Concerns
Chuck,I have to be honest with you. My old brain works slower than yours, and I could never explain it as well as Dave K just did. I just set my traveler up so that the car is in the middle when the winds are about 10 to 15 while beating into the wind. As the winds increase to say, 18 to 20 or more, I set the stops a little wider apart. This gets my boom out a little more, but it also enables me to keep my Leech at the same tension, while at the same time preventing my boat from heeling over excessively. If I just kept the car in the middle and let the sail out to prevent excessive heeling, the downward tension on the boom is lost. You need this downward tension to keep your sail tight, or else the sail bellies out, wind spills out, and speed is lost. It's all in the angle of the dangle. Now when the winds are ultra light, I want that belly in my sail. I want to let off a little on clew outhaul and the tack downhaul because I want to catch that light breath of air to make her sail. My 222 doesn't have a tack downhaul, so I'll let the Main Halyard off a little. I may take up on my topping lift a little. That's that do-Hickey that holds my boom up when I let my sail down, and prevents me from getting conked on the head. If I'm beating to windward on a long Port tack (the wind on the Port side of the Mainsail) for example, I'll set my car on the Port side. This looks kind of strange when you look at from where you are sitting at the tiller. The boom is on one side of the boat, and the mainsheet on the car is on the other side but in essence, the Mainsheet isn't acting as a sail tensioner. It's more of a boom/sail positioner. If you don't have a topping lift to take the weight of the boom, then the car in this position will keep that sail nice and baggy. This is the best way that I can explain it because I'm not too technically minded, and since my wife quit sailing with me years ago, I get all my orders from Penelope when I'm on my boat.
