Windward sailing also does not work if a boat is pointed directly opposite the wind direction, according to The Physics of Sailing. Wind has to be moving against the boat at an angle of at least 40 degrees for most vessels. Angling too sharply into the wind causes the forces on the boat to become unbalanced, and moves the boat sideways in the water. A sailor intending to travel windward toward a point exactly in line with the direction of the wind will have to zig zag back and forth to reach its target. Using this "tacking" technique, and traveling at an angle as close to the wind's direction as possible, sailors can reach a point in any direction, regardless of the direction of wind. ---> sage
Will today be a rare Inside Day or will we take out either 4018 above or 3957 below by the Close? Place your bets.
85/87 is a potential reversal area and we're working that one now for at least a pullback, but I'm thinking higher from here.
