Slip reversal: how to back up without becoming the marina's featured attraction

Article Abstract:

All motorboats have an asymmetrical thrust caused by the angle of the propeller blades. It is more pronounced when backing up because it is not offset by the prop wash. Reducing power and steering precisely are the best strategy when backing into a slip.
