When there're two of us on the wire, on a beam reach, I find that I have to 'push away' the tiller to keep the boat on course and the tiller feels really heavy. In Greece last year I don't remember this being a problem at all. Is it poss that the rudders are set wrong (they look okay), or just that we're too heavy for the boat (combined about 160kg). Anyone got some advice for me? thanks.
