Downwind Sailing
I think what you are asking is how to sail directly downwind, if I understand you question.When sailing downwind with any headsail other than a true spinaker will have the same problem of the main covering the headsail. The 3 solutions to this problem are:1. Head up so that you are not sailing directly down wind, to move the main so that it is no longer covering the headsail, which is what you ended up doing. This may actually be more effective. While increasing the distance to your destination, it will often result in an increase in speed that will more than compensate. 2. Drop the main so that it does not cover the headsail. This is effective if the headsail has more area than the main. It may also result in a shift of the center of pressure, which may make the boat easier to handle.3. Sail wing-on-wing, with the main and headsails on opposite sides of the boat. This can be tricky (a pole can help), and also increases the risk of an accidental jibe (placing a preventor on the boom is usually a good idea when sailing downwind).Also, you might try raising the centerboard, which does little when sailing downwind. The primary job of the centerboard is to keep you from slipping to leeward, but since you want to go to leeward (downwind), why let the centerboard slow you down.
