Stepping the Rig
DANGER! CONTACT WITH OVERHEAD ELECTRICAL WIRES COULD BE FATAL!
PLEASE USE EXTREME CAUTION WHILE STEPPING THE RIG, LAUNCHING AND
SAILING! THE CARBON FIBER MAST WILL CONDUCT ELECTRICITY
•
Align the mast such that the mast step is in proximity to the SS fitting on deck being careful to
support and pad the mast at aft end of boat.
•
Tie together a suitable 20-‐30' extension line to the top of either the main halyard or spinnaker
halyard.
•
Connect and properly pin all side shrouds onto the side chainplates being sure that turnbuckles
are well loosened.
•
Double check that headstay is installed and fittings aligned at the top and turnbuckle is ready to
be pinned to furler tack fitting.
•
Remove the hinge pin from the mast step and arrange mast step over the SS loop of the deck
fitting.
•
This will require someone to lift the mast at the aft end of the boat, and/or can be achieved by
fashioning a support (reference Appendix C: Dec 13, 2013 J/70 Technical Bulletin).
•
IMPORTANT NOTE: IT IS ALWAYS NECESSARY TO SUPPORT THE AFT END OF THE MAST AT
LEAST 20" ABOVE a 2 x 4 support bridging the stern rails in order not to overstress the SS loop
on the mast deck plate when lowering the mast.
•
Lift the mast while a helper pulls the extended spinnaker or main halyard from the front of the
boat.
•
Once mast is up, pin headstay properly before releasing any tension from lifting halyard.
•
Connect backstay with two shackles to the transom chainplates after running Harken backstay
blocks (see backstay diagram).
•
Take up turnbuckles evenly on port and starboard side shrouds until hand tight.
•
