Some of the sails would becalm the others, so the officer on watch would keep a careful eye on the wind and the trim of the sails to maximise the speed of the ship. "Carry on" was the order to lash everything up when the wind was just right. I'm not certain, but I think that this would usually occur when the wind was approaching from little behind the middle of the ship (abaft the beam, for you nautical types), though different ships handled significantly differently, and the way the load was stored and the degree to which the bottom of the hull was fouled also changed things a lot.
