Chinese Gybe

[AIDY]

Anyone know what a chinese gybe is ?

Whilst reading the logs from the challenge boat "Team save the children", there was a suggestion of a chinese gybe in a force 10 last night somewhere off portugal.

TIA

Usually an unplanned shroud to shroud gybe.
Don't know why its credited to the Chinese though.

Hi
I was taught many moons ago that a Chinese gybe is what you can get if you gybe without a kicking strap to hold the boom down. As the sail goes thro' the wind the sail can lift - or kick - the boom up. Never done it but always had a kicking strap.

refers to a situation where the top and bottom halves of the main are on different gybes with an almighty twist in the middle and the boom going skywards. fortunately rare these days as it can't happen when you have a kicker set up.

That is also exactly my understanding - but I have no idea what the source was. Possibly childhood Arthur Ransome reading.

Thanxs guys.

I have also just been told it could be this :-

A Chinese Gybe is when the wind gets on the wrong side of the boat and pushes against the main sail and the headsail/kite. The boat is pushed over on its side as the main sail is held in place by a preventer.

I agree.

Following options from the web:
(1) broaching (bow points too close to wind and boat heels over severely) or doing a chinese gybe (stern goes involuntary through the wind)
(2) The graphic award winning picture of the colourful Sunshine Coast skipper Bob 'Sir Robbo' Robertson's Farr 40 "Queensland Maid" executing a free standing pirouette off Sydney's North Head embraces all of the aciton which is experienced in a full blown "Chinese Gybe".

(3) Kicker, Cunningham and Outhaul should be tightened to flatten the sail to prevent a "Chinese gybe". Minimal twist and belly in the mainsail will help a great deal to get the boom over with the least drama
(4) A Chinese Gybe is when the wind gets on the wrong side of the boat and pushes against the main sail and the headsail/kite. The boat is pushed over on its side as the main sail is held in place by a preventer.


Lots of other reference on the web proving that as a term it is being used incorrectly probably more times than correctly. IIRC it is the wind in the top of the sail blowing the top one way, whereas the wind in the bottom of the sail is blowing the other, so you end up with a nice twist in the sail and the boom high in the air. Cant happen if the kicking strap is tight enough. I think it is termed a chinese gybe cause the junk rig is more susceptible to it.

Further research on the subject reveals that the correct cry to give warning of Chinese Gybe is:

" OH S*** WERE ALL GOING TO DIE"
And that if the event was survivable for the skipper to pass amongst the crew anointing their heads with a winch handle while uttering unintelligible oriental curses(Hence Chinese)
If the skipper was involved in the manoeuvre the procedure is for him to shrug his shoulders smile nonchalantly saying"well that shook the cobwebs away" before retiring below.

I agree with Snowleopard, it's when your boom gybes and your gaff doesn't. I don't know if it is posible with bermudan rig. An unexpected gybe is usually a gybe all standing.

Possibly when it reduces the rig to junk.

Maybe not completely possible with Bermudan rig, but a very good imitation is certainly possible if you have a long boom. A gybe without a tight kicker can result in the boom lifting so that it can't pass the back stay; the boom then stays on one side while most of the sail goes across to the other.

No, its when after having a satisfying gybe you feel ready for another one an hour later./forums/images/icons/laugh.gif

I also was under the impression it was a gybe where the kicker was loose, another danger on my boat is that if this happens .. and it won't! .. is that the boom rises and whacks the backstays.

Now my interpretation is that a Chinese gybe is the final act in a series of death rolls, to leeward and then to windward. The final roll can be where the boat heels so far to windward that the rudder sucks air, the boat broaches round to leeward and the boom then gybes. If the final roll is to leeward, you just get the ordinary comfy broach.

Stopping death rolls is a whole 'nother subject in itself.

edit. ps. that's what's going on in the picture up top.

spect the "chinese" part has similar origins to a chinese cut in cricket, also known as a harrow drive where the batsman steps stylishly onto the front foot to give it all he's got only to see the ball balloon backwards, often with enough force to clear the slips and score runs. In other words, a bit of a ballsup. No idea why chinese though.
