Has anyone had a problem with there tiller pilot sudenly deciding to go hard to port for no reason.last night i was sailing to pancake creek running at 5 knots and it went to hard port.got boat back on course engaged tiller pilot same thing. Turned it off and back on same thing, decided to go back to bundaberg as we were only 3 hrs into the sail.did the same thing heading back. Will probably send it away now as i dont trust it was great all the way from sydney and its only 4 months old.
