New Speed is Good Speed
An article from Captain Kent Dresser
When docking and maneuvering powerboats, momentum is often times your worst enemy. Outboard, Stern-drive, and Twin Screw vessels are most responsive to turning and maneuvering with propeller thrust when they are first put in gear. Developing a balance between using the thrust of the propeller to move the boat in the desired direction and gaining too much momentum will allow you to dock with more control and ease.
This is not the case with sailboats where momentum is almost always necessary when docking.
