Boat in build pics (2013 Fairline Squadron 78)

[intouch1]

while the beolab 5 encore is surely snazzy looking, i personally prefer the universal nature of ipad/ipod control.

my naim musicsrever replicates all covers songlists playlists etc onto my iphone or ipad with ist n-stram or n-serve Software. very cool actually and providing full control.
furthermore, you can connect it to a tv for playback info or stream the Contents from the ipad to the tv.

you might want to make sure if you can Output Video sourced from an ipad through the encore 5 to tv for Picture and to Speakers for Sound.

 

[intouch1]

actually you might want to check the B&O playmaker. it's a Streaming payer that connects to the beolab 3 and is controlled via idevices.

Only just found this thread JFM and congrats on the second of ??? Sq78's. If you recall half way through the build of M1 I teased you that you'd be on Mk2 within a year and you poo pooed me. Tch, told ya.

As before a stunningly detailed post and thanks for it. Only Q I have is what crew do you have? Full or part time or are you a diy'er? And no I'm not applying for the job before you offer, oops, I meant ask.

Thanks for info. Maybe too techie for me - I don't think I want to allocate the brainspace learning how to do all that and setting it up

Yes, video from ipod/iphone/ipad connects to the BeoSound5/B+O TV via a dock and HDMI port (both neatly set in furniture/cabinetry) on Match 1. TV then displays "iPod" on its front source display. On Match2 I plan to dispense with docks but still have HDMI-in socket to the TV (with sound out to the 7.1 system)

Hi Colin. Yup, you was very right. I didn't believe it then but can see now that you are a visionary

Crew = one full time star on the payroll to keep the boat sparkly when on her berth, laundry, receive fuel deliveries all while I'm back in UK. (Turning the boat round after 6 or 8 guests on a long weekend, in 3-4 days, is quite a mission, hence the laundry machinery installed on the boat, central vacuum, etc). When at sea crew varies, but if the boat is busy I would have a chef and stewardess. (chef is hired by the day, not on the full time payroll). If not busy there may be less/no crew on board at sea. No other captain is employed - there would be no fun in that

her phone number is a commodity.

she throws great (weekday) parties

I bet she's a babe too. Life's just so unfair!

Sorry if I've missed this earlier, but are the stabs further back than on Match1?

This must have been covered before and is just my uneducated pondering, but to the untrained eye they seem to be surprisingly vertical. Can their movement be felt in the steering?

They're in exactly the same position as on Match1 Scubaman. Anglewise, the Sq78 hull is a normalish shape and if anything slightly deeper V than others esp the Italian genre of 70-80 footers like say BartW's BA. So they're not unusually vertical.

You couldn't feel them through the steering on Match 1 though inevitably there is a tiny amount of "fighting" between rudders/autopilot and stabs, on a planing boat especially. Long term, we might get systems with the same computer controlling both rudder actuators and stabs

IIRC, we already discussed that, but I'm not sure if we just agreed to disagree, or what.
Anyway, I still can't get my head round the reasons why bother about that type of integration.
If you got some proper explanations from Sleipner - I mean, going beyond common sense alone, and possibly with some numbers on the physics involved - I for one would really be curious to hear them.
To my simple mind, the rudders-induced rolling is bound to be negligible while cruising, and the better stabilization which I accept could be achieved in theory (by anticipating the fins movements) when the boat is being steered, imho brings laughable benefits in practice.
How many times did you have to steer hard over at 30kts, with M1?
Or in your whole boating experience, for that matter...

Ah yes, now that you mention it I rememebr that we did discuss it. I don't remember the ins and outs of the discussion though. I agree the "fighting" between rudders and stabs is tiny (I said so in post above) and therefore the benefit of integrating them on the same computer must also be tiny

TBH, i cannot remember whether Sleipner's idea is to eliminate the fighting between rudder-induced rolling and stabs anti-rolling, or fighting between rudders steering and stabs steering effect.

I'm happy to agree with you that this is pretty marginal/tiny stuff and is way down as item #1000 on things needed to improve a boat

Head of non problems here.

But this is interesting Here goes, the ramblings of a madman. Typed as I think so it may be nonsense!

This is bound to be different at planing and displacement speeds.

