In Portugal in general and the Azores in particular, you breathe calm, goodness, well-being. Everything that should be: humanity. Mark, your music accompanies it perfectly.
More and more I am seeing metal break from normal use. Metal fatigue happens when cheap metal is used. They try and save money by using what they think barely covers the load and this is why you always oversize your rigging components and cables.
I recommend carrying several tension belts with ratchets as emergency spares(Spanngurte in German). There´s always an issue with space and weight on board, but these things can really save your day.
Very well done. Outremer owes you a very big thank you. Dyneema is great on short lengt. It has no stretch but it does have something called creep. Meaning it stretches about 2 % without coming back when the load is released. When it is fully stretched it becomes round and hard cause the stretch is in the weaving not in the fibers itself. So use it wisely 👍👍
You are not correct in all your points. Creep is permanent elongation of the Dyneema fibre when permanently tensioned at high proportions of breaking strength (higher than 20% of breaking strength). When Dyneema is used for rigging it is sized to avoid creep - static tension less than 20% of breaking strength will mean no creep will take place. And creep is a property of the fibres, not the weave. The weave does not stretch except when you disturb it by splicing - in that case any stretch that takes place as the fibres realign themselves after splicing is called constructional stretch. This should be allowed for when making a Dyneema stay.
Was this the furler that was on the boat when the front beam was hit? I can't remember if you changed it or not. I do hope they take the part off and get it tested though, would be interested to know how the failure happened. I'm not sure it would be bad metal, I wonder if it isn't some other kind of fatigue related failure. Good to know though all are safe, although not well.. damn covid... Cheers for the vid
Part of the “A-frame” was gone and the rest seemed to have detached from the rest of the cross beam. They did a really good job limiting the damage. You have to ask them though for the details as we can only guess
I thought you mentioned a new home being built. Will you build that in the Netherlands or did you find someplace or some island along the way in your travels? I thought I’d add that we been watching since the very beginning. What is that 5 years? So, while it’s the end of this chapter in your sailing lives this is more like the end of the book for us. We are anxious to see the next adventure.
Unfortunately it’s more likely that it’s a general problem as this is a very generic part of a generic brand used on all kind of boats. Someone suggested that it could be related to deteriorating quality of metal products in general because of recycling. We saw a strange spot on both sides of the fault and will send it back for inspection to the supplier. Both for Outremer and the supplier it was the first time they saw this
@@CatGreatcircle The 'strange spot' is most likely the load being over the capability of the part and if inspected before failure, would have been the first evidence of it about to fail. It is most likely indicative of stretching (and therefore localised thinning) of the part. Once this starts, total failure, of course, will occur very soon after. Before leaving port all rigging should be inspected, especially turnbuckles, swages and adapters! You MAY have seen this earlier and been further from catastrophe than you were.
@w4vp9kf thanks for your feedback. Looking at the circumstances we were not even close to loads that could have caused this if the part had been according to the design specs. But let’s wait and see as the supplier has already announced it will investigate the piece thoroughly, it’s already on its way to be examined. Suggesting that the naval architects of VPLP would not be able to take different loads on a cat compared to a monohull might be an indication of your personal preference. We like (some) monohulls very much too and there is still one waiting for us in front of our house… For the journey we made in the last 9 years there is not a single doubt in our minds what is the best choice for us. Half of our around the world fleet were monohulls…those crews are heroes.
Stainless steel 316 or class a4 .. not being treated properly. Bigger production, Cheaper stuff , Ess furrow design & spec. quality gone. It’s ok if oversized but that’s not case. Bad rigger, bad supplier bad design.
You don't have to know much physics to realise that the load on a catamaran's rigging is enormous! On a monohull, the boat heels and takes the strain off the rig by spilling wind (most failures on monos are backstays because the boat is not 'giving' when going downwind). On a cat it doesn't. All of the 'power' of the wind is bourne by the rig. You should design for 4x the loading. The huge sails on modern day cats make this imperative. I'm 99% sure the other failed cat in this video was completely under-designed and they certainly didn't hit anything. If they had hit a container, the whole boat would have suffered considerable hull and structure damage. Finally, don't use Dyneema for anything essential, especially not lower shrouds or lifelines! Only treat it as temporary, as was done here on the furler adapter. To see lifelines on HH (and others?) using Dyneema scares me to death. It'll be weakened by half within a year when out in mid-latitude UV rays! You should look at no more than a 3 year typical lifespan.
We just repaired the broken piece and will double check the top of the rig thoroughly tomorrow. You’re right this does make sense, but we did see a strange spot on the fault line of the broken piece, an irregularity in the metal.

The atmosphere on Faial and in Horta is just very special, even when compared to the very best locations we visited during our world tours
@@CatGreatcircle thanks for answer. It is received the same way. You are excellent at transmitting what you see in every place you pass through.

Spannend, goed gedaan en mazzel 😊

You are almost home - what's next? I hope you stay active - otherwise I'll greatly miss you. Jack - Houston, Texas.
Thanks Jack, yes sure we’ll be actively sailing for as long as we can. Hope to decide on the new boat in the next couple of months.
@@CatGreatcircle Well hot dog!! That's great. I look forward to following the next chapter. 😊

No before we had the carbon cross with a soft loop connecting the forestay. This part was new in Aruba
@@CatGreatcirclethanks for that response. I was wondering too if was furler hit by rogue boat captain
What was blurred?
The owner of a boat in the movie requested removal
@@CatGreatcircle That's okay, thank you for the reply
😀😀👍👍❤❤
Did that kinetic lost his entire crossbeam? 😮
Part of the “A-frame” was gone and the rest seemed to have detached from the rest of the cross beam. They did a really good job limiting the damage. You have to ask them though for the details as we can only guess
Mark, how far out do you think you are in ending the cruise? You’re getting close.
Probably our cruise will end at the Cannes Boat show this year in September
@@CatGreatcircle sad day for sailing yt =(
@@CatGreatcirclethen what??
We hope to know by then but this is definitely not a final ending

The Boat is for sale ?
Yes the new owner has it already listed to sell it again
So schön, wenn ihr deutsch sprecht :)
😎wir haben soviel französisch sprechen müssen dass wir gerne mal deutsch reden 😎
The question is: Is this acceptable on a catamaran of this price? Imagine the cost of loosing your mast and for what.....to save a few bucks!
