Dock Your Trawler Perfectly Every Time

Maneuvering a Single-Screw Trawler: Art or Science?

Backing a full keel, single-screw trawler has often been described as more art than science.  Prop walk creates significant docking challenges that are unique to trawler-style boats.  Numerous techniques such as the “back and fill”, and the art of “goosing” have been developed to compensate for the boat’s tendency to drift sideways when backing up.  These are good skills to develop, but are often ineffective in more challenging docking situations.
