Vocabulary

Adujar, coil. Lascar, ease. Hacer firme, make fast. Abarloarse, raft up against another boat.

Leeway comes from wind. Drift comes from current. Steerage way is the lowest speed at which the rudder steers.

Activities

• Marina docking simulatorPractice docking and unberthing maneuvers with wind, prop walk, bow thruster, fenders and mooring lines.
• Propeller and rudderRight or left-handed, ahead or astern: which way does the bow swing?
• Decisions on boardFire, leaks, person overboard and more.
• Knots and linesWhich knot to use, and the name of each action.
