•
Tie together a suitable 20-‐30' extension line to the top of either the main halyard or spinnaker
halyard.
•
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.
•
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 after running Harken backstay blocks (see backstay
diagram).
•
Take up turnbuckles evenly on port and starboard side shrouds until hand tight.
•
Install boom vang lug
After Stepping the Rig
•
Rig a piece of elastic chord to the port side lower shroud, approx. 1-‐2’ below the spreader, then
pass it in front of the mast and secure to the other lower shroud. This helps “prevent” the
spinnaker from catching (during the hoist) in the triangle created by the mast and the lower
shroud (at the spreader).
•
Set-‐up mast base blocks
•
Install boom
