Headbox C211-C304 and F212-F305 The headboxes are equipped with a new type of separator, to make it easy to access
the top sheaves. Just loosen the separator,
which also works as a locking plate, and
the sheaves can easily be lifted up for
inspection or replacement. This means
that you can replace the sheaves without
unstepping the mast and removing the
headbox. The separator is slightly angled
at its front end to lead the
spinnaker hal-
yard on to the sheave. The headbox fitting
has a gently rounded halyard lead for a
masthead spinnaker or gennaker.
Conventional spinnaker arrangement with
one or two halyard blocks is, of course,
still an option.An instrument base is available for both straight and angled tops. The instrument
base is designed to make it easy to dis-
mantle the mid section when you need to
access the mast top sheaves. Well organised and easily accessible. Separator locks sheaves and also con-
trols spinnaker halyard. Top access, without unstepping the mast and removing the headbox. Mid section of instrument base easily removed to access top sheaves. 1617 >
