PJ,
Not sure if others are actually answering your question: "how to reef?" versus "when to reef?". If not the latter, this is what we do:
Considering 2 people: captain (at the helm) and mate (wake her up). If we are into the wind, we trim the main first. If we are off the wind and need to reef, we trim the head sail first.
Upwind, start the procedure with the sails trimmed to tight upwind and the main at center or slightly on the port side. Trim the main. This is, by the way, the same procedure as furling in the main. Furling winch set to free-spin on the mast.
1) Mate: pass the outhaul to the captain.
2) Captain: attach the outhaul sheet to the starboard, aft (mainsheet) winch (at the helm) with 2 winds. This is used for back-pressure on the sail so it doesn't flap all over.
3) Mate: Attach the furl-in sheet to the cabin top winch, four wraps and wrap the furl-out once (or twice in heavy wind).
4) Captain: Steer into the wind, but a few degrees off dead upwind so the sail is on the port side.
5) Mate: Unlock the sheets: outhaul, furl-in, furl-out
6) Mate: Grind the winch while holding the furl-out. We have it wrapped once on the same winch.
7) Captain: Pay out the outhaul until the main is reefed.
8) Mate: Lock all sheets and trim outhaul as needed.
Note: We rarely reef the head sail when heading into the wind. If needed, we continue to reef the main. We also have electric winches, so the procedure above is slightly different with the Captain engaging all winches from the helm, even the cabin top.
Off the wind, if we need to reef, we reef the head sail first.
1) Mate: remove the 5th wrap (self tailed end) from the which, leaving four wraps on the winch (holding it with your hand) and wait to pay out the line, to assist with sail control.
2) Captain: attach the furl-in line to the main sheet winch, 4 wraps, leaving the sheet locked.
3) Captain: steer further down-wind.
4) Mate: let off the jib sheet depowering the jib fully, but maintaining control.
5) Captain: furl in the jib with the furling line, to the desired reef location (ensure the jib sheet is locked).
6) Mate: reattach the jim sheet with four wraps, trim the jib
I would like comments on "how" others reef with a furling main/head sail and single line reefing system. We do also reef the jib into the wind, but we don't like all the flapping around. We also furl-in the jib fully when down-wind with all the pressure off the headstay.
I'd love to hear other's tips on reefing in heavy winds; do you follow these procedures or what do you do differently??
PJ, hope this makes sense and helps!
