A larger twin-screw motor yacht can present some docking challenges when the wind is blowing you sideways. Smaller single screw boats have the same problem too.
The primary needs Marc's clients have are docking the boat short-handed, handling the boat in close quarters, and anchoring/mooring at Catalina. Some are new boat owners, and others are looking for a tune-up on their anchoring and boat handling skills.
Spend a few hours, or spend a few days working with Marc on the skills you want to improve. Rates are $60 per hour, $400 per day. Please tell us what you would like to accomplish.
