I looked thru my 2015 HK catalog on just that point - that's got to be at least a 100mm block? Catalog shows NO units that loop thru the base. Looking at the busted side plate, and the block on the other side, they have a chamfered edge across the bottom hole, but sheave center edge is squared off. I could not fing that profile anywhere in the catalog. Old stock??
I agree with you. The fact that the sheave center hole is not chamferred or rounded off means to me that the loop is NOT supposed to go through. It would be guaranteed premature chaffing...
All above makes perfect sense. However, this picture shows a center hole nicely rounded off...: IMG_5976.PNG

Beyou's penalty decided and met (don't see it on his forss tracks, but the geoville track shows it at 117º W)

Otherwise it has been a night of repairs and making good for certain skippers who took advantage of amenable breezes. Jérémie Beyou (Maître CoQ) made good on a penalty given to him by the International Jury for breaking an engine seal in the Indian Ocean. Beyou was given a segment of ten miles to sail back and forth on for two hours, making no net gain in the course direction, which he fulfilled around 2200hrs. Around the same time some 4000 miles behind him, Fabrice Amedeo (Newrest Matmut) was sailing directly downwind seemingly making a repair to his mainsail which had a large gash in it between the second and third reef. Amedeo is back to course this morning, making 10kts. And Arnaud Boissières (La Mie Câline), who had sailed north to find ideal conditions, was repairing his mainsail track on his mast and making good on a series of other small repairs. Of Beyou's penalty race director Jacques Caraës, who administers and monitors the Jury's decision, explained: “Early in the Indian Ocean, Jérémie fell down and accidentally put his propeller in gear breaking the seal on the engine. He took advantage of some light conditions (5-10 knots of wind) to halt his progress for two hours before setting off again eastwards,” Beyou is advancing slowly this morning as he has entered a transition zone.

Time for a bit of naviguessing towards the finish, post 1/3.

Input

- 0830 CET positions

- GFS 10 days and after that

- Open CPN climate plugin with historical weather data as proxy

- standard IMOCA 2015 polars (thus overestimating performance Alex starboard foil on port tack)

Output

- Armel to finish ETA January 14th see yellow routing

- Alex to finish ETA January 16th see blue routing

- Delta time Alex compared to Armel: 40 hours

- Alex port/SB tack: 37 % / 63 % => could be a worse ratio

- Alex upwind: 49% => not good for catching up with the stub
Thanks Herman. "Naviguessing" is useful now for as a benchmark of Armel's strategy; av. speed will be useful later to compare these new foilers with the old polars. You played around with Remora a bit earlier. Are their polars much different than the ones you use?

Cheers, and a Merry Christmas to you and yours.

Been out of touch lately due to big work deadlines. ALC, around the horn with an 800 km lead, awesome dude! Made my day actually. Family now together (almost) for the holidays. Not so for our heros out there sailing. How do they do it? Love y'all. Be safe and happy. Here's one for y'all.... Cheers.

And for all of you there, be safe and please have a very happy holidays. Merry Christmas! And a Happy Anarchy!

Love y'all,

Varan
Tsk Tsk. Now that you've lobbed a warm fuzzy into the thread, where will the grinches go? :)

Anyway, cheers to you and yours too.

The block that broke is a design that was discontinued in 2009, so the block itself is at least 7 years old but likely even older than that.

 
Some thoughts about the Harken Block debate.

This was a very poor choice of a block for that application even if the working load was respected. This was probably the same set up as the original rigging with just the blocks replaced. Technology has come a long way, and you must use in critical areas blocks that if they fail they do not release the load. Ino-Block is the best for this application. BP is using them in many areas. Karver blocks are very common on the IMOCAs as well

Very interesting interview by Armel Le Cleach, I took the proposed automatic google translate provided by "jonas a" of this Voiles et Voiliers interview and tweaked it for the few mistakes. You will learn that he has not had a single crash jibe so far...

