The sheet is the mainsheet, the one many boats have for bending the mast while sailing to correct the mainsail farther provisions.
The form of the sail alters, not its in-or-outside place. Occasionally it is better in the event the very top of the sail turns relative to the underside, to shed wind (or enable wind to escape in the sail) on a blustery day; do that by pulling the voyager in and alleviating the sheet to let the boom lift in tough puffs of wind. But on a calm day the sail must have small turn, which means raising correcting and sheet pressure in-or-out place together with the voyager.
And that is only the mainsail! We haven’t started on the jib nor place the spinnaker -sailing excitement. Who says sailing is not difficult? In the most effective method, although it is difficult. Even when you sail for 30, 20, 40 years or even more, you will constantly keep learning, constantly keep enhancing, and not get drilled. It is a sport to get life.
