  1. SAIL TRAINING HAMPTON ROADS NROTC

  2. Learning Objectives • The student will: • Have knowledge of different types of knots • Be able to identify different boat types • Identify parts of a sailboat • Have a basic understanding of how a sailboat operates • Have a better understanding of how wind and weather affect sailing

  3. Knots • Figure Eight • Bowline • Square Knot • Clove Hitch • Half Hitch • Sheet Bend • Proper way to secure a line to a cleat

  4. Boat Types

  5. Rig: the configuration type of the mast and sails Cat-rigged: single or two-masted boat with NO jib (LASER) Gaff-rigged: sail is square with top edge supported by a spar called a gaff Double-headsail-rigged: two jib sails flown at same time, as found on cutters

  6. Laser sports an efficient “cat” rig with standard control lines (cunningham, outhaul, and vang) low-drag, high lift foil section for the daggerboard and rudder fast, responsive, LESS forgiving than other training boats LOA: 14’ Displacement: 130 pounds

  7. Dinghy: a small, light sailboat or rowboat • Small boat: a daysailor that is less than 30 feet long

  8. Daysailor: a boat without a cabin that is used for short sails or racing

  9. Catamaran: a multihull with two hulls separated by a deck or crossbeams from which a trampoline is suspended

  10. Cutter: a single-masted boat that flies two jibs at a time

  11. Sloop: a single-masted boat that flies one jib at a time

  12. Ketch: a two-masted boat whose after mast, the mizzenmast, is shorter than the forward mast, the mainmast, and is located forward of the rudder post

  13. Yawl: a two-masted boat whose after mast, the mizzenmast, is shorter than the forward mast, the mainmast, and is located after the rudder post

  14. Schooner: boat with two or more masts, the forwardmost of which, the foremast, is shorter than the aftermast, the mainmast

  15. Parts of the Boat

  16. Gooseneck

  17. STANDING RIGGING Wire construction, holds mast in place under strain b. Adjustable with turnbuckles c. Permanently installed as long as boat in commission d. Shrouds support athwartships; stays support fore and aft

  18. RUNNING RIGGING Usually fiber line, or wire rope with fiber tail for halyard. b. Adjustable, and can be unrigged between sailing periods c. Used to control sails d. Halyards hoist e. Sheets trim or ease (change angle of attack)) f. Vangs and preventers restrain

  19. CLEATS Regular, horned type

  20. Theory of Sailing / Sailing Basics

  21. STABILITY Ballast: In centerboard dingy, provided by persons in boat In Keel Boats, built into boat during construction Hike out to counter wind gusts

  22. THEORY OF SAILING BOAT BALANCE Center of Buoyancy (CB) The point on the boat through which all Buoyant forces act

  23. THEORY OF SAILING BOAT BALANCE Center of Gravity (CG) The point on the boat through which all Gravitational forces act

  24. THEORY OF SAILING BOAT BALANCE Center of Effort (CE) The point on the boat through which all Aerodynamic forces act Center of Lateral Resistance (CLR) The point on the boat through which all Hydrodynamic forces act

  25. THEORY OF SAILING

  26. THEORY OF SAILING

  27. Capsizing • Causes • Recovery From Capsizing

  28. Approaches to a Dock

  29. Wind / Weather • True vs. Apparent Wind • Natural Wind Indicators • Onshore vs. Offshore Winds • Tides

  30. Rules of the Road for Sailing Vessels

  31. Rule 2 (a) The Rule of Good Seamanship • Nothing in these Rules shall exonerate any vessel, or the owner, master or crew thereof, from the consequences of any neglect to comply with these Rules or of the neglect of any precaution which may be required by the ordinary practice of seamen, or by the special circumstances of the case. • This part can be paraphrased as “There ain’t no excuse.” Remember you can be relieved of your command in the event of a collision.
