Uh, about precession still, and I'm probably a bit lost with the terms and therefore should stop digging deeper, I see two things mentioned here: 1) gyro (stabilizing) effect of spinning crankshafts and 2) gyroscopic precession and it's effect on boat's direction when the boat is pitching in waves? The first of which is not dependent on the direction the crankshaft is spinning while the second would be cancelled out by the crankshafts if they were spinning in different directions.
But as the discussion on the whole was about precession, the point no. 1 (and my earlier comment) is not relevant here.
Merry New Year everyone all the same!

Yes, I'm glad you spotted my joke (following the 80's movie 'Trading Places').

They are not two separate things though. They are the same, or at least they are joined at the hip. There is no such thing as item 1 unless you allow item 2 to happen, ie you must allow the spinning object to precess in order for it to have the stabilisation effect.
I watched Trading Places the other day btw. UK TV digs out old movies at christmas. Wow it felt old! J L-C was nice though

Here's a very quick build update. I'll try to get to factory week after next maybe to get some more info
This is the hull, now with all internal bulkheads in, and the saloon/dining/galley floor moulding in. Very soon the deck/top half moulding will be attached. The silver-grey lump to the right of the shot in the distance, above the plywood staircase thing, is the special flybridge dashboard being made on the dashboard bench. To the left of the shot you can see they are starting hull fit out on the next boat in line - they sold several sq78s to end customers just before Christmas so the line is pretty much sold out for 2013 deliveries now and looks set to reach 100+ builds (mine is #92)
Engines and all engine room machinery are in. The position of the Cat engine display panels seems to have turned out ok - the second pic below is the view as you open the engine room door. The exhaust risers (which connect where those yellow round blanks in the turbos are) might obscure the displays a bit but I think they'll be ok
This last pic is a bit geeky - it's of the aft starboard quarter and shows the custom black tank system unique to this boat. Having lived with Match 1 for 1.5 years I reckoned there was room for improvement so Match2 is quite different in the black tank department. The materials are different; the pipe runs are different; and I have only 2 black tanks not three as on a standard Sq78. I'll make a post in detail sometime to share ideas on this. The black piping is special steel-reinf butyl rubber lined stuff, which is better than the smooth white stuff that boat builders usually use. It is the grey/white piping in this picture. The blue pipe is fresh water. Also in this pic (above the grey, below the blue, middle of pic) you can see the exhaust by-pass plumbing, which links with the discussion on Jonmendez's thread about Sorebro exhausts

Interesting post on your black tank design.
What kind of level sensing are you using? No moving parts I trust, otherwise I fear you may need to use those two access hatches - rather you than me
And what is the yellow hose? Is that a breather?

Looks great JFM.
You could get a 'jump seat' fitted rearward facing so you can sit in the engine room whilst at sea watching the cat displays. Probably knock up a bracket off one of those engine mounts for it. Might need ear defenders though.

Quick explanation of Match2 black tank thinking. This is a v v v quick summary of a topic that has had lots of design and research time, becuase as ever with boats a simple idea in concept is quite difficult to implement in practice esp when you have to meet all the regulatory requirements as well as fix the engineering issues. Anyway :
1. Std s78 has 3x black tanks, 3x discharge pumps. One forward in the V of the hullm, with port and stbd guest heads going to it. One in master cabin, for master cabin heads. One aft starboard quarter, small, just for crew WC
2. I didn't like the master cabin set up. As you lie in bed, facing forward, you have the WC behind you to your right. The white poo hose comes from here forward, then across the foot of the bed starboard to port, to a black tank at foot of bed. Then a discharge pipe comes from the tank down aftwards to your left, to a disch seacock. Don't ask me "why" to any of that - it's hoe they've always done it. So as you lie in bed you are literally surrounded in poo pipe. Now, that white poo pipe makes all sorts of claims about keeping smells out but in the warm med it aint true: molecules of smell get through the walls
3. So I have jetissoned the master cabin black tank completely. The poo pipe fromt he master WC goes down from WC and aft through the engine room bulkhead in stainless steel pipe. Inside the e/room it switches to buytly pipe and runs aft to the tank in the picture above.
4. In the pic above, there are two tanks. Front one is fresh water, aft one is black. Normally in sq78 the aft tank (black) is small and the forward (freshwater tank) is large. I have however had 2 special tanks fitted, a 200litres bigger black tank and a 200 litres smaller water tank. My master cabin WC and crew WC use this aft tank
5. Upshot of all this is, i have 200 litres less freshwater (so I'm down to 800litre, but my w/maker does 280/hour so i couldn't care less) and I have eliminated a whole black tank system under the master cabin. I've also eliminated a pump and a 1.5inch seacock, which is nice. I know for sure i cannot now have any "tanky smell" in master cabin because i have virtually zero black plumbing under the master cabin
6. I didn't alter the design of the forward black tank becuase this worked fine. However I have specced the special pipe for it, and everywhere else
I don't know, but I'm hoping this will all work well. To answer your Qs, yellow and blue are breather/filler for freshwater. All the black tank piping, incl breather, is in grey. And I'm using dometic TankMaster level sensors - I have had these for 8 years on 3 previous boats and I like them - always work well in my experience and require almost no maintenance. They have 3 polo-mint shaped floating probes that slide loosely up and down 3 sticks, operating 4 indicator lights
Wakeup, good plan, will do
. (Actually as you look at those screens you are forward facing - sorry if pictures are confusing). I could just put a window in the e/room door if someone makes a retrofittable suitably fire proof or whatever window panel...

What's the special pipe called? I have some re-plumbing coming up on my new saily-boat, and I'm sure whatever Match 2 uses will be suitable for me. Find it mildly amusing to have one small thing in common, in fact

That seems like a very good modification. It's much much nicer to have all the poo as far away as possible.
The s/s run from the toilet seat to the bulkhead is probably very short but as the flooring and the bulkhead are separate structural elements (as far as I can tell), is there any possibility of even a minor movement between the two so that a rigid part connecting them could cause problems? Or is there some sort of dampening in the fittings?

It is interesting that while there are 90 odd Sq 78's out there, of which probably 50% are on the Med or other suitably warm place, why hasn't Fairline changed the std design? Or was the aroma issue in the Master cabin peculiar to M1?

Yes, and with any luck the view of those two beautiful white 3 tonne machines from South Carolina might cause him to reflect on the fact that props don't move boats. At least not all on their own...Somewhere for Latestarter to sit whilst sizing your props and monitoring WOT power band
