12. Describe the effects of windage on close-quarters maneuverability under power.

13. Describe the effects of windage on sailing performance.

14. List differences in sailing performance between a monohull and a catamaran of similar size.

15. Describe how to use the jib to counteract the weather-vane effect of a catamaran’s mainsail when tacking.

16. List various sail combinations utilized on a catamaran and how they affect the center of effort.

17. List differences between the mainsails of a monohull keelboat and a catamaran.

18. Describe indicators for and conditions under which a catamaran’s sails should be reefed.

Catamaran Systems

19. List differences in the types of boat systems typically installed on monohulls versus catamarans.

20. Describe freshwater and fuel storage tank placement and precautions on a catamaran.

21. Describe battery-charging options, including alternators, shore power and generator, and how they affect twin-engine catamarans.

  • Bahamian Moor
  • Mediterranean Moor

Heavy Weather Operation & Emergency Response

28. Describe conditions that may contribute to capsizing a catamaran and practices to avoid capsizing.

29. Describe post-capsize response procedures.

30. Describe where and how to attach jacklines and tethered safety harnesses on a catamaran.

31. Describe how the structure and performance of a catamaran under both sail and power affects the recovery of a person in the water (a.k.a. Man Overboard or MOB).

32. Describe heavy weather sailing practices applied to a catamaran, including:

  • Lying a-hull
  • Heaving-to
  • Downwind speed control

33. Describe actions to be taken if one or both engines fail.

34. Identify the emergency steering tiller and indicate where it attaches to the controlling rudder post.


35. Locate and check the condition of all required and ASA recommended equipment.

36. Perform a routine vessel inspection, ensuring that all systems and equipment are in working order.

Under Power

37. Depart safely from a dock when the approximate wind direction is (a) parallel to the dock and (b) perpendicular to the dock.

38. Demonstrate the proper use of spring lines to pivot the catamaran during dock departure and return.

39. Ensure vessel and crew readiness and use the auxiliary engines to bring the catamaran smoothly to a controlled stop next to a parallel dock or into a slip; then secure the vessel using appropriate lines and fenders.

40. Make way ahead and turn the catamaran in a tight circle, comparing the turning radius between three different engine gear selections:

  • Both engines in forward gear
  • One engine in forward, the other in neutral
  • One engine in forward, the other in reverse

41. Make way astern and turn the catamaran in a tight circle.

42. Steer a straight, controlled course astern for at least five boat lengths.

43. Approach a mark under power upwind, downwind, and with wind abeam, in each case stopping the catamaran within 10 feet of the mark.

44. Approach a mooring buoy (or suitable substitute if no mooring is available), attach to the mooring using a bridle, then cast off from the mooring and get underway.

45. Maneuver the catamaran under power in a confined space, compensating for wind and current effects.

46. Demonstrate the correct actions to be taken while under power to recover a MOB.

47. Demonstrate two of the following anchor/mooring methods as appropriate to local conditions, using correct procedures including hand signals, safety in handling ground tackle, proper operation of windlass and use of a bridle. Raise anchor(s) and get underway using correct procedures.

  • Single bow anchor
  • Fore and aft moor
  • Bahamian Moor
  • Mediterranean Moor

Under Sail

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.

  • Close Hauled
  • Close Reach
  • Beam Reach
  • Broad Reach

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 come to a stop. Re-trim sails and note the length of time required to accelerate to maximum safe speed.

56. Demonstrate proper reefing procedures while under sail or hove-to.
