for which this becomes necessary depends on your main-
tenance and the climate and conditions in which the boat
is sailed. For example: If you sail in the Caribbean, it
should be replaced every 3-4 years compared to every 10
years for the Great Lakes. You should consult a profes-
sional rigger for advice.

Running rigging should be periodically inspected for line
degradation and replaced as needed.

anism in the furling mast should be regularly washed,

through the main bilge floor panel in the main salon.
Adjustments musts be made with deep sockets, sizeable
