aggressively push biodiesel and other alternative fuels. If you need to top off the tanks in a country where some kind of biofuel happens to be $1 a litre and petroleum diesel is twice that- a potentially realistic scenario in some places- it would really suck to have to go with the more expensive option.

Also on the fuel note- I seem to recall a brief mention of the fuel system a few pages back, lost in a bit of thread clutter. On a $550,000 powertrain that may have to be fed from sketchy gas docks in out-of-the-way territories, I wonder if one of those Alfa Laval centrifugal fuel cleaners might be worthwhile. At $15k and up they're way too much for my kind of boat, but might be justified on a cruiser like this one.

 

And how much you can contribute, you see?.... thanks for the questions!
Yes this engine can burn ordinary MDO up to 6 centistoke, as well as veggy oil (has to be mixed though). And yes there will be a Alfa Laval fuel centrifuiiiiiiiiii...separator, the left one. They start at 10.000$ btw. that means 5.000€ for a yard, or for me.

I am not sure is because I am getting cold here in Maine, but I have some kind of obsession toward the heating on boat.
So what kind of heating thru out the boat you plan to put: the classic hot water radiator with a oil furnace and circulating pump, or the forced air, or something else?
I had the experience that using the air condioned in reverse to use as a heating works when it's just slightly cold on the morning, but do not work in case of real cold temperature.
The cold come again here, it make me think about that!

Kubola central heater on water circuit. Same circuit is used as chilled water circ. for air conditioning.
Heater is connected to jacket water of main eng. both to heat main before starting and to gain hot water from eng.
The Kubola can burn MDO (if set up for that) a ordinary Diesel heater cannot!
Air ducts in a boat are a mad idea (not for ventilation of course)! They transport noise as good as heat! And they produce massive problems when passing frames (too large diameter).

The kubola is indeed a very good furnace. They are imported here in the West Coast and a lot of yacht use it.
Well thought system.

Nice to see the thread is going ahead on a stable course. The troublemaker is gone.

Good morning Sasha, nice to hear from you.
Yes the thread is back to the subject at hand.

an idea i had was to add a microphone in the engine room to listen to the engine room sounds and a cheap oscilloscope for times you wish quiet, after a while you become adept at recognizing a normal pattern

plus a panning camera

 

That would actually be pretty cool, wardd.... a simple but functional PC-based oscilloscope can be had for $300 or so, some of these have FFT capability. Mount a few microphones and little piezo vibration sensors in key areas of the engine room, and switch your 'scope between them now and then to see if any unusual vibrations or noises have cropped up.... not for everyone, of course, but to an engineering physicist (myself) this screams "way cool".... and a power pan/tilt webcam can be had for $100 or so, also worth having in an unmanned machinery space.

 

The oscilloscope is really a nice idea! The camera mandatory anyway. The mic.s you do´nt need, you hear immediately when the beat goes wrong! After a few days one is so familiar with the "heartbeat" of such engine, one can even tell the rpm pretty exactly. And I will not dampen the "sound" to death (which would be not easy on such a displacement).

 

Some of the 'higher end' engines provide this. We had all sorts of data/telemetry provided on a GT for a ferry we did. vibrations in mm/s vertical and horizontal acc's etc....since the engine wasn't cheap, this cost was peanuts in reality!..was cool watching on sea trails...but after than no one bothered!...of course until a problem occurs, which is where it is great...just print off the data.
