Mooring and anchoring

Two questions on knots, lines and anchoring.

Knots and anchoring

Bowline, fixed eye. Reef knot, joining two equal lines. Clove hitch, line to bar.

Garrear is dragging the anchor. Check shore marks. Mooring by the bight leaves both ends on board.

Activities

• Knots and linesWhich knot to use, and the name of each action.
• Marina docking simulatorPractice docking and unberthing maneuvers with wind, prop walk, bow thruster, fenders and mooring lines.