Armel Le Cléac'h: "The Vendée Globe, its wearing you down!"699 miles! It is the abyssal gap this Friday morning in the ranking of 5 O'clock between Banque Populaire in final approach of Cape Horn in a mollifying wind, and Hugo Boss. Armel Le Cléac'h continues to drive the point, whereas Alex Thomson will be more than two days behind when turning the famous rock. Jérémie Beyou (Maître CoQ) clings to his remarkable third place despite the return of Jean-Pierre Dick (StMichel-Virbac), always followed closely by Yann Eliès (Quéguiner Leukemia Espoir) and Jean Le Cam (Finistere Sea Vent) . As for Louis Burton (Bureau Valley), he discreetly pursues his superb course, and runs alongside the ZEA in 7th place. Finally, the big beneficiary of these last days is Eric Bellion (Commeunseulhomme) who, since he crossed the Cape Leeuwin, doubled his opponents one by one. This morning, he sailed in 12th position and founded Alan Roura (La Fabrique) still impressive on his "old" plan Rolland dating from 2000. Third to cross eight years ago, second four years ago, Armel Le Cléac 'H will this time turn Cape Horn largely in the lead this Friday at midday, in a cleanly hallucinating time and five days ahead of the record of François Gabart!


Wednesday, December 21 afternoon, less than 1000 miles from Cape Horn, the Vendee Globe leader gave us a long interview despite difficult weather ... Banque Populaire VIII then sailed port tack downwind in a West North West wind very irregular between 25 and 35 knots and on a strong and crossed sea. Armel Le Cléac'h was preparing for a final jibe in the evening before plunging on the famous "hard cape". You will notice that Armel never says "I" but "We" as if he always spoke of his boat and of him at the same time ... The man is shrewd, modest, does not deliver easily at sea, but he does not evade the questions. If the link was almost perfect, if the sailor was once again of astonishing availability and lucidity, it was nevertheless perceived at the sound of his voice and the surrounding noise that life on board at that moment was frankly very painful ! There was a certain weariness. Armel does not say everything ... but one can read between the lines.

Voilesetvoiliers.com: First of all Armel, how are you?

Armel Le Cléac'h: It's alright, it's okay. It's a little sporty right now, but we do go. The wind is very irregular in strength and the sea is in all directions, and so it is not very simple ... but by this night it should be better. In the South, we live virtually permanently inside. It is like being inside a washing machine, in spinning mode... and after a few weeks, it is getting tiring.

Voilesetvoiliers.com: What about physically?

ALC: Look, it's fine. I do not have too many small cuts and scrapes and bruises apart from my hands that are a bit ruined and make me suffer, and that I try to soothe with cream regularly. I did not have too many physical problems until then despite some good falls in the boat. When the sea is rough, even on all fours you end up bumping right to left, but nothing serious. The hardest part is sleeping in the day when you have conditions like today, where it's hard. I will have to rest a bit to prepare my jibe in the evening. As it is planned from 30 to 35 knots, it will be necessary to be vigilant, to make a beautiful last maneuver before leaving on Cape Horn. Quickly turn left!

Voilesetvoiliers.com: Talking about the jibe, how long does it take, in 30 to 35 knots?

ALC: With or without shifting the gear from one side to the other? (Laughs)

Voilesetvoiliers.com: With ... between the moment you make the decision and the moment you are on the other tack?

ALC: Shifting all the gears, so that everything is clean, you need a good half hour from the time you begin to move the bags and when everything is tidy across the cabin. The jibe maneuver in itself is quite fast: about ten minutes. The jibe is finally quite easy, but then you still have all the sails on the deck to change side ...

Voilesetvoiliers.com: Do you realize that you've been away for 45 days?

ALC: Not really. What is clear is that the pace is fairly sustained. It is difficult to take stock of the past. In fact, the length of the days depends really on the weather conditions, capes to cross, gusts of wind ... Let's say that when the wind is less strong, it helps to better pace the time on board. I did not even know we were at 45 (laughs). You tell me! But good 45 days on these boats, it's not easy, and then 47 days to go from Les Sables D'Olonne to Cape Horn, it's pretty good. Nevertheless, the Vendée wears down the boats and the guys.

Voilesetvoiliers.com: Did the foil breaks of Alex Thomson and then Sébastien Josse prompted you to sail differently? Did you take the foils back into the big sea?

ALC: Yes, but not that much! Me since the start, I was rather conservative about the use of foils, as in the transatlantic races. The difficulty on a Vendée Globe is to find the time when you can sail with or without. And as you never know if you're 100% right or not ... I try to keep these tools for the right angle for the right configuration, when it does not push too much on the boat.For instance, right now, it is downwind VMG in strong wind and sea, and so there is no need to foils. But actually, what happens to others, it cools you down on the moment. You try to understand what happened. What is certain is that when you are a little ahead of your pursuers, you take less risk, you get less annoyed. You put a little more time to do your maneuver, you take another five minutes to release a reef. In short, you go more cool and you try to make it clean. It is a small luxury ...

