Tavis, this is not uncommon. It varies from boat
. Typically as your sternway increases, some steerage control is regained. Often, once you get sternway, you can put the engine
in neutral to gain a degree of steerage. Slowly add power in short bursts to increase sternway. Alternatively, you must give brief bursts of forward power with your rudder
hard over to whichever side you need. The trick is to not use forward power so long or strong that you kill all headway. It's practice thing.
Some boats are real buggers and others not so much.
