How to Avoid a Gybe Broach

To start with, you can’t sail the boat the same way in heavy air as you do in more moderate conditions. You have to trim the sails tighter and sail as much as 10-20 degrees higher than dead downwind.
To reduce the chances of a wipe out, you need to prevent the boat from heeling to windward. When the boat heels to windward, the center of effort shifts to windward, forcing to boat to turn to leeward. At high speeds this can make the boat uncontrollable because an attempt to correct the course results in the rudder stalling. This video gives some tips to help prevent gybe broaches.

We had exactly the same outcome last Saturday - also on a F40, stbd downwind in 20+kts just like this. We didn't snap the pole, but we did destroy the kite. As the trimmer, I'm studying this video to look for the point of failure. The UK sailmaker commentary blames the helmsman, saying the crew work was fine. Other comments sheet it home to the trimmer. I'm coming to the view that in the video the boat was too finely balanced, with the helmsman struggling to keep the mast to leeward, and suspect that from the get-go, the kite was too full, and it was only a matter of time before it crashed. Not blaming the trimmer for easing the sheet at the critical moment, the problem existed from the start. I think it's wrong to blame the helmsman for lack of attention, but, given the skill level of the crew, correct to blame the skipper for allowing the boat to be sailed on such a knife-edge. What was the grinder doing, sitting astride the winch looking aft? And how about trim2 on the brace, scrambling away from the winch when he might have saved the day by easing the pole forward. In those conditions, if you're going to set the boat up to do 18+ kts you need more crew training. So do we, but we don't get many 20+ kt days to practice.

When "on the edge" like this... when you know there is a real risk of a round down... there are things the crew can do when the helm starts to lose control (and frankly before they lose control)... be prepared to sheet the spinnaker like crazy to drag as much sail area as you can to the leeward side as fast as you can... the grinder should be grinding as soon as the boat starts leaning to weather and not wait for the helm to declare they lost it, this often will "save you" (though you may then round up but better then rounding down)... someone on the vang ready to blow if if the main jibes to avoid a boom in the water, broken boom, and to make it much easier to jibe back (assuming you haven't broken anything)... someone on the foreguy and someone else on the topping lift ready to get the pole high enough to not be dragged in the water during the round down... and last bit of disaster planning is the spinny halyard nicely laid out ready to blow at a moments notice. Oh, and everyone on deck having several times talked thru what each of their "to dos" are whenever the boat rolls to weather (go thru the motions on every weather roll not just the "too big one" which the objective is to prevent.

Respect for the way this sailor is pushing his ship to the absolute max.. Chapeau!!

Bring a chair in summer to San Francisco's waterfront, and watch knock downs all day long. Even in boats sailed by pros.

For me, at 3:10..., the trimmer is loosing sheet in the puff. The Spinnaker gets round and starts twisting. You can see, he is loosing concentration, sheet is coming off, he is trying to trim in, spinnaker is forcing to windward.

After seeing that wing-wing configuration and the speed....I said “oh man”. LOL.

I would recommend a reef or two in the main. Massive control gain for giving up a puny amount of sail area. When I need a reef upwind, its just as useful going downwind.

My best ever video about spinnaker in strong condition. Serioustly!! ❤

Sailing dingies at the Cape lower the spinniker and tack then hoist again by the time the compition recover from their capsize ypu are miles a head

Thank you
-
Very very important to know
-
Going out the backdoor!
-
Good speed.

If you go to watch an F1 race live, you can see what you don't see on TV, that the cars are on the verge of crashing off the track for the whole race. This is the same. If you sail at ludicrous speeds, eventually you will crash. But if you don't, you lose.

Would it have been possible to tie the boom forward? I saw a different guy call it a boom stay. Is that not for all rigs?
-
That main was always in too much contact with the shroud and as the narrator says they should have been 10 degrees higher
-
Maybe some vang, look at the mainsail twist off at the top.
-
Why was there no preventer ?
-
would preventer help to avoid this condition in any way?

That skipper will have a back problem. Horrible posture. Should stand centreline.
