NORTH SAILS IC37, Sailing Manual

Page: 12 / 20

• Move up to windward and start talking with helm
about feel and speed/angles to sail.
• Be ready for the jibe and getting the boat on a
good angle.
5. Trim #2
• Pull pole/tack out if you can do both. Otherwise
pulls tack out.
• Load lazy spinnaker sheet onto winch and make
sure it’s clear for the jibe.
• Move to grinding on winch or get ready to jibe the
chute.
6. Pit
• Eases vang to mark.
• Pull pole out if Trim #2 can’t do both pole and tack
together.
• Tail spinnaker halyard up from weather side deck
(out of cockpit). Make sure jammer is closed!
• Once jibed, ease outhaul and set vang up for
downwind.
• Clean halyards and tack line once settled.
7. Mast
• Bounce spinnaker up from mast. Make call: “3, 2, 1,
made!” Checks halyard marks and move to rail.
8. Bow
• Makes sure halyard is clear and pulled forward.
• Open hatch and make sure sheets are clean and
set up.
• Dig tack out and pull forward and gets out under
jib foot and around pulpit. Keep hold of the head
the chute.
• Help feed head and tack during hoist, keeping
head forward until hoist call is made.
• Check spinnaker on the way up and makes sure
there are no twists or problems with string line.
• Pulls jib down if that’s called.
• Get lazy spinnaker sheet clear and ready for the jibe.
• Close hatch and gets to the rail or get ready to
gybe the jib from on the bow.
9. Floater
• Move forward to be ready to help taking jib down
if it’s jib-down conditions.
• In more wind, move forward to help overhaul jib
sheet. Jib needs to come back on to help tack of
spinnaker around pulpit.
• When it’s windy, stay back in the boat.
Jibing
As on every asymmetric boat, you will find the IC37 has
a style and technique associated with its performance
and the operational side with its winches, etc. Once
you figure out what the turn rate will be to time the
rotation of the spinnaker, you will want to work very
hard to jibe the same way all the time. Use the crew
to work their weight placement and roll the boat
down range with everyone that can move to the old
windward side or even just a step in towards that
side. Also have two or three crew along the rail to
pull (bounce) the new sheet around. The goal of your
steady turn rate is to allow the rotation of the chute to
the new side so the boat hits its speed-build angle just
as the sail pops and you flatten the boat with the crew.
This will be often called by the trimmer, as it will be a
“fast flatten” or a “slow squash” depending on the roll
and turn rate vs. the angle you land on. As the breeze
and waves build, you will find the balance of the turn
rate vs. the spinnaker rotation will need to change. It
will also be affected by how early or late you get the
main across through the jibe. Your style and speed of
rotation and turn will become part of what you develop
to suit your team.
You will have several common styles of jibes:
• “Normal” (VMG) will use the best turn rate for
spinnaker rotation and crew roll.
• “No look” will be used when you want to jibe first,
without the trailing boat jibing also. This as we all
know means the boat gets turned and everybody
plays catch up… Usually people are ready and
holding what they need without showing. I like
to have this where you might have someone that
doesn’t normally do that role but is closest take it
