| Spinnaker sheet and 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 spinnaker. The sheet is attached to the
leeward clew. The sheet becomes the guy 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 spinnaker pole uphaul and a spinnaker pole
downhaul to keep the pole horizontal.
Note that the spinnaker pole downhaul must deal
with much greater forces than the spinnaker pole
uphaul because the spinnaker has a significant vertical
driving force component. Both sheet and guy are led
through blocks on the aft deck and on to the winches,
often dedicated spinnaker winches somewhat smaller
than the genoa winches. |
