sailing in circles! please help
It sonds to me as though you have no boat speed after you have gone head to wind. To help keep your speed up fall off a little befor the tack and get as much speed before the tack as posable. Once you go past head to wind over sheet the main and leave the jib out just a little. Try to drive the boat with a small luff in the jib for a few boat lenghts and then bring it in tight. With out boat speed after the tack the boat will fall off no matter what the ruder position.
hope this helps.
