When I purchased my 424 the sea trail showed that the helm was light to the touch when under power. I did not move the vessel for a couple of weeks and then took her out to get her refueld. As soon as I was under way under power the helm had a strong pull to starboard. I am struggling to understand what might have happened. Is this an imbalance issue (e.g. too much weight on one side of the boat?
My boat pulls hard to starboard under power also. This is normal and caused by the prop rotation. Pearson offset the prop skeg a bit to compensate for this but under high throttle settings the engine will overcome the offset. Under moderate power settings, perhaps 6.3 kts or so, the boat is neutral. If I push the throttle up to over 7kts, it begins to pull hard to starboard. At 7.8kts, it will overcome the autopilot.
