I own a newport 27TM and am having severe problems holding on to this boat while sailing. I can go downwind ok but going to weather my boat has crazy weather helm. I have a wheel and I can trun it all the way to starboard and it wants to take off to port and likewise on the other side depending on the tack. I have a friend who is also a seasoned sailor and he said he thinks my rudder could possibly be too small. Has any one else had this problem? I race this boat and am about to sell it because it becomes very dangerous in heavy air. Thanks.
