ORD-16c Able Elective Triangular Sail Instructors: George Crowl

Course Outline 14a. While leading a crew of not less that two other persons, demonstrate your ability to sail a sloop or other suitable vessel correctly and safely over a triangular course (leeward, windward, reaching marks), demonstrating beating, reaching, and running, and the proper commands.
3
Points of Sail (1)
4
Beam Reach Sail Force of wind (= 1.0) pushes on sail Force pushes forward (= 0.7) Force pushes sidewards (= 0.7), but is resisted by keel / centerboard 1.0 0.7

Tiller / Wheel 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” Wheel turns same way as a car It is less obvious how much rudder has turned Normally, small motions Tacking – 45° rudder angle, most efficient Jibing – less rudder angle, more gentle
7
Tacking 1. Starboard Tack 2. Passing through the eye of the wind 3. Port Tack Wind
8
Crew Coordination Scout must be in command Provide warning “Prepare to tack / jibe” Execute commands “Helm's alee” or “Jibe-ho” Crew tighten main to start both tacks and jibes Crew tighten downwind jib sheet as needed As vessel passes through “Eye of the Wind”, release downwind jib sheet, haul in opposite sheet Crew release main sheet slowly to new position Crew tighten jib sheet with crank Helm establishes desired heading
9
Beating to Windward Series of tacks Short tacks are more work, lose speed each turn Long tacks more efficient, take you away from area
10
Gybing /Jibeing Enough speed to turn Sail to centerline first Tiller to windward slowly, wheel to leeward slowly Shift weight if needed After sail shifts, move sail and tiller / wheel to take up heading desired
11
Triangular Course Typical One jibe, two tacks Upwind, downwind May need to beat upwind Scouts demonstrate ability to sail course with help on main and jib sheets in sloop Can be short legs
