CRUISING  CATAMARAN (114)

Prerequisites: Basic Keelboat (101) and Basic Coastal Cruising (103).  The Bareboat Charter Standard (104) is also a prerequisite and can be attained either by itself prior to BBC Multihull (114) or in conjunction with BBC Multihull .   In either case, ALL MATERIAL IN BOTH STANDARDS (104 & 114) MUST BE TAUGHT AND/OR TESTED BEFORE 114 CAN BE AWARDED.

    SAILING SKILLS

                                 

  25. Cast off and safely leave a dock with at least two different wind directions relative to the bow (i.e. wind across the stern and wind across the beam. 
  26. Stop the bow of the boat within four feet of a marker while maneuvering under power. Perform the exercise upwind, downwind and with the wind across the beam.  
  27. Maneuver the boat under power in a confined space, noting the effects of wind and current
  28. Maneuver the boat within 2 feet of, and parallel to a dick. Define and carry out a bail-out plan. 
  29. Turn the boat in the tightest possible circle to determine its turning radius.  Twin screw boats will perform the exercise with screws turning in opposite directions and again with screws turning in the same direction.
  30. Repeat item 29 turning in the opposite direction and comparing the differences between both turns.
  31. Repeat item 29 and 30 turning in the opposite direction and comparing the differences between both turns.
  32. Steer a straight course of at least 10 boat lengths in reverse using moderate speed.
  33. If the boat used for certification is equipped with two engines, repeat items 30-31 using one engine then the other.
  34. Steer a multihull using a emergency steering device.
    • Moving forward on a steady bearing.
    • Moving backward on a steady bearing.
    • Moving forward on a figure 8 course

                                                      Person Overboard           

                                

  35. Demonstrate a skipper's actions and commands while under power from the time a member of the crew falls overboard without warning until the crew is safely recovered.  The quick-stop method is suggested
  36. Describe at least two methods of getting a person out of the water and back on the board a multihull.

     Boat Handling Under Sail

    Points of Sail

                                                                                         

  37. Function as helmsman and crew giving correct commands and proper responses while demonstrating the proper techniques of close hauled sailing, reaching (all three points), running, tacking and gybing, heading up, bearing away and luffing. Note the differences and likenesses of sailing a multihull vs. monohull.
  38. Sail an ordered compass course for 5 minutes without varying more than 10 degrees from the heading
  39. Sail a figure 8 course between two buoys noting acceleration/deceleration times and momentum during turns                                                                                     
  40. While sailing at full power, luff sails and observe how long it takes for a multihull to come to rest.
  41. Trim luffing sails noting how long it takes to accelerate to full power.

                                                           Person Overboard                                     

                                                                                                                       

  42. Demonstrate a skipper's actions and commands while under sail from the time a member of the crew falls overboard without warning until the crew is safely recovered.  The quick-stop method is suggested.

    Heavy Weather

    Reefing/heaving-to

  43. Reduce sail by reefing and shake out a reef while keeping vessel under control and on course.
  44. Heave to and get underway again, noting the vessel's motion at different angles to the wind.
  45. Sail with mainsail only, then headsail only noting performance characteristics and limitations.

     

    Anchoring

  46. Use proper anchoring techniques to anchor using the following methods:
        • Two anchors off the bow or stern (Bahamian style)
        • Single bow anchor and bridle
        • Single bow anchor and stern to the beach (Med style)
        • Bow to a permanent mooring with bridle (if available)
        • Beaching with consideration of dagger board/centerboard, rudder and hull mounted electronics. (optional)
     
  47. Secure a boat to various dock configurations so as to provide limited movement and set out fenders correctly.  Take extra precautions to secure a vessel for the night at a dock and at a mooring