Planing. Wind starts from left. Causes boat to turn right. A little bit of lean right but the turn is the bigger impact. Pilot corrects left, thus boat leans left. (this is why planing boats lean into wind) Tabs level boat causing it to turn a bit right. Pilot corrects left causing a bit more left lean. Should damp down to equilibrium if wind stays constant.

Displacement. Wind starts from left. Causes boat to turn right. Pilot corrects left causing boat to lean right - the opposite lean to planing speed, and this adds to the bit of wind induced lean. Tabs have to correct a lot, the lean is greater and the water speed less. Boat comes upright (ie leans left) causing it to turn right. Pilot corrects left causing right lean. Should again damp down to equilibrium if wind stays constant, but bigger lean amplitudes may make it take longer. By which time the wind has changed, a wave has been hit or whatever.

It is clear though that an oscillation (or "fight") between tabs and rudder is possible. Damped by the weight of the boat. But the same computer isn't necessarily the answer.

I already discussed some of this with your sleipner guys but they had got me drunk so it was only half thought out........

The software needs not only to change the amplitude of the tab movement dependant on boat speed, but the reaction time. The latter might be the key.

Plus, the change in these 2 parameters shouldn't be a linear relationship with speed, which is so last year. It should be a curve that is basically a straight line that changes its gradient at the transition to planing.

So when you get to 999 on your snag list give me a call and I'll come back down there and have a play

Guess you'll be on Match 4 by then. Curved walls, high gloss cherry, beige leather, berber carpet...........

I'm going to make a note of that prophecy!

Ok, as long as we agree that the impact of such intergration would be marginal, I suppose it's pointless to expand further.

Otoh, we're on a forum, aren't we...?

I think that your example of wind induced steering and leaning is flawed from the start, because in any condition where the wind is strong enough to create such effects, the stabs have much bigger fishes to fry than correcting such rolling, i.e. stabilizing the waves induced motion, which is waaaay stronger and unrelated to the odd wind gusts.

Besides, if the fins are properly positioned, they shouldn't introduce any steering into the equation.
They don't do that in any even slightly perceivable way in my full D boat, anyway. Possibly, it's even the other way round, i.e. the boat requires less steering corrections when the stabs are on, compared to both the center locked and the freely moving positions.
Otoh, instinctively I would accept that this could be not always true for P boats, because the "optimal/neutral" placement might not be the same at D and P speed, and if this is true the placement is bound to be a compromise of some sort.
But my head begins to hurt if I just try to figure out the implications of all that...

. I might very well be on the wrong end of an excellent bottle of Meursault, oh and a bottle of black muscat, not to mention the g+t and the bloody mary, ah yes a glass of fizz as well (did I mention that I'd been drinking?) ... But this did make me laugh out loud, very funny M, quality.

Back to white caulking. This MB&Y video of a Boarnstream has white caulking. Very nice indeed!

[jfm]

Thanks whopper. On slow connection here, can't view, will do later

Meantime, my hull just came out of mould. Couple of pics below, not great shots becuase the boat in front on the production line is in the way so the cameraman couldn't stand back. When that other boat moves along the line they will get some better pics of my hull. Nice milestone reached anyhow. The next month will involve install of below deck systems like plumbing, as well as stabs, gensets, engines, shafts. And then the internal mouldings (liners) will be glued in

How do they get it out of the mould?

It must split in 2 I guess? Cant lift out there are horizontal bits in those windows. And the bowthruster tube is in. How????

The bowthruster dissects the spray rail too, something I went to great effort to avoid. From that I presume a wasted my time?

 

[jfm]

Nope, it's a one piece mould

The bits that would lock it in - window recess blocks, b/t tunnel formers, some flanges, are not integral to the mould. They are bolted onto the surface of the mould, and "sealed" on using a fillet of white plasticene (some plasticene debris can be seen around the window rectangles in the pic). When lay up is finished these blocks are all just unbolted from the outside of the mould. Then hull is lifted out by crane, and the window recess blocks etc come out too, and are then just prised out of the hull. Easy peasy. The hull probably releases quite easily given that it's #92 from the same mould so the mould has seen a lot of polish/wax over the years

Hope you're not too shocked that they split a spray rail/lift strip with the b/t tunnel!

Just curious, and this really has nothing to do with this thread, but do you know if any boats are built on a male rather than a female mould? Might be impossible but just wondered.
