Downwind, the crew dynamic changes to better accomadate the use of the
Spinnaker. The foreward crew member runs the bow and gybes the spinnaker
pole without ever leaving the cockpit. The middle Crew Member trims
the spinnaker sheets as the helsman controls the main while steering.
The Spinnaker sheets runs through a 'tweaker' then to a fairlead through
a cheek block in the stern. It is then lead from the stern to a flip
flop block, which allows the the spinnaker to be trimmed at any angle
in the cockpit.
