Gybing the Spinnaker
written by Pat Dolan appearing in LSC's Crew Notes May 23, 2003.
Gybing a Lightning spinnaker
while keeping it full and the boat going full speed is always a challenge
to the entire crew. Everyone needs to work together. Here is a suggestion
on how to get the coordination necessary for a smooth gybe.
After alerting crew members
to the coming gybe by saying "prepare to gybe," the skipper
gets things going by saying "rotate":
||Turn the boat smoothly and gradually to head
almost directly downwind. Coordinate with the spinnaker trim to keep
the spinnaker full.
||Adjust twings so the sheet and guy are about
15 inches above the deck just behind the shrouds - then get ready
to trip the spinnaker pole by grabbing the line underneath the spinnaker
pole with the fist of one hand while hold the pole with your other
||Rotate the spinnaker around the boat so the
pole is back almost to the shrouds and the leeward clew is about 24
inches in front of the shrouds. When fully rotated, and forward crew
is in position, say "TRIP" to initiate the next step.
||Keep the boat headed almost directly downwind.
||Turn your fist so that both ends of the spinnaker
pole are released at the same time. Push the pole up with the other
hand. If both ends of the pole don't release, get the pole off the
mast ring first - then off the guy.
||Keep the spinnaker full and drawing. This
should be possible without moving either the sheet or guy very much.
||Turn the boat very slightly to gybe (to almost
directly downwind on the other gybe) while pulling the mainsail across
the boat. Duck.
||Duck under the boom.
||Duck under the boom. Keep the spinnaker full
and drawing with small trim adjustments - however, keep the new guy
forward of the shrouds at least 24 inches.
||Keep the boat steady almost directly downwind.
||Attach the pole to the new guy - then push
that end of the pole forward so the corner of the sail. Attach the
other end to the mast ring. Say "MADE" when everything is
||Keep the spinnaker full and drawing. Since
the boat is headed almost downwind, this should be possible - even
without a spinnaker pole. In heavier air, it may be necessary to coordinate
an ease of the guy with the forward crew's effort to attach the pole
at the mast ring.
||Keep the boat steady - don't be impatient.
||Smoothly release the leeward twing. Then adjust
the windward twing to the desired height in coordination with the
||Trim in coordination with twing handling by
the forward crew..
A couple of key points are worth emphasizing.
- Rotating the spinnaker is critical. The pole
must be all the way back before the trip. This makes it easier to release
the pole from the guy.
- The leeward clew of the spinnaker must be forward of the leeward shrouds
before the trip. This enables the spinnaker to stay full during the gybe -
and it makes it easy for the forward crew to set the pole on the new guy.
- Getting the twings in position helps control the new guy so that the forward
crew can easily get the pole set.
- Heading the boat almost directly downwind is essential to bringing the pole
all the way back before the trip while keeping the spinnaker full.
- Holding the boat almost directly downwind before the gybe gives the forward
crew time to complete the trip and be ready to duck under the boom.
- During the gybe, turn the boat very little. Keep the boat headed almost
directly downwind - but on the new gybe. This enables the middle crew to keep
the spinnaker full and the boat under control while the pole is being set
on the new gybe. If the skipper changes course to a reach too early, getting
the pole on the mast ring will be a problem in higher winds.
- Coordination between the forward crew and middle crew on twing adjustment
- particularly after the gybe - will help keep the spinnaker well trimmed.
For exampled, pulling the windward twing down without an adjustment in the
guy will pull the pole back. Work together on this - and make the adjustment
smoothly, particularly in light air.
