  2. Course Outline • 16c. Sailing: In a cat-rigged or similar small vessel, demonstrate your ability to sail single-handedly a triangular course (leeward, windward, and reaching marks). Demonstrate beating, reaching, and running. A qualified sailing instructor should observe this requirement.

  6. Tiller Operation • Push tiller the opposite of the way you want the rudder to go • “If it doesn't go the way you want, go the other way” • Normally, small motions • Tacking – 45° rudder angle, most efficient • Jibing – less rudder angle, more gentle

  7. Tacking 1. Starboard Tack Wind 3. Port Tack 2. Passing through the eye of the wind

  8. Beating to Windward • Series of tacks • Short tacks are more work, lose speed each turn • Long tacks more efficient, take you away from area

  9. Gybing /Jibeing • Enough speed to turn • Sail to centerline first • Tiller to windward slowly • Shift weight if needed • After sail shifts, move sail and tiller to take upheading desired
