48. Sail a steady compass course, varying the heading no more than +/- 10 degrees, with sails trimmed properly.
49. Demonstrate proper usage of all lines and sail controls (halyards, sheets, traveler, boom vang, outhaul, downhaul, etc.) that are available on the catamaran to obtain maximum performance and comfort.
50. Demonstrate proper combined usage of the mainsheet and traveler for upwind and downwind sailing.
51. Demonstrate how to get out of “irons.”
52. Perform each of the following maneuvers separately and under control, giving appropriate commands and ensuring proper sail trim:
53. Hold a steady course on each of the following points of sail, ensuring proper sail trim:
54. Luff sails while sailing on a close reach at maximum safe speed for the conditions, noting the length of time required for the catamaran to cease making way. Re-trim sails and note the length of time required to accelerate to maximum safe speed.
55. Demonstrate the correct use of a jibe preventer.
56. Demonstrate proper reefing procedures while under sail or hove-to.
