The day is done and you’re ready to head home but
that four-mile paddle back to the launch is looking daunting. The wind
is at your back so that’ll help a little but still wish you could just
ride that all the way back.
With a simple sail rig it allows anyone to harness
the power of the wind. In this article is a description of a simple sail
rig that can easily be adapted to any kayak and is cheaply made.
This is a simple spinnaker downwind sail design. It
is collapsible for easy storage and also easy to assemble on the water
for use when the winds allow.
In
picture 1 are the three main components of the mast and sail. These
include the lower mast, upper mast and the sail. The mast is constructed
of ¾” schedule 40 PVC tubing. A ¾” PVC coupler is used to connect the
upper and lower mast when assembling the mast to full length. A ¾” PVC
end cap is mounted at the top of the sail and also at the base. At the
top of the upper mast a ½” eye screw is mounted so to have a tell tale
to give wind direction. The sail is constructed of rip-stop nylon, six
feet high and four foot wide at the base.
Picture
2 shows details of the mast rigging. Two ½” eye-screws are screwed into
the lower section of the coupler. This keeps the coupler from coming off
of the lower mast and also gives a location to mount the lower mast
support lines. These lines are five feet of 1/8” Para-cord. At the top
of the sail is a 1 ¼” stainless ring. This is used to clip into a spring
clip mounted at the top of the upper mast. The two lower corners of the
sail have six feet of 1/8” Para-cord lines that attach to cleats mounted
at the cockpit to tension the sail when in use.
Picture
3 shows the mast, collapsed, as it would be stowed when not in use. The
sail rolls up and can be kept in a pouch on the back of the seat or in
some other small container. Picture 4 shows the mast fully assembled but
stowed on the forward deck of the kayak. It still stays out of the way
but is easily
pulled
free and rigged for use. In either form the mast and sail are easy to
store onboard the kayak while under way and can be carried at all times
to be used when the winds permit.
Picture 5 shows the rigging of the mast. A
flush-mount rod holder provides a base for the mast. The mast easily
slips into the rod mount. The lower mast support lines are then pulled
back to the cleats at the cockpit and the sail raised upright and
tensioned. In this position there is no stress on the rod holder itself
and the mast becomes very rigid. Picture 6 shows the mast assembled and
raised without the sail in place. The mast support lines are high enough
to allow for paddling while the mast is in place. Picture 7 is the sail
clipped to the top of the mast and the lower sail lines tied off at the
cockpit to tension the lower portion of the sail.
 
Picture
8 is the sail in use. In this position it is held against the mast with
a bungee cord on the lower mast. This allows for the paddler to quickly
take down the sail and paddle. Picture 9 and 10 show the sail in use.
These conditions were in light, variable winds but still provided enough
to fill the sail. In picture 11 it can be seen that the sail can be
shifted, in this case to the right, in order to catch the wind when it
is not directly behind the paddler. This makes the sail very versatile
as the wind can be quite a few degrees away from a direct tailwind, yet
still provide forward movement. Picture 12 shows that the sail does
interfere somewhat with forward vision but is narrow enough to lean to
one side or the other to view what is in front of the kayak.
 
Adding
a sail to your kayak can be a great advantage. In most cases the wind
will favor your trip in one direction or the other. Being able to ride
the wind for one way of the trip allows for longer-range trips that are
faster and less stressful on the paddler.
