SKILLS

Preliminaries

30. Locate and examine for compliance the vessel’s federally required and ASA recommended safety equipment.

31. Demonstrate on shore or aboard the vessel the correct method for putting on a life jacket while in the water.

32. Identify the vessel’s battery selector switch and power distribution panel and ensure all switches are in the proper position for getting underway.

33. Ensure navigation lights (sidelights, stern light, steaming light, and anchor light) operate properly.

34. Perform a radio check using a working channel on the VHF radio.


Navigation

35. Visually pilot the practice vessel in and out of a harbor, correlating nautical chart symbols to actual landmarks and aids to navigation.

36. Steer a compass course (+/- 5 degrees) under power for a minimum of five minutes.


Under Power

37. Visually inspect the auxiliary engine and demonstrate safe engine starting, operating, and stopping procedures. Demonstrate proper gearshift and throttle usage.

38. Ensure vessel & crew readiness and depart dock or slip smoothly and under control.

39. Approach a mooring buoy (or other mark as a simulation if no mooring available); stop the vessel within boathook reach; attach the vessel to the mooring using an appropriate line or bridle; cast off from the mooring and get underway.

40. Set a bow anchor in water depth 8 feet or greater, using correct procedures including hand signal communication, vessel maneuvers, safety in handling ground tackle, and proper operation of windlass (if equipped). Anchor should hold with engine in reverse gear at one-half throttle. Raise anchor and get underway smoothly using correct procedures.

41. Describe and demonstrate the correct actions to be taken while under power from the time a person falls overboard until safely recovered.


Under Sail

  • Downhaul or Cunningham
  • Outhaul
  • Boom Vang
  • Mainsheet
  • Traveler
  • Jibsheets
  • Jibsheet fairleads
  • Discuss ways to reduce heeling.

43. Demonstrate correct winch operation, including safety considerations for line tension / breakage, hand / finger position, winch handle insertion / removal, and clearing overrides.

Without coaching or assistance from the instructor, verbalize appropriate commands and demonstrate competence, safety and good seamanship in the role of Skipper / Helmsman during the maneuvers listed below. Honor all aids to navigation and use properly the Navigation Rules. Ensure sails are trimmed correctly and the vessel is in control at all times. Adjust sail controls appropriately as the vessel’s heading changes and wind / sea conditions evolve.

44. Get out of ‘irons’ then select and maintain a given tack and course.

45. Head Up, Tack, Bear Away, and Jibe while pausing briefly at each of the following points of sail: Close Hauled, Close Reach, Beam Reach, Broad Reach, and Run (with sails ‘wing ’n’ wing’).

46. Heave-to and get sailing normally again.

47. While underway, reduce sail area by reefing mainsail and genoa; shake out reef and resume course.

48. As crew, give appropriate verbal responses and perform correct actions during the maneuvers listed above.

49. Describe and demonstrate the correct actions to be taken while under sail from the time a person falls overboard until safely recovered.

50. Lower and/or furl all sails and coil or flake and stow all lines properly.


Return to Dock/Slip

51. Ensure vessel / crew readiness and use the auxiliary engine to bring the vessel smoothly and under control to a stop next to a parallel dock or into a slip; secure the vessel using appropriate lines and fenders.
