There really isn't a thread for general things Imoca 60's, and most people don't like to go to the Shorthanded forum anyway. So here you go, for your proper ocean racing imoca stuff, if you like.

The following video is as much about the lovely Pip Hare and her Vendee efforts as about the Fastnet, so fits very well in here.

About time someone did this. So annoying to have to go to Short Handed for one thing then back to the Ocean for another.! :P

We do get along and we are not arguing with the shorthanders at all.

The problem is that the individual threads for the boats, and those for each race, are all in this Ocean Racing forum. So it makes sense to have a general imoca thread here as well.

And then there is the additional problem that the TOR imoca's are not shorthanded, so they certainly belong here. There will be splits, and that can be a good thing to keep it organized, but they should all be in this forum IMHO..

Boris Herrmann embarks Greta Thunberg on Malizia for a crossing of the Atlantic to New York
The IMOCA Malizia II, helmed by Pierre Casiraghi and Boris Herrmann, will welcome the young Swede Greta Thunberg on board for a crossing of the Atlantic. Before participating in the United Nations Climate Summit in New York on 23 September, the girl chose to sail with Team Malizia to cross the Atlantic from England.

Departure tomorrow Wednesday
Boris Herrmann: " I am delighted that our sporting ambition and our sailing project can play a role in raising awareness of the most important challenge facing humanity today. I feel honored that Greta has accepted our proposal to cross the Atlantic aboard Malizia, despite the lack of comfort for her. »

Thanks for that, jb5 !

For a bit more on Boris Hermann, his Malizia, and his climate action, see his website:  https://www.borisherrmannracing.com/press-releases/sailing-team-malizia-joins-the-un-initiative-sports-for-climate-action/

This is also going to fit in well with the TOR's sustainability program.

I see the SA forum is all over this today. No carbon footprint.... A boat made of carbon and that one also should still have a diesel installed.

Publicity stunt. 

Sorry but really no idea how that relates to sustainability either. Marketing pitch aside.

TBF to all those involved - Malizia/Boris/Monaco Yacht Club's entire focus is marketing/publicity anyway so if he's going to have to cross the Atlantic to get to the start line of an IMOCA event, what's the big deal with bringing along a kid and her dad?

That "kid" as you call her, has a tattoo on her back showing where DRY LAND IS!  Seriously though, there are certainly more comfortable sailboats for non-sailors to go transAt than an IMOCA.  I'm sure they are routing the smoothest E to W transatlantic route for them.  Otherwise they may never want to go sailing again.

The whole thing's about publicity, don't have a problem with that.  She has a valid message even if she's a bit wacked out and in reality her boat, like any big carbon race boat, is an environmental disaster.

Are you sure?

Those videos are heavily edited, and I am not sure that we can (from our comfortable armchair) really assess the dynamic behavior of the boat. If you look closely, there is not one "scene" in that video that lasts more than 3 seconds.

I would like to see one uninterrupted scene of 15-20 seconds of the boat flying or skimming above water...

Each time the bow starts to raise seriously high, the picture cuts, and we get to another scene... They may have crashed 10 times while filming this video, we would not know it...

I sincerely hope you are right; but I am getting suspicious of this type of video; it is more a promotional tool than a boat improvement/assessment tool.

Some of those foils on the older boats seem to be pretty compromised due to costs and structure.  I wonder why they did it in some cases, esp with boats 3 generations old now. Initiatives Coeur and PRB seem the only exceptions.  Maybe its good for the class as it keeps some older boats in play. I wish the new boats had rudder T foils.

There's so much fucking green washing going on with other than IC vehicles. It's a joke.

Take the hydrogen crap for example - billed as ZERO emissions. And EV's too - depending on how the electricity is generated. For example. burning brown coal is a 'shitty' way to power EV's. But if fuel generation (including hydrogen) doesn't support the green house gas dogma, it's best ignored altogether it seems.

