Multihull Sailing - BVI Cruising Catamaran Course
Catamaran Sailing Instruction and Certification
Prerequisites: Basic Keelboat, Basic Cruising, and Bareboat Cruising/Bareboat Charter.
For recreational sailors interested in sailing as a family activity, or for sailors that just prefer the feel of sailing on multihulls, cats are the growing boat of choice for many. Catamarans offer spaciousness, comfort and no heeling. The cruising catamaran course covers terminology and hardware identification specific to cats; identifying the differences between multihulls and monohulls, including systems, boat handling under power and under sail, person overboard, heavy weather sailing, anchoring and docking the boat.
This certification course should provide you with a strong foundation for multihull sailing and is achievable in 1-2 days if your Bareboat Cruising pre-requisite has been met. Alternatively we do offer this course in our group course offerings (4 student maximum) in our 6 day/5 night Live Aboard Cruising format. To view a sample itinerary.
Private courses are also available. To schedule private instruction, charter your catamaran through RSSS for 5 days or longer and book your cruising cat course instructor for five days and then continue on to bareboat charter. If you have achieved your Bareboat Cruising certification prior to this course, you have the option to schedule your instructor for the first two days and then continue on to bareboat charter.

A certified Sailor has successfully demonstrated his or her ability to:
Boat Handling Under Power
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 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.
31. Repeat 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.
33. If 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.
- Moving forward on a steady bearing
- Moving backward on a steady bearing
- Moving forward on a figure 8 course
35. 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.
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 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 to rest.
41. Trim luffing sails noting how long it takes to accelerate to full power.
42. 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
Points of Sail
43. 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 vessels motion at different angles to the wind.
45. Sail with mainsail only, then headsail only noting performance characteristics and limitations.
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 permanent mooring with bridle (if available)
- Beaching with consideration of daggerboard/centerboard, rudder and hull mounted electronics. (optional)
Making fast and Snugging Down
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.
