22. Describe and discuss what to do if
one or both engines fail.
23. Describe options for carrying and towing a dinghy.
24. Describe the method of tying a multihull securely to a dock in areas of varying
Handling Under Power
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).
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.
Maneuver the boat under power in a confined space, noting the effects of wind
28. Maneuver the boat within 2 feet of, and parallel to a dock.
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 the boat in the
opposite direction and compare the differences between both turns.
items 29 and 30 while making stern way (going backwards).
32. Steer a straight
course of at least 10 boat lengths in reverse using moderate speed.
the boat used for certification is equipped with tow engines, repeat items 30-31
using one engine then the other.
34. Steer a multihull using an emergency
steering device, forward and backward on a steady bearing, forward on a figure 8 course
Demonstrate a skippers actions and commands while under power from the time a
member of the crew falls overboard without warning until the crew is safely recovered.
36. Describe at least two methods of getting a person out of the water and back
on board a multihull.
Handling Under Sail/Points
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 jibing, heading up, bearing away and luffing while
noting 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
41. Trim luffing sails noting how long it takes to accelerate to
Demonstrate a skippers actions and commands while under sail from the time a member
of the crew falls overboard without warning until the crew is safely recovered.
Use two different return techniques including the quick-stop method.
Reduce sail by reefing and shale out a reef while keeping the vessel under control
and on course.
44. Heave-to and get underway again, noting the vesselsmotion
at different angles to the wind.
45. Sail with mainsail only, then headsail
only noting performance characteristics and limitations.
Use proper anchoring techniques to anchor using the following methods:
* Two anchors off the bow or stern (Bahamian style)
* Single bow anchor and
* Single bow anchor and stern to the beach (Med style)
* Bow to
permanent mooring with bridle (if available)
* Beaching with consideration
of daggerboard/centerboard, rudder and hull mounted electronics. (optional)
fast and Snugging Down
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.
