  • Reefing allows you to reduce the sail area of your boat. This will allow you to keep

  • in control on windy days. It’s best to reef ashore, and if in doubt put a reef in. You

  • will have a number of reefing points that allow increasing amounts of reefing to be

  • applied to the sail. In this example were starting with the mainsail fully rigged and

  • hoisted.

  • First release the reefing line from the boom and pull all the slack through. Thread the

  • end of this line through the first reefing point behind the mast, and on the other side

  • of the sail return the line to the boom but keeping inside the kicking strap. Tie the

  • end of this line to the boom with a bowline.

  • Next go to the end of the boom and pull the remainder of the reefing line out like this.

  • Return to the mast and release the main halyard to lower the mainsail, then return to the

  • end of the boom and thread the reefing line through the eyelet of the clew of the sail

  • like this. And return the line to the boom and clip it in place.

  • Return to the mast and pull the reefing line tight. This pulls the clew down to the boom,

  • and tensions the front of the sail. You may need to adjust the halyard slightly to ensure

  • that the reefing point ends up tight to the boom. Tidy up the slack on the reefing line

  • to stop it getting tangled. And finally, tie the sail to the boom using a reef knot. Repeating

  • as necessary.

  • Repeat the process to subsequent reefing points if it is particularly windy.

  • You can reef the sail when the boat is tied to a pontoon, and you should familiarize yourself

  • with the whole process so that you can reef afloat should the need arise.

  • Let’s look at another example.

  • The reefing line is released from the boom, and threaded through the first reefing point

  • in the sail behind the mast. And then led back to the boom and tied with a bowline.

  • The main halyard is then released to lower the sail, the outhaul end of the reefing line

  • is then threaded through the clew of the sail and led back to the end of the boom and clipped

  • in place. The reefing line is then pulled tight to tension the sail, with the main halyard

  • being adjusted so the first reefing point ends up by the boom.

  • Continue to pull the reefing line to make sure there is no slack.

  • For single handed boats that don’t have wire rigging to support the mast, reefing

  • is simple. Disconnect the outhaul from the clew end of the sail, and simply wrap the

  • sail completely around the mast. You can do this several times if necessary. Finally reconnect

  • the outhaul back to the boom.

  • Whichever reefing procedure youve used, to take the reef out you should reverse the

  • process. To lower the sails release the halyards and gently pull down. To pack the sails away,

  • it’s best to roll them from the head of the sail. For the mainsail two people make

  • this easier. For the jib, roll the sail up using the wire. Starting at the head, continue

  • winding around until you reach the end. Then finally slide the sails into the sail bag

  • to store them away. If you take all the battens out of the sail after use, you can fold the

  • sail like this. With a friend, fold the sail working towards the head. And then finally

  • roll the folded sail up.

  • Being completely familiar with the rigging and reefing process is an important part of

  • sailing. In time you will get quicker at the whole process.

Reefing allows you to reduce the sail area of your boat. This will allow you to keep
