Mounting Swivel Cam Cleat and Mount
6
Hold mount where you
would like it on the rear
Aka bar making sure the
top of the mount is completely level. We recommend that the Swivel Cam
Cleat is mounted 4 inches
from inside end of the Aka
bar. (FIG 10)
Secure the Swivel Cam
Cleat Mount using the
provided 1.5’’ self-drilling
screw through the center
hole of the side with three
holes. Do not screw in any
other screws. (FIG 10)
Place the Swivel Cam Cleat
on top of the Mount with the
three holes lining up with
the three unused holes on
the mount. Screw in a 1.5’’
self-drilling screw through
the opposite center hole
on the top of the Swivel
Cam Cleat. This screw will
penetrate the Swivel Cam
Cleat, the mount, and go
into the Aka bar.
Screw in the other provided
5/8’’ screws into the two
remaining holes. (FIG 11)

Eyelet Posts need to be
attached to the rear Aka
bar to allow for trimming of the sail. Use the
provided self-tapping
screws to attach the
Eyelet Posts to the
stern side of the Aka
bars. We recommend
that one Eyelet Post is
placed as far back as
possible on the Aka bar
and the other is placed
directly in the middle of
the Cam Cleat and the
furthest out Eyelet Post.
Do this for both rear
Aka bars.
(FIG 23)
Optional: Attaching Pad
Eyes
If you are having problems with the Halyard
Line snagging on the
kayak, two Pad Eyes are
included to fix this problem. We recommend
installing these Pad
Eyes 2” directly under
the each aka bar to reduce the friction of the
Halyard Line dragging
on the bottom of the Aka
bar. (FIG 24)

This spinnaker works best between a broad reach and downwind run.
Do not use on beam reach or close hauled. (FIG 25)
To hoist the spinnaker, pull on halyard line from the front of the cockpit and cleat off on the Harken block on the front crossbar.
To douse the spinnaker, release the lines from the Harken block and
pull from the line exiting the snuffer bag.
Do not use the spinnaker in strong winds beyond your ability level.
If wind is increasing, douse the spinnaker before it gets too strong.
When using the spinnaker be aware of your surroundings as the
spinnaker will reduce visibility.
When tacking and jibing with the spinnaker, furl the main sail in half
way to avoid it getting tangled.
Depending on your batten length and tension, you may need to cut 1-2”
off of the top batten to avoid snagging the halyard line during furling.
