Newbiesailor,

Sorry about that,

MOB is short for man-over-board

Weather helm is the tendancy for a sailboat to steer into the wind (head up) all by itself. ie, the boat wants to weathervane of its own accord. You can feel this yourself in the tiller-tug that occurs as the boat tries/wants to do this. As I have read and found myself, the more you rake the mast back, the greater the weather helm, and this weather helm is expressed at the tiller as tiller-tug. Which in-turn can be reduced by following the HobieCat instructions on how to rake the rudders forward. But, that is another post!