Apivia and Arkea both look the goods so far in the short video footage of both however it looked like Apivia was foiling easier, although that's just a guess. Early days obviously with the foils being version 1. Can't wait to see the Boss sailing.  (Video footage in Short Handed Thread)

Just start by not buying crap cars and use them till they are finished.

I am in my mid 40s, I've owned 3 cars and all were doing 40mpg or more. Good 1990s cars were doing 40mpg.

I've often wondered about that as well and read some somewhat 'blue sky' analysis that fail to capture most of the variables..  I've read that they plan to recycle the batteries but then most of these cars are still too new to be in that range yet.  Will some of these manufactures even be around when the time comes to recycle and how many owners will follow the process given that there is one defined somewhere.  most new luxury cars are turned over within 3 years around here so original owner intents are mostly meaningless.  how many end up in land fill after crashes right now. i think with the huge number of variables involved there will be very little in it either way. Marketing BS. reminds me of multi year pay back schemes companies try to push so you buy their products/services. payback cannot be accurately measured, there are way too many changing variables and circumstances

Add in to the mix that most normal cars use steel and aluminium predominantly for the structure, which is easily recycled and electric cars are more weight sensitive so use composites and plastics more, which are not so easy to recycle and the batteries aren’t the only issue.

Dead Rabbit started another new thread with this link: 

 

another video in flat water with good breeze on a reach. We need to see some more than ideal conditions to really see how well these things work. 

Upwind in light airs will be interesting for TOR and any angle in a big sea state as well.

I wonder if this boat will ever be part of the TOR.  Somehow I doubt it. 

Really nice looking boat.  The Macif sailing empire keeps turning them out.

We should be seeing all the TJV promo videos coming out soon.  Really a very good idea to try to keep all things IMOCA centralized here, no need for a thread for each boat.  Same with Ultim.

If Thomas can get enough funding in time I would think he will be a player.  The boat looks great.

Sebastien Simon interview. Arkea Paprec. Well worth reading but in French of course and too long to copy a auto translation here. Some interesting views on hull and foil shape and power and the different approaches of the designers of the new boats.

He also talks about enclosed cockpits due to speeds expected although his boat is currently pretty open. They also consider the upwind performance gap to  boats with straight boards to be much smaller or even closed.

Otherwise he won't get out of the North Atlantic before that one snaps off, from carbon fatigue!

is a high quality carbon laminate that is sound and has some flex built going fatigue like metal? I still think there's some pretty good flex happening on that immersed foil.

That I don't know, 321. Airbus' new long range A350 jet has fuselage and wings made from carbon fibre apparently, so I hope so. Plenty of flexing going on there one would imagine.

I recall seeing some video footage of the old Hugo Boss ripping along on a broad reach, with her leeward foil tip bobbing up and down none-stop - so there must have been a hell of a lot of flexing in the foil.

It depends. Even with metal fatigue is a different process depending on alloy type. You build a bicycle out of aluminium and if the tubing diameter is too narrow and the frame flexes - a human who rides hard can break a frame. Built it out of cromoly steel and the tubing diameter can be narrow and wet as a noodle and functionally the frame will never fail from fatigue cycling with a human riding it.

One of the more extreme visible flex you'll likely see are in 787 wings or gliders with extremely high glide ratios. There's nothing inherently wrong with flex as long as they stay within design parameters. With the loads they're putting on the foil - nothing is really without flex.

I've put thousands of hard miles over the years on at least 6-7 aluminum bike frames. good frames, stiff and fast until the inevitable fatigue crack shows up one day, and usually around the bottom bracket in my experience. are you a cyclist/MTB'er?

We flex carbon dinghy masts a lot and it doesn't seem to bother them.  Provided these things are designed and built properly I don't see an issue.

agreed. the integrity of a carbon part is completely reliant on it's manufacturing quality.

I'd guess it's probably safe to say these 60 foils can indefinitely flex significantly without failing. that must simplify matters immensely.

