Stopping the yacht is great advice, but if you haul the tiller to windward that will put the boat into a crash gybe, downwind of the MOB - the accepted technique was to tack and then leave the boat lying ahull. This "crash stop" technique was created by US Sailing's safety committee after some pretty good research. I met the head of the committee, a former US naval officer, many years ago in Newport RI and the technique they evolved didn't include lashing the helm. But their technique did stress, as you say, stopping the boat ASAP.
If you are close hauled it will not be a "crash gybe". The first time it was done on my boat, it was by John Armstrong from the Gold Coast Marine Academy.
There were 8 of us on board who were all Master Vs and operating sailing charter vessels out of Cairns. We flew John up for the weekend for him to examine us all for our AYF Offshore Yachtmaster Certificates.
John was steering and he asked me "What if I just hauled the tiller to windward and held it there?"
I said "What???.....and gybed the boat?"
He said "Yes."
I said "Well, I'll wrap that winch handle around your head."
He laughed and said "Look, we are close hauled and the traveller is cleated off, so it is just the sail that will flick through the gybe. Because we know how these yachts behave, we know we won't break anything. Let's just give it a go?"
Grudgingly I said "OK."
Now the yacht was an alloy Peterson 42 IOR 2 tonner in cruising trim and displaced 12 tonnes. We had the right amount of sail up for the conditions and we are going along at about six and a half knots and it was my boat, so you could understand I was a tad anxious.
So at his bidding, we did not touch the sheets or anything else, he heaved the tiller over and held it there and we were all gob smacked and amazed.
The boat came around, the main just flicked through the gybe, the head sail backwinded and lay over the shrouds, the boat stopped dead in it's track, stood upright and gently and slowly crept to windward.
You can just lash the helm and the boat will look after itself and you can go and do whatever you have to do, such as make a cup of coffee or lunch, attend to an injury or even rescue a man overboard.
When you are ready to go again, release the helm, steer through the gybe again and get back on course.
Heaving to is an invaluable manoeuvre and everybody should practise it on their yacht to learn how it behaves when hove to. Give it a try next time you are out sailing. You won't break anything except your misconceptions.
