Hoisting Spar Cont'd.
4.1-2
line. The standing end of the line can be led down the spar to a
position just under t.he gooseneck, and secured with a series of
half hitches. Care must be exercised in lifting the spar so that
the half hitches remain tight and do not slip as they accept the
weight of the spar. As with any crane load, personnel should not
place themselves in a position which would result in injury if
the load falls.
The overhead trim pieces around the mast opening in the deck
should be removed at this time so that they are not damaged as
the spar is lowered through the deck partners.
Completion of Spar Installation
After the spar is stepped, rotate the spar to align the track
fore and aft in the vessel.
The wedges must be driven so the top of the wedge is snug with
the mast, and flush with, or slightly below, the deck boss level.
Use extreme care in driving the wedges to avoid hitting the spar,
which can be damaged by a careless hammer blow. Use a length of
soft wood to direct blows to the wedge rather than attempting to
hit it directly.
After the wedge is fully driven, caulk the seams between the
deck and wedge, and wedge and spar. Bolt the deck collar down with
caulking under the bottom flange and under each nut. Lightly sand
the mast at the collar for better sealant adhesion and then add
silicone. Do not use caulking with a high amount of adhesive
quality (like 3M #5200), as the adhesive will make removal of the
collar and wedge difficult. A tube of silicone sealant RTV is
supplied for this purpose.
NOTE: DO NOT SUBSTITUTE mast wedges other than the polyurethane
wedges shipped with the boat. The use of any other wedges
will void all warranties of the spars. Replacements are
available through TPI.
