STEPPING THE MAST . DANGER - Do not attempt to step the mast in an area of low overhead wires. A mast contacting an electrical wire could be fatal. 1. Secure the four trapeze wires near the bottom of the mast so that they will be out of the way while the mast is being raised. 2. Attach the jib halyard line to each end of the jib halyard wire to for[...]

4. With the hinge in place over the step insert the mast step pin through the entire assembly so that it is visible on the opposite side on the hinge. 5. Attach the bridle wires to the bow tangs. Attach the roller furler mechanism between the bridle wires. Make sure the oblong hole in the roller furler is aft. See Figure 18. 6. Attach the port shro[...]

13. Lace it through the rope lock and then through the thimble at the end of the trapeze wire. Now tie the line onto either end of the dogbone. See Figure 23. 14.

Hobie 18 and SX18 UPDA TES INSTALLING THE RUDDER ASSEMBLY The rudders were updated after 1987. The newer rudders use a black plastic cam to lock the rudder in the down position. Locate the left and right rudder assemblies. The left one has a red dot and the right one a green dot. The tiller arms should have a slight bow towards the centerline of th[...]

13 RUDDER AND TILLER CROSS BAR INST ALLA TION (Pre 1987 boat s) 1. Disengage the tiller arm from the lower casting and lock the tiller arm and rudder in the kicked up position. This will pull the rudder blade up and out of the way so the rudder pin can be installed. 2. Hold the lower casting up to the transom of the boat and fit the casting over th[...]

14 RAISING THE SAILS 1. Point the boat into the wind before you begin this operation. 2. Lay the main sail out on the trampoline. Insert the battens into the batten pockets starting at the top of the sail and working your way down. The batten has a tip on each end. The end without any holes goes into the sail first. Slip the batten in until it seat[...]

10. Attach the three boom blocks to the hangers on the boom. Secure the ratchet block to the top of the traveler car. Thread the mainsheet through the blocks as shown in Figure 37. Slip the other end of the mainsheet through the traveler jam cleat, then guide the line through the center of the traveler, and secure at the dead eye on the back bar. 1[...]

16 Raising the Jib 1. Attach the shackle on the end of the jib halyard wire to the head of the jib. 2. Wrap the luff pocket of the jib around the forestay and engage the zipper an inch or so. Next thread the jib halyard line inside the luff pocket. See Figure 38. 3. Raise the sail by pulling on the jib halyard line and at the same time advance the [...]

DAGGER BOARDS 1. Slip the shock cord through the hole in the upper portion of the dagger board, take both ends to the hole on the out board deck flange.

26 SAILING YOUR HOBIE 18’ Safe and sane guideline for the beginner; and an easy review for the experienced. Always wear a life jacket when boating. BALANCING THE BOAT When sailing, sit on the upwind side of the boat (wind on your back) just in front of the tiller, facing the sail. Balance your weight further outboard as the boat begins to tip or [...]

27 TURNING To tack or turn the boat into and across the wind to the opposite direction (also known as "coming about"), follow the points of sail guide illustration and take the boat to the close hauled point of sail. This is when you are nearly 35 degrees from sailing straight into the wind. With the boat moving forward and not stalling, [...]

28 line while slowly leaning back away from the trampoline. Lean to approximately 45 degrees for best leverage. As the mast and sail lift out of the water and the upper hull begins to drop back into the water, drop down to your knees then into the water. Hold onto the righting line near the crossbar or the crossbar itself near the hull that you wer[...]

29 6) Hobie Cat rudder blades are preset to break away from the locked down position at 17-26 pounds by testing with a line around the rudder blade seven inches above the lowest tip of the blade. Once the rake is changed, the breakaway tension should be rechecked. The tension may be adjusted by turning the 3/4" internal screw in the housing. T[...]

A good anti-fouling paint can be applied for some protection from marine growth before mooring. Before painting, it is suggested that the area be masked off to ensure a clean line. No friction reducing paints or agents may be employed on a Hobie Cat during competition. HOBIE CLASS ASSOCIATION The Hobie Class Association was started by a group of Ho[...]

About your Hobie 18’ There are ways of going faster on a catamaran, while still staying within the eight foot beam, trailerable size range. Basically, you put a taller mast on, use daggerboards, and go to a half round hull shape. The Hobie 18 is the end result of our efforts - mine, Phil Edwards' (my longtime friend and co-designer of the 18[...]

CA UTION / SAFETY TIPS • Watch for overhead power lines. Never rig, trailer or sail the boat near overhead power lines. Contact with a power line could be fatal. • Install Drain Plugs. Even the most experienced of boaters forget to install the drain plugs sometimes. When installing the plugs, be sure that the threads and gaskets are free of san[...]
