During the winter months 1999/2000 I built
me a Volkskayak (VK). The Volkskayak is a stitch and glue Greenland
style kayak, designed by Gerry Gladwin. It is a hard chined kayak
design
made from two bottom panels, two shear panels, and two deck panels.
It features waterproof bulkheads. 4mm marine plywood, East-System
Epoxy, and fiberglass tape are the main building components. Since
I know my gentle and docile nature I added a additional layer of 6oz fiberglass
cloth to the bottom of my boat -a wise decision.
The
main reason for me to built one of Gerry's boats was the option to built
the break down version, the Volkskomponentkayak (VKK).
I built my boat in one of Gerry's workshops
and he provided precutted plywood panels. My first job was it to drill
the stitching holes into the two bottom panels and the two shear panels.
The first couple of hours I spent stitching the panels with brass wire
to each other. Here the two bottom panels are joint and the shear
panels are partly stitched to the bottom. A spacer wood keeps the
beam with to the maximum beam of 24 inches. A few hundred twisted
wires later the hull had already kayak shape. After installing the shear
clamps -glued in with epoxy and hold temporarily in place with a
couple
of screws from the outside- the front and aft bulkheads were installed.
The bulkheads for my VKK were made from 8mm plywood each. They were
doubled with a sheet of cardboard in between and then stitched in place.
The doubled bulkheads are the secret of the VKK. But first you have
to built the kayak like a regular VK. After I finished stitching
the four hull panels together, and with the bulkheads in space it was time
to fit the deck.
First
the two deck panels were stitched to each other. Than the peak of
the deck was fitted to the bulkheads and the deck shape was fixed with
metal brackets. After stitching everything together the last thing
to do on the first day of work was glueing the panels to each other
with epoxy. The epoxy was supplemented with silica to a peanut butter
consistency. With a putty knife the glue was pushed in all the seams
between the panels to hold them finally in place.
Epoxy
cures in a few hours, and the first thing to do on the next morning was
to pull out all the wires and clean the seams from excessive epoxy.
This is a point were accurate work in the evening saves a lot of work in
the morning. The boat was then ready for the next step. The
inside seams of the boat were covered with 4 inch fiberglass tape and fiberglass
and wood was coated with several layers of unthickened epoxy. The
same procedure was done on the inside of the deck. Putty knife and
foam rollers were used to do the coating.
Then
deck and hull were joined. With lots of thickened epoxy on shear
clamps and bulkheads the deck was fixed with hundreds of screws to the
hull. All the screws were removed after the epoxy had cured.
At this point the spacers for the cockpit coaming were also glued on to
the deck. I choose to built my cockpit a bit narrower and shorter
than the standard VK cockpit. The next big step was to shape the
boat, i.e. to get a smooth and round transition between deck and shear.
After
the epoxy had cured and all the screws were removed the cockpit rim was
glued on top of the spacer. Custom made clamps held the rim in place while
the epoxy cured. With disc grinder, planer and sandpaper a first
finishing job was done to get a smooth, clean surface, and the boat would
have been ready for the final exterior epoxy coating. But this wasn't
a regular VK, it was going to become a VKK!
After I cut the hatch openings into the front and rear deck of my boat,
Gerry handled the jig saw for the dangerous part. I was to nervous
and to afraid to mess it up. The cuts to transform the VK into a
VKK had to be exactly in between the doubled bulkheads. Before the
kayak was cut into pieces we drilled the bolt holes into the bulkheads
and inserted the stainless steel bolts. One reason was to ensure
a good fit later, and to prevent the plywood from breaking under the load
of bow or stern. The result of this operation was an almost
finished kayak cut into 3 pieces.
The
bow section, the cockpit section, and the stern section. Each section
with its own waterthight bulkheads. Now the outside of the bulkheads
was encapsulated in epoxy, taped with fiberglass tape and covered with
fiberglass cloth. An additional coat of fairing compound ensured
a snug fit of the bulkhead surfaces after bolting the boat back together.
Then the outside seams of the boat were taped and the outside plywood was
sealed with serveral coats of epoxy. After a lot of sanding the kayak
was ready for the paint job.
I wanted my boat in bright colors for good visibility on the water.
Therefore the hull was going to be painted all white, with the deck in
red and yellow. But first was a primer sprayed onto the surface to
get an even smother finish. The whole paint job was done with a spray
gun, resulting in an almost fiberglass look. The extensive paintjob
resulted in a very nice looking boat, but also added a couple of pounds
to the total weight of the boat.
My
completly outfitted kayak, with seat, backrest, foot braces, bilge pump,
knee and thight braces comes to a total of 55 pounds. Heavy compared with
the single piece VK (30 pounds) but still competetive with many commercial
plastic and fiberglass boats. Since it was still winter when my kayak
was finished and there was no way for sea trials I started to add artwork
to bow and stern. Even if the Haida never paddled kayaks, I like
their art and legends. The raven plays an important role in their mythology
and I choose the raven to grace my kayaks bow. Instead of a Haida
canoe he is paddling a VK. Later I added an eye and whale to the
art collection, still thinking about other motives.
Spring
was reason to
assemble my VKK for the first real paddle (pool sessions doesn't count).
Before heading out to the water the kayak needs to be assembled.
After carrying the 3 pieces from my apartment to the elevator and from
the elevator to the park deck is handyman time. It takes roughly
20 minutes to tighten the 12 nuts with the wrench. The yellow
discs are gaskets made from 3mm close cell foam to prevent water creeping
through the threads and bolt holes. They are simply pushed over the
bolts and sit between the bulkheads.
I
think they are not realy a must, since in one of the pool sessions I forgot
to put them in and nothing happend. The bow and stern compartments
were bone dry. The bolt in the front end of the cockpit are glues
in. The nuts are placed and thightened through the front hatch cover.
The bolts to connect cockpit and stern are not glued in. This would
prevent it to store the pieces standing upright.
But it is anyway much easier to join stern and cockpit, because the bulkheads,
bolts, and nuts are easy to reach through cockpit
and
rear hatch. After the assembly the only thing left to do is to tie
the kayak thigh to the car rack, load the paddling gear and head for the
water.
