How to Raise a Mainsail Safely
- 1). Uncover the mainsail and store the cover below decks or in a lazerette.
- 2). Determine which halyard is used for the mainsail. Usually sailboats are rigged with the main halyard on the starboard side and the jib halyard to port.
- 3). Open the shackle and free the main halyard from wherever it is stored, usually on the life lines or at the end of the boom.
- 4). Walk the halyard to the mast.
- 5). Verify that your halyard is free to run clear of the spreaders and shrouds, not wrapped with another halyard.
- 6). Attach the halyard shackle securely to the head of your sail. Check to see that it is correctly fastened.
- 7
Loosen the main sheet. The main sheet is the line that controls the lateral movement of the main sail. - 8
Head the boat into the eye of the wind. This will keep the mainsail fluttering amidships and prevent any danger of being knocked overboard by a loose boom. - 9). Stand facing the mast with a wide stance to give you proper balance and leverage.
- 10
Hold the halyard with one hand above the other. - 11
Pull downward on the halyard using your arms--hand over hand--until the main sail is up. - 12
Repeat the downward pulls until your sail is all the way to the top of the mast. - 13
Use a winch to pull the main snugly into position so that there are no wrinkles along the mast. - 14
Furl the halyard and hang it from the cleat on the mast. Unfurled halyards have a tendency to fall overboard and wrap around propellers at inconvenient times. - 15
Walk back to the cockpit, turn the boat away from the eye of the wind and haul in on the main sheet until the sail fills with wind. - 16
Instruct the person on the helm that you are ready to sail.
