#3156 MAST STEPPER III
To ensure proper operation, read these instructions carefully and completely before using the Mast Stepper
III. The Mast Stepper III can be used with your Hobie Getaway catamaran on or off the trailer. If on the trailer,
your trailer winch is used for power. If your trailer is not equipped with a winch, one can be purchased from
your local dealer. For off-trailer, use of a block and tackle is necessary (Mainsheet system).
HARDWARE INSTALLATION The Mast Stepper III requires a few hardware installations on your boat.
A) Install the loop tangs in the forward crossbar castings. 4 threaded holes
are present in the end casting. Use the lower / forward hole (Figure A /
Starboard shown with wing leg in place). Bolt into place using the provided
hex bolts. Position the tang with the loop facing up.
B) Detach the furler system from the bridles. Position the furler to the lower
end of the jib as in its normal sailing position. Install the short stainless plate
in the bottom of the jib furler. The plate sits either to the side of the forestay
adjuster or between the two plates and pins in place using the same clevis
pin used to hold the forestay plate in place. This plate must protrude below
the bottom of the furler drum. This is used to attach to the stepper pole.
USING THE MAST STEPPER III
CAUTION: LOOK FOR AND BE AWARE OF OVERHEAD POWER LINES WHEN STEPPING THE MAST. MAST
CONTACT WITH AN OVERHEAD POWER LINE COULD CAUSE SERIOUS INJURY OR EVEN DEATH!
1) Position the boat and trailer on level ground. If there is some slope, position the bow of the boat downhill.
Best if the trailer is attached to a tow vehicle during stepping.
2) Place the mast in position and insert hinge pin. NEVER ATTEMPT
TO RAISE THE MAST WITHOUT A HINGE PIN IN PLACE. Mast should
be centered on the trampoline.
