An experienced crewmember is now required
to take hold
of the foot of the mast while it is
being raised upright by the crane, and guide it
to the leadthrough in the deck. The mast foot
and tabernacle are designed so that they seat
automatically below deck, and no further
adjustment is needed.
As soon as the mast has been stepped, it
should be secured to prevent it from falling
over. The roller furling system, shrouds and
stays can now be attached in the usual
sequence.

Mast collar for deck leadthrough
Care is required when fitting the mast collar
each time the mast is stepped, as any mistake
will result in leaks around the mast. Fig. 9
illustrates the arrangement. The mast is sealed
off inside (8), and any water that penetrates the
mast drains off through the drain hole (2). A
sealing strip seals the mast between the
section and the collar.
Before the collar is fastened to the deck yoke,
a supporting rubber gasket can be inserted into
the gap and secured with a band clamp. If the
mast is not watertight, water will collect in the
inner cover (6) or run down into the boat
between the mast section and the inner mast
casing (7).
