yes, per jameslittlewood (what a terrible name to be given) below, the Cunningham may not have been eased quickly enough on the bearaway so the wire/rope in the luff pops and CRACK. I would like to the hear the onboard audio of that.
Fortunately no-one injured, which could easily happen. I’ve experienced a dismasting in a 40 ft. Malcom Tenant Wild Thing trimaran more than a decade ago. Not a pleasant experience although we were happily uninjured too.
Mast didn't fail.. it only takes a pin in the headstay to fatigue.. it'san made it'll fail somewhere.. but.. wind was at the top of the range.. someone puts a little too much clew tension on the "hydraulics".. shot loads.. carbon sails & no stretch.. it's all an experiment.. so many variables in engineering these
They just cut away the failure part off the video, but looks like mast fails under compression, as the first thing we see is mega sag in the headstay, whilst still attached om noth sides😅
Those things would crumple if you sneezed near them….. Here’s a suggestion for the future - the Americas Cup should consist of four laps around the Isle of Wight (in winter…..)
Its not mast built problem! Its how build load and thinking about what all bend on it! Every team knows structural strenght and if design sails and zwist wrong thats happening? Sail controll,headsail controll and point of fixed all its AC perfection of getting most of having... Maybe alinghi must rethinking mutch not only a new mast and its fixed!
Upwind cunningham tension probably wasn’t released with mainsheet ease on bear away, pulling luff rope out of track below the spreader. No backstays or intermediate runners, the main effectively holds the mast up. Twang time.
@@jameslittlewood7821 Dang sounds like you know quite a bit about a double skin mainsail and how it’s trimmed. Is the Cunningham connected to both mainsails?
@@jameslittlewood7821 Dead right I reckon. Big bear-away at top mark, big ease of main sheet tension without easing cuno, entire rig load goes on to luff of sail and tears track off (you can see the main separating from the mast). Without the main taking the load, the only thing keeping the mast in column was the structure of the mast, so it snapped like a toothpick.
ETNZ 7th April Auckland from 6:40, winds 25-35....but where they are called "back paddock"you can always add another 10 onto official number of the day due to the topograhpy of Auckland.I bet the swiss have their slide rules out at this time...th-cam.com/video/HPmKugCkHXQ/w-d-xo.html
Interesting that the luff seemed to pull away from the mast potentially triggering the break.

Kiwis were hammering it in close to 30 knots in Auckland. No doubt a “lets see if it breaks” test. I don’t think they’ll be too concerned.
More like 40 knots.

Better now than later. All the best from NZ 💪🏾🙏🏾

It looked like the forestay went first then mainsheet tension did the rest.
ETNZ sailed in 30 knots if i recall and probably were going better to break shit here than over there

Do you know how much pressure is on that rig?
Its not mast built problem!

Tragic
Mast step shear, Wow! ❤
“Dismasting” sounds like quite a euphemism for catastrophic failure, but I’m certainly no sailor!
Looked like either mast step or headstay gave way?
Both are terminal

Unluggy ⛳
this is probably a manufacturing defect.
Swiss sailing...
J'espère pas de blessé
red bull bought the mast from ali express this time they will buy it from temu. 🤣🤣🤣😂😂😂😂🤣🤣😂
go back to wood masts
