We anchored at nearby Trappe Creek for a night to practice raising and lowering our mainsail in light wind. Steve, whose group installed the system, suggested we practice at least ten times. He suggested that one of us operate the winch while the other stands at the mast and watches to make sure the sail is even and not shifting backward or forward. George took the first shift at the winch. His ten practice sessions went very well. When it was my turn at the winch I did not do as well. Raising the sail is very easy. The difficulty comes when furling the sail into the boom. To furl the sail I wrap the furling line around the winch, then hook the halyard around a cleat and hold the halyard tight before opening the clutch. If I did not hold the halyard tight the weight of the sail would have caused it to fall to the deck. Also, if the luff of the sail (forward edge) is too loose the sail tends to shift forward while furling. If it shifts too far forward it hits the hardware and gets chewe