Yep - in another life had some development work with fluidforming with a large taiwanese HQed company that wanted to push the limit of aluminium frames before carbon composites really became more mass market. Same company also ended up making some of the best monocoque composite frames because they wanted to go all out & invested heavily on molds and composite looms while other European & American firms were trying to "bridge the difference" with lugged headtube, bottom bracket, seatstay/top tube assemblies.

Nope - 2008 was much later than when we were involved. More involved with the company in late 1990-2000 on TCR frames and ONCE & dealing with UCI. 

Also was nice because they continuously improved and also didn't cut corners. Good engineering good manufacturer. Hence why by the mid-2000s their book of OEM business for other big brands was nearly larger than their own name brand. They could build mid tier frames at much higher quality and no more expensive.

Production line was configured like a Japanese automotive line, safe, and didn't work people to death.

Also understood how to invest in the PRC offshoring properly - OEM alloy frames production got big off there. Keeping high end composite, R&D, marketing at home.

I've had two aluminum TCR's and currently ride a carbon TCR that is a frankenstein build from a frame set. it's a sweet bike.

That's part of the design process, a part will be designed to hold a given number of cycles, 10^7 cycles often being considered as infinite life as the strength of the material will not evolve much afterwards. Other parameters to take into account are anything that will impact the strength of the material or produce local stress concentration (wear, corrosion, cracks, ...). As Imoca designer don't want to consider the worst case scenario as it would lead to over-weight, they probably accept a certain risk factor.

The most tricky in this process is to obtain good values for the material used. It takes a lot of testing and testing time to produce good values as multiple samples needs to be tested at different stages of the life cycle to produce a relatively good fatigue curve (something like the one below). While it has to be done to qualify a given material in the aeronautics industry, there is no such constrain for boat builders and I wonder how much is based on actual data and how much is based on literature value and real-life experience from previous design.

As they will push the limit, some foils will probably break during the next VG. Not sure anyone sensible is expecting the fleet to come back with all foils intacts.

The trouble with aluminium is that there is no safe load where it doesn't propagate cracks. Which is its dark secret. Most other metals you can reason about when cracks grow or not. But aluminium has a use by date that is baked in. (This worries me with the rise of aluminium in car construction. There are good reasons why Jaguar bond and weld their aluminium cars, and don't bolt them. Holes are the enemy. The cars won't rust, which means they may last a very long time - where cracks might become the dominant failure - which isn't a happy thought if you own one.)

Carbon of course is nastier in some ways. More complex to design and reason about the fatigue life, and subject to sudden catastrophic failure when it does let go. But silly strong when you get it right.

Always had a soft spot for steel tube bikes. There was probably a bit more mileage in the technology, but carbon killed them off. But carbon bikes have a use by date as well, which steel didn't. (I still have a vintage Reynolds 531 framed road bike.)

There are a series of short videos and photos in the IG post. Can't find them elsewhere. They are doing speed runs and the noise level is huge. Looks like fun.

Sailing is clean sort of....

Google translation.

The IMOCA class and its riders commit themselves to sustainable development
Major support of the Call for a "Common Ocean of Humanity" and signatory of the commitment letter "Sports for Climate Action", the IMOCA class has set up its own "Oceans Program", proposing concrete actions . Overview of actions taken by the class, runners and organizers, in favor of sustainable development.

"Oceans Program", an action plan 
Sailors are the first witnesses of the global impact of man on this essential and fragile environment. The time is no longer in the report, but in action. This is why the IMOCA class is setting up an "Oceans Program" to reduce the impact of projects and to disseminate positive and positive messages. The action plan is based on four themes (events, ecological transition, awareness and science).


IMOCA continues to support the Ocean As Common program
The IMOCA class is a support from the first hour of the Call for an "Ocean, common good of Humanity", launched on June 8, 2018 during the Monaco Globe Series. To formalize this partnership, the Class signed a sponsorship agreement with Ocean As Common one year later, in order to support its message and accompany its actions during IMOCA events.


