also happens in pro sailing with gear- See Dongfeng in the volvo

[bushsailor 38]

The thing most people do not realize is that the autopilot systems on these boats are completely custom built with no relation to any off the shelf components from any brand.

Therefore it is a smart move from Raymarine to get there name on a boat.

That's my take on what those are for two. Complicated geometry but it looks as if the whole rudder including stock can kick up, another reason for the separate tiller and associated linkage. Pretty simple change in case of breakage too.

It looks like a pretty standard IMOCA kick-up rudder arrangement IMHO

I think that Raymarine and Raytheon are both part of the Navico group, so the guys are probably from someone else in the group.

Just for the record - Raytheon and Raymarine certainly did start out together but parted ways in 2001.  Raytheon is now owned by United Technologies who are a pretty secretive outfit that makes all kinds of military hardware that is mostly aircraft related.  The only brand of theirs that is commonly known is Pratt and Whitney the aircraft engine company.  Raymarine is part of the FLIR group which makes a range of military electronics.

Navico, in addition to the brands that others have mentioned, also make the C Map charting system.  Go back a few years and they were making the Robertson and Northstar ranges.  You can still get parts for both from Simrad dealers.

Stop by my boat sometime and I'll show you a true museum piece - my Raytheon GPS which still works.

Not very secretive at all - just a big conglomerate. Well they also owned Sikorsky helicopters until fairly  recently. Otis Elevators, Kidde (fire extinguishers), Carrier (A/C giant), Collins Aerospace (airplane parts), Chubb Security, etc etc 

[Fiji Bitter 1,158]

Savoir, just for the record, Raytheon and Raymarine did not "start out together".

And Flir does not just make a range of military products.

And BTW, FYI,  the original Navico was a small English company with a very cheap autopilot and instruments.

Raytheon = defense stuff

UTC = Pratt, Otis, Carrier and Collins Aero.  Collins makes lots of stuff for Boeing and Airbus planes, some defense stuff but not much (they also make the hoists that the CG Helo will use if you start sinking......

Otis and Carrier being spun off and then remaining UTC will merge with Raytheon...

and, based on my experience with FLIR, they are super smart engineers, who are involved with a lot of very cool projects and also include some pretty experienced sailors

Same problem exists for the hydro-generators, tough to do if you’re not actually in the water....!

I suppose with a Heat Exchanger cooling system the internal water has a small period where it can sustain cooling until it's exchanged again? The foilers aren't staying out of the water for long although I suspect the new boats plan to so yes good question. Perhaps and increase in cooling water may help? A small raw water reservoir may help in between flight?

The advantage that I see for using a ball joint for that pivot is simplicity. A regular bearing, even a self aligning bearing would require the axle to be at an angle relative to the end of the strut. Totally doable but a ball joint does not require that direction change and is therefor simpler to contsruct. And yes, I can see how it would be easier to thread the balls in or out to make height adjustments, but side to side adjustments would be more difficult. However, the main feature of the ball joint, the several degrees of freedom, is not utilized in this application.

they are out today I am sat on the beach in Seaview and they are blast reaching out  past Bembridge wiht jib and reefed main. Its 20-25kts of wind and wind against tide so they are certainly not holding back. They are about 2 miles away so no pics I am afraid but good to see them out testing hard. As I type it looks like they have paused for lunch as now cruising on main only but still heading out into the Channel proper..... then turn round, jib out and blasted back to Portsmouth!

OK, spare me the "f off newbie"...been here before but had to re-register.

I was lucky enough to get up close to the boat, and I can honestly say any pictures out there so far simply do not even come close to doing it justice.  It's incredible..."porn star" finsh carbon throughout (not black paint as it looks) and just details details details everywhere.  Check out the forward windows on the cabin top and the nav lights built into the stanchions for starters.

And...here are the foils.  They look perfectly "circular" to me and very unlike any of the wide, flat, "Corsair Wing" designs elsewhere.  This thing is an absolute WEAPON and Alex has probably already won the psychological startline battle in this.  It is an incredible machine and I am 100% rooting for Alex this time round!

Good old C boards.  Used on ORMAs, Mod 70s, A-Class and many others.   Proven performance for skimming boats and that is what these boats do.  Cool to see.  

The ability to retract seems like a major plus for light air performance.  Perhaps doesn't give away much in the high speed skimming area.  

Less righting moment lift is needed with the lowered center of effort for the sail.

Everything works together to get easier rather than harder with this design it seems.

