Re: O'Day 25 difficult to turn?
This sounds very strange. The Oday 25 is a very manuverable boat. What you describe sounds like a boat going into "irons". That is, you are trying to swing the bow of the boat through the wind from one tack to another, and the boat stalls before it can get through the manuver, with the wind taking hold of the headsail and pushing the boat back onto the original tack. This can happen on any boat when you do not have sufficient momentum to keep moving forward (thereby keeping the flow across the rudder and giving steerage) because the boat wasn't moving fast enough when the manuver was started. With light winds, getting into irons becomes more likely. Next time, before putting the helm down and beginning the tack, fall off the wind a bit to build up some speed. Then put the helm alee. Keep the jib sheeted for the original tack and let the jib become back winded (i.e., let the wind catch the "wrong" side of the jib); this will really help swing the bow of the boat through the wind. As soon as the boat passes through the eye of the wind, release the jib sheet and haul in the opposite sheet and trim on the new tack.