The signatory class of the UN Charter "Sports For Climate Action"
IMOCA is one of the sports organizations that has joined a new climate movement in the world of sport. The signatories of the Sports For Climate Action Charter commit to adhere to a set of five principles and integrate them into their strategies:

Undertake systematic efforts to promote greater environmental responsibility
Reduce the global climate impact
Educate to action climate
Promote sustainable and responsible consumption
Advocate for climate action through communication.

With aluminium alloy structures, the key is to over engineer the structural stiffness so the # of cycles to failure is as high as possible & build in defect detection before catastrophic failure.With the extremely stiff space frames being used on luxury/sports cars with relatively few expected miles - prob safe to say they'll last longer than any of the electronic and wearing components will & be safe in a garage somewhere.

More monster foils and other updates on the old Safran (the non foiling one).

Translation by Google.

IMOCA MACSF relaunched after a major construction project, Isabelle Joschke: "I'm going to have the chance to fly on the water!"
After several months of construction, MACSF was launched last Thursday, August 29 in Lorient. The IMOCA has been totally transformed to be faster but also better adapted to its skipper Isabelle Joschke. "Apart from the hull, the whole structure has been revised to allow it to be more efficient. With its foils, it will have strong accelerations and decelerations. Its speed will be faster but also less stable. I will discover new sensations: I will have the chance to fly on the water! "

"Up to 30% faster"
It is indeed a real refurbishment that knew the boat (former Safran Marc Guillemot) with 5 major modifications: foils, mast, cap, electronics and sails. "The changes on the IMOCA MACSF make it more manoeuvrable and increase its speed potential. It can be up to 30% faster in optimal sailing conditions. We are looking forward to seeing his performances in the race! " Says Alain Gautier, team manager of the Voile MACSF project.


Adding foils
The straight fins were replaced by foils, which required to review the entire structure of the monohull. Objective: to gain power and speed.


New wing mast
A new wing mast has been installed. Its more aerodynamic profile and the possibility to orientate itself according to the wind direction improve the performance of the mainsail. This wing mast required modifying the anchoring of the stays at the deck and the internal structure of the boat.


New roof cap
To bring more comfort to the helm and better visibility, the IMOCA MACSF has been equipped with a new coach hat. The maneuvering area is thus better protected and the specific layout of the cockpit is more adapted to Isabelle Joschke's physiognomy.

An electronic check-up of navigation instruments was also conducted and the autopilot was changed.

The anchors of the forward sails on the deck have been modified to account for changes to the monohull and improve overall performance.


Training with Morgan Lagravière
Isabelle Joschke will now proceed to some sailing to discover the IMOCA MACSF before starting an intensive double training with Morgan Lagravière. He will be his team-mate for the Azimut Challenge from September 18th to 22nd in Lorient, then for the Transat Jacques Vabre, which will leave Le Havre on October 27th.

Check out the American Factory movie on Netflix, if you have it.  Its about this very subject.

Some Apivia shots. Enclosed cockpit so steering outside the door. Looks like Yann Elies. Got to wonder how these cockpits are going to work out. Not much head clearance either. Hit a wave, hit your head. Probably to sore too be funny. Not like these boats don't crash down all the time. 

And this is just outright impressive. 

Elise is the rigger.

Koiro Shiraishi's new boat.  VLVP. Sister ship of Charal. Launching Monday.

The 60 feet was out of the Multiplast yard this Saturday in Vannes.

Kojiro Shiraishi: "It is a great honor to have built our boat at Multiplast. Great names of sailing and famous boats have passed through this shipyard which has always been for me a symbol of success in offshore racing. Before visiting Multiplast's premises, I thought that there was surely a superb workforce with exceptional know-how working in a very professional way. I was not disappointed and I thank all the team at Multiplast for building our beautiful boat. "

if I could do any work in the industry, it'd be as a rigger. I love the combination of high tech and old world methods that are used today.

Interesting video on the link if it works. Apivia and Arkea. Some great images some of which are not new. Dialog in French and I haven't a hope of translating it.
