NOTE
It is important that all tensioners at the stake ends of
the guy ropes are fully backed off before attempting to
raise the mast in the next steps.
4.7
ATTACH HALYARD TO MAST
Locate and attach the halyard pulley end, clip into the top (brown) guy plate, down wind side also, twist
the locking clamps on the mast to the upwind side to avoid catching the halyard on the clamp possibly
flipping it open.
4.8
PUSH MAST UP
Using two people, loosen the topmost cam clamp and push the tube up. Close the clamp. Loosen
the next clamp and repeat this process until all tubes are fully extended. Two persons should now
push up the mast by opening a clamp, pushing up a section, and re-closing the clamp. If there is a
serious wind you may need to station someone directly upwind to provide a counter pull to the winds
push. He will assist by pulling against the wind with the loose guy ropes. After pushing the mast all the
way up, one person should stay at the base of the mast and make corrections on the desired "straight
up" condition of the mast while the other moves to each level of guy ropes, beginning with the 2nd
level (black), and tightening each trio, then moving up (to brown, then to green) until the mast is fully
snug and secured.
WARNING
Two personnel are required to perform the task of
raising the mast. More personnel are required in windy
weather. The additional personnel will use the guy
ropes to provide a counter pull to the wind.
