Flying a Spinnaker
Barrie; You have 2 options: 1. find an experienced person to show you how to do it, or 2. Try it yourself in light winds.You definitely DONT want to try it for the first time in strong winds. In fact it takes a reasonable amount of practice to fly a spinnaker in strong winds at all. Plan on a minimum of three people and they all should be into it - none of those helping to fly it can be spectators and it really helps if they all understand how it works. I speak from experience - many broaches with spinnakers.Roughly, the drill is like this: (assuming that the sail is in a bag, without a douser)1. Get all the rigging ready (halyard attached to the head of the sail, sheets (guys) attached to the other 2 corners, pole set on the windward side of the boat, pole uphaul and downhaul attached to the pole, windward sheet (guy) led through the end of the pole.2. Adjust the pole to a level position using the uphaul and downhaul.3. Haul her up, watching closely to see that she unravels without a twist (called hourglassing). the guys will have to pulled in at this time as well, especially the windward one. The haul up is probably best done with the spinnaker turtle at the bow, although we have launched the spinnaker from inside the cabin on occasion, running the sail up the back side of the main so that it will not take on any wind until the head of the sail is at full height.4. After the sail is full, adjust the sheets. Don't worry, you will know when it's full. If you have your main adjusted correctly to the wind, the spinnaker pole will usually be in line with the boom when set correctly. This angle is adjusted by pulling in (or letting out)the windward sheet (called a guy on a spinnaker). You must also adjust the uphaul and/or downhaul when you re-position the pole because they may prevent it from moving if they are too tight. after there is wind in the sail, the downhaul will be most important since it prevents the pole from riding up5. Most adjustment after the sail is full and the pole is set in the right position will be done with the leeward guy as long as you don't change the boat's angle to the apparent wind. The lower windward corner of the sail should be right at the pole, and the head should be all the way up, touching the mast. The other corner will be flying free. Sheet the leeward guy in until you are sure that the sail is full - no flogging, no backwinding, then let it out until you see a small curl on the luff of the sail, and play the leeward guy in and out continually looking for that curl yet not letting it turn into a backwinded sail.When you adjust the course of the boat, you must also adjust the pole angle and the sheets.When it's time to get it down, be sure to let the pole off and steer the boat so that the main blankets the sail. You do this by letting go of the windward guy, but not so far that the sail can't be reached from the deck. If it's too far away, sheet in the leeward guy with the windward one still off so that it doesn't fill with wind again. You will need someone up there hauling it in or else it will end up in the water. Packing the sail into the bag correctly is critical, just like a parachute, to avoid hourglassing when hoisting. Separate the 3 corners and stuff the bulk of the sail in first with the center back of the sail in the bottom of the bag. Leave the 3 corners on the top so that you can hook them on next time. Getting the three corners mixed up at the top of the bag makes for some really interesting hoists.Mark the three corners well so that you know which goes where (they are usually color coded, so that helps a lot).Gybing means that mainly that the pole must be moved to the new windward side of the boat and therefore detached and re-attached from the appropriate guy. This can be difficult although it need not be if all on the team are watching and working together. The trick is to steer the boat and adjust the lines so that the person on the bow can reach everything at the right time. What can happens is that the pole gets detached and the wind takes both sheets away from the boat. This becomes difficult. On most boats the end of the pole at the mast gets moved to the new windward sheet and the other end goes onto the mast. The helper in the cockpit who is controlling the guys must ease pressure on these lines adequately to allow the pole to be moved. In big winds, these forces are great and it can get tough to do. using the main as a blanket can help. On the boats I have sailed, the pole comes off the mast first, then gets attached to the new guy so that at some point both ends are attached to the guys (for as short a time as possible) Then the end gets detached from the old guy and put onto the mast. Adjust all the lines, and away you go an the new tack. Oh yeah, of course you had to also gybe the main in there somewhere as well. This happens at the same time as when the pole comes across to the new position. There you go - hope it helps. It will all be a lot easier if you can find someone who has done this before to go with you a few times.ROwen
