| Spinnaker sheet/Spinnaker guy |
The spinnaker is controlled by two "sheets",
but the sheet which is led via the spinnaker
pole is called the guy (or aft guy) and is
attached to the windward clew of the sail.
The sheet is attached to the leeward clew.
The sheet becomes the guy and and vice
versa when the spinnaker is gybed.
The spinnaker pole is attached to the
spinnaker via the guy. The spinnaker pole
must be equipped with both a pole uphaul
and downhaul to keep the pole horizontal.
Note that the spinnaker pole downhaul must
deal with much greater forces than the up-
haul because the spinnaker has a significant vertical
driving force component. Both sheet
and guy is led through blocks on the aft deck
and on to separate winches, often dedicated
spinnaker winches somewhat smaller than
the genoa winches |