Voilesetvoiliers.com: You give the impression since the departure of "sparing" your boat, unlike Alex who seems to loar her more?

ALC: Yeah, but we stil have problems on board! There are always tinkers, wear, chaffing, worries of waterproofing ... For now it holds up, but the road is long. I have already done two Vendée Globe and we know that there can be so many things happening. To date, I have not had too strong OFNI causing great damage, and I have had a bit of success unlike some.Keeping my fingers crossed.

Voilesetvoiliers.com: All the competitors say they have crashed jibe. You, have you?

ALC: Look, no! Again, I touch wood! For the moment I have not made a downwind crash jibe. Broaching into the wind, of course, I did, when we were a little on the attack in the descent of the Atlantic (more than 17.5 knots average, ed.)

Voilesetvoiliers.com: And you have not suffered major breakdowns?

ALC: I did. I had an auto pilot problem ... but related to another problem: my heating on board. When I put a little heating in the cabin, a night when it was bad weather outside with 20 knots of wind and rain this caused a drop in electrical voltage. My pilot was going crazy, and the boat was broaching. I did not understand.It lasted ten minutes, and I thought to myself that it would be a big hassle. I searched, and when I turned off the heater, it started to work again.

Voilesetvoiliers.com: Is it true that your bag of food for the passage of Cape Horn bearing the n ° 52, you planned this year to cross it after 52 days?

ALC: I think it's time we had been there four years (the record is 52 days Gabart 6:18 minutes ed), and so we decided to stay on the same figures with Sébastien Duclos when the catering was done, because we had already been fast enough. There we are at how many days? 42? (45 in fact, note) I have not even counted (we give him the answer again when we talked a few minutes ago, ed.) Oh ok. Well, it's going to be around 47 days. It should be a little earlier than expected! We will not complain ... and so I have extra food to finish the Vendée. I can even feed my friends ... I do not know if I will have other worries, but not the lack of food contrary to eight years ago when I had arrived with nothing left to eat.

Voilesetvoiliers.com: All the observers are unanimous on your perfect trajectory. Looks like you've never mastered the weather so well and everything looks easy?

ALC: (laughs) No, it is not easy! (Laughs) They ask lots of questions. In terms of weather, I try to do my strategy without too much wondering what my opponents wil do, and I advance piece by piece. The weather models are almost always agreeing with each others, the routings are not always effective, but I always try to find a trajectory that seems to me the best. And then in the famous transition periods, when you have to stoke the boat up to pass these important phases, as a few days ago with this ridge under New Zealand, you sometimes have to be tricky. Same, when you have to push the boat to stay ahead of a front. Overall, I feel not too bad about it, even if I did some not so good stuff.

Voilesetvoiliers.com: How do you see the climb up the Atlantic where four years ago, François Gabart have slightly dropped you when you navigating virtually in sightof each other?

ALC: I know that the South Atlantic is a very very complicated part, weather wise. I suffered eight years ago and again four years ago. I'm starting to look at what is brewing for us. We will try not to do too many fuckups in this delicate part that lasts at least as far as Rio.

Voilesetvoiliers.com: Finally, you have time to follow a few news including the record of Thomas Coville?

ALC: Yes I follow what happens. They give me info. I had the times of Thomas. This is an amazing feat he is making! And we realize the speed of the boats, because he left the same day than we did (November 6) and he will arrive shortly after I crossed the Horn. This gives an idea of ​​the differences with our IMOCA ... which however are not slow!

I think you meant this....

Lous,

Chafe. If the block isn't designed for it, it's a no go.

Loop designs have issues as well, the biggest being chafe which is easily identified but still difficult to deal with when it fails.
I get that if rigged through the centre of the block it would chafe. My point was that a slack loop could have been employed as a fail safe. Doing so would have saved his rig and he would still be in the race.

Merry Christmas to all.

The Boss has the hammer down again this morning. Good to see.

Such a pity for Alex that HB is wounded. Still, it's a long, long climb back up the globe from down under.

Laurent, thanks man,

the heating crashing the AP, damn, and no chinese gybes... nice.
Contrast that to what Conrad wrote:

"It's Christmas season and I'm sure you are all rushing around and sometimes lose track of which way is up. Sadly my boat has the same problem as it keeps falling over! [...] . Since the first wipeout this way after the fire, this was the fourth episode like this so far in this race and while I'm sick of picking the boat up after it loses its mind I am starting to become quite adept at dealing with what is normally classified as an emergency situation! [...]"
