track according to the Deck Assembly drawing. Make sure the cars will slide
the full length of all tracks.
To mount dead lites drill a 1/4" hole from the bottom of the deck up through
in the proper location. From the top of the deck place the dead light so
that the drilled hole is in the center of it. Scribe a line around the body
of the dead light on deck and cut around the scribe line with a saber saw or
a hole saw. Put a bead of sealant around the dead light underneath at the
junction of the flange, the body and the deck, and bolt through the deck.
For boats with the mast going through the deck, the mast step must be installed
with the boat level. Lay out the "J" measurement on the centerline on deck.
Measure half the fore and aft outside measurement of the mast and add this to the
"J". Drill a 1/4" hole at this point on deck and drop a plumb bob down to the
bilge. Mark the point in the bilge at the point of contact with the plumb bob.
This will be the center of the mast step. Center the mast step on this point and
rotate it to either port or starboard to align it with the centerline. Then
fasten down with the rest of the lag screws. Measure the distance from the center
of the mast step to the center of the panting rod hole in the mast step, then
transfer this measurement on deck and drill the hole on deck for the panting rod.
Make a template of the mast section from plywood and add 1/4" all around. Lay
this out on deck with the center of the template centered with the 1/e" plumb
hole on deck. Scribe around the template. Then, with a saber saw make the cut
out. The 1/9" oversize will allow for wedges when you step the mast.
