Jibing a mainsail:
The only safe way to jibe in a breeze is to lower the peak and top up the boom, before getting the sail over. In ordinary airs you can jibe a boat if you pay attention to the helm, and get the sheet down flat. Let her come easy. If forced to jibe all standing with the sheet off, just as soon as the boom comes over put your helm, hard the other way, so as to throw the boat round, and get the wind back of the sail. This will break the force and save the knockdown, but is liable to break the boom. If fitted with backstays, look out for them.
