I guess ymmv. I don't say to slow down (not that it matters that much in a keel boat; the chances are small that you will be going much faster than 6-8 kt, depending on your LOA), only to turn slowly.
I do the complete manoeuvre by first getting close to running, switch the jib to wing on wing, then sheet the main in and at last complete the jibe. So far (40-odd years), it worked for me. I never tried to jibe in anything higher than 30 kt., but it did work for me on various boats (24 - 50 ft., in- and off shore) with the wind in the upper 20s. Of course, it does not mean that i do it right. Quite possibly, i was so far lucky. Sailing on a dinghy, it works a bit different. The forces on the sail are smaller (e.g. you can grab the sheets and move the boom to the other side) and the boat stability is less (you can easily land in the drink, if you do a jibe the wrong way). Not to mention that you are probably planing before the jibe. Btw. I am not racing, so what i said may not be optimal, but i still believe it is safe. Marek David Knecht wrote: I have some concerns with what has been said. If it is blowing 10-15 and you are wing on wing by the lee, if you slowly pull the main into the center, you would have to head up to prevent premature gybe. This will kill the wing on wing as well as the main efficiency and both are going to slow the boat and increase the wind pressure on the main. That will make it that much harder to gybe and that much more force when the boom does come over. In dinghies, we do everything possible to have the boat going as fast as possible when we gybe and never pull the boom in much before gybing. So it seems to me the message should be coordination to keep speed up as much as possible and do it fairly quickly or everything will get harder. Gybing slowly sounds like a recipe for trouble.