Does the sail have a smaller head than some of the other boats?  That would be another sensible step.  The boat is narrower, the boom is lower, the boat has less less form stability, the sail plan doesn't have to have the huge head to get some early heel to reduce wetted surface, the foils have to work less hard so they can be smaller, the sailor can maneuver and trim more easily, the boat is more wave piercing and steady in pitch, etc.  Life is getting easier and quicker!

Looking at the first of Iain’s photos you can see the watertight hatch just inside the canvas covered opening and forward of the main traveller. So no separate cockpit and interior solution, all is now basically inside.

also you can see that all of the sheets come out through the traveller to the transom area then forward to the sails. Logical way to keep things inside dry.

Yep.  It doesn't really show in the photos but the size and design of the door make it look very much like it's going to be closed 99% of the time.  The canvas cover has a zip down either side, but again it strikes me as something that will be closed nearly all of the time.  I'd have expected some kind of "roller blind" arrangement if it was going to be used as some kind of conning position regularly.

It's interesting the way it has all gone.  I've sailed what at the time was Toe In The Water, (formerly Pindar, now Alcatraz IT), one of the much older generation fixed keel boats, but with a very exposed cockpit.  I asked the skipper Steve White "so what was it really like down in the Southern Ocean", and he said "not too sure really, I hardly ever went outside".  It just makes total sense to tuck everything away like this, and spend as much time looking at water flow above deck as water flow under the hull.

[Chimp too 203]

The push to reduce freeboard to reduce unnecessary weight and lower VCG constantly pushes in the direction of a wetter and wetter ride. So as they have done, don't fight it, but make sure that the deck sheds the water as efficiently as possible and that it doesn't slow you down too much. The reverse sheer and dramatically reduced freeboard at the transom helps this even more. After all, water on the deck is an increase in momentary sailing displacement that loads everything up. So get it off as soon as it arrives and don't worry about getting wet by staying inside out of the way.

The sad thing is that even before the first TOR using the IMOCA, the designs of single handed and crewed IMOCA are diverging at an increased rate. This boat really could not be modified to compete in TOR without completely changing the philosophy.

I also note that the C-Foils are tapered at the tips, so could not be fully retracted. The end 1m or so will always be out there. Probably not an issue, but interesting to me. I also hope that they get their real bobstay soon so they can get rid of that make do one.

In that configuration the leeward on will probably acts as a DSS foil and the teeny bit of drag it caused may be offset by the additional righting moment (although this may be irrelevant with a canting keel?)

Either way in the light stuff with presumably a smaller lighter boat, less appendages in the water and less aerodynamic drag, it's still likely to be the quickest boat out there...

I imagine the foil section shape would prevent that but I could be wrong.  Maybe they could just be extended out a little further if the tip broke off given the apparent circular shape?  I would still want a cockpit!

I can’t see the foils being end for ended, but it looks like a symmetrical spare could be a viable option. Perhaps something 50 to 75% in length so it could actually be moved about with a halyard and decent weather window.

should work but the trade is the extra weight if it you do not break one or looking smug if you do but with no cockpit full of water might be ok

Do these foils have a daggerboard section like Maitre Coq foils had? Or what will prevent the boat drifting? The profile of outward C foils near to the hull don’t work against sails sideways force, rather it has the lifting force in the same direction.

If the foils have a symmetrical cross section near the tip then  they could be used mostly retracted upwind so just the mostly vertical part of the board is in the water. In that mode they'd be sailing upwind with the foils loaded on the reverse side of when they're sailing downwind and the package would look pretty similar to the daggerboard boats.

Should work just like any other C boards.  Normally, vertically oriented C boards have area near the tips providing more lift and the area nearer the boat providing leeway resistance.  These are flipped since they are aimed outside.  The primary leeway resistance will come from the tips with more lift coming from the more horizontal forces.

Most fast boats have immersed transoms.  As the boat speeds up, the stern will have dynamic lift. 

For real light air performance, I wonder if Alex has a tank in the bow he can load up to get the stern clear of the water.

 

[Lost in Translation 22]

Looking at Lurker's post made me chuckle as we had different interpretations.  I suppose that is the beauty of the C board.  Depending on the heeling of the boat, different parts of the board do different things.  Roll the boat over enough, and the could be horizontal and purely lifting.

[pilot 21]

Foils probably need to be lowered in light winds. At least it looks from behind that some bigger headsail might not fit over the retracted foil.

Most fast boats have immersed transoms.  As the boat speeds up, the stern will have dynamic lift. 

For real light air performance, I wonder if Alex has a tank in the bow he can load up to get the stern clear of the water.

 

The issue with C-boards aimed outside is that if you're relying on them for both lift and leeway resistance then you've got both pressure and suction on both sides of the board and that is super draggy. It's basically negative endplating.
