Dave's math is right. These guys may know their stuff on software but they don't apparently don't know much about racing a sailboat. To win you have to work ALL the details. Completely dismissing any of the components is professing ignorance.
The racing software helps.. to a point. I've used their stuff, it's nice for the start line. I use the built-in stuff on the Zeus, it helps with laylines and windshifts for example: can do an A <-> B on one tack vs another for VMG to a given waypoint . On VMG, both are useful, VMG to wind more so. Tacking on headers is also important but that has to be tempered with common sense and chasing puffs as well... Sometimes you sail from a good pressure zone to a calm area and you effectively outrun your wind on momentum which makes it look like you're getting headed... + Sail trim + rig setup, + fast bottom, + fast sails, + competent crew, + luck,+ good start, + , +, +, + Neat software helps, but ALL of it counts.. That's what makes it so much fun, the never ending quest for the perfect run. :-) Have fun racing, we're hoping for good wind on Wednesday! -Francois Rivard 1990 34+ "Take Five" Lake Lanier, GA
