Building a Tik-Tak Kayak

This boat is designed specifically to be quick, cheap, and easy
to build. Two sheets of cheap plywood (exterior grade, or at least
moisture resistant,) a cheap 8' 2x4, and two tubes of PL Premium.
I dug through the pile of 2x4s at Lowes until I found one that
gave me enough clear wood to rip (2) knotless 1x2s from it.
I ripped those (2) 1x2s into the (4) 1x1 stringers (actually just
a hair bigger than 5/8 x 5/8) needed for the chine logs.
From the remaining piece of 2x4, I ripped the stems and (2) 9"
1x2s that will be used as stanchions to support the deck.
Probably the most important thing to do is clearly mark the centerline
on the inner face of the plywood. During assembly, everything starts
at the centerline.
This is NOT an approved method of ripping plywood. Mr. Scheidamann
(my 7th grade shop teacher) would have kicked my a$$ for doing this.
(I learned this method from my father, who was not a shop teacher)
Lining out the sides
I am a firm believer in making all my mistakes at once, so any
chance I have, I clamp pieces together for cutting. I clamp the
sides together and when I drill pilot holes for the screws, I clamp
the deck and sole together as well. Why measure twice when you can
cut once?
No matter how carefully you cut, you never get everything perfect.
The skegs are made from the remainder after cutting out the sides
- glue and clamp them together, then smooth the mating face and
shape the skeg once the glue has cured.
1" drywall screws with pennies for fender washers. Why pennies?
Because the last time I bought fender washers, they were 11 cents
each, and a penny is just a penny (with a 1/8" hole drilled
in it.)
This took me by surprise: The wood I was using for stringers was
very damp ("Green Doug Fir") and as such, didn't allow
the TiteBond III glue I was using to dry. When I removed the screws,
the stringers just popped off.
I switched to this version of TiteBond which I hadn't seen before
- mostly because no one on the coast sells PL Premium, but also
because the label says "epoxy-like strength" which is
probably akin to how frog legs have a "chicken-like" taste.
Polyurethane glues have the wonderful property of being activated
by moisture and also expanding as they cure.
Do you have one of these pull saws yet? Duckworks
sells them, and they are great.
The hatch is an interesting beast. I made it just big enough to
sit inside, back pressed against the aft edge, knees up, and legs
pressed against the forward edge. I wanted it like this to force
the occupant to sit in the center of the boat.
Propping up the sides in preparation of attaching the bottom.
Bottom on! I used screw-clamps on the corners.
I flipped the hull over and installed the skeg (single skeg on
this version, the one in the plans has 2 to help mitigate the squirrliness
problems you get when paddling a very short boat.) You can also
see one of the stanchions in place, and the reinforcing pad made
from the cutout of the hatch.
At this point, a smart man would have painted all the interior,
non-gluing surfaces
I am not a smart man. I didn't paint until after I attached the
deck. The good news is an average-sized adult CAN reach al the places
inside the hull IF he is willing to get a little paint in his hair.
On the first prototype, I didn't have a coaming. That was scary,
as every little splash that came over the bow looked like it was
going to come inside the boat. I'd never made a coaming before,
so I took to inventing. I used the remainder of the 2x4 to make
a bunch of short 1x2s that I held against the underside of the hatch,
traced the opening, then cut with a bandsaw. Look inside the boat:
To get eh remaining plywood to bend, I cut a series of shallow grooves
into the B face, 1/2" apart. I cut them almost all the way
through - just the last ply was holding the stick together.
Holy monkey, it worked!
I did 2 layers of ply, the tried filling the little grooves with
caulk.
OK, why do all this? Because it looks friggin' COOL, that's why.
Like something from the Jetsons.
Top front view. Sweet.!
I took a 3/8" roundover bit to the edges and finished up with
an angle grinder with a 40grit pad for final shaping.
and then . . .
I decided not to paint the exterior before I tried it out - if
it didn't work well, I'd just toss it on the burn pile. There'd
been some skepticism as to how easy it would be to enter (most people
thinking it would be impossible. Note: Look close: I have a PFD
in the cockpit for me to sit on - makes it comfy.
It was shockingly steady and easy to enter. I'd really expected
it to skitter or heel badly. Nope - just get your legs in and sit
down.
Notice the trim: I'd wanted to be just slightly aft of center so
the bow was a little higher than the stern, but still neither end
in the water. PERFECT. I weigh 200lbs and at 5' 10.5" am exactly
average for an adult male for height. Comfortable seating AND the
boat floats well.
Not content with just my happiness, I had Curt give it a try.
He said "It doesn't suck" and suggested adding the second
skeg you see in the plans. All in all a successful, cheap, easy,
quick-to-build design.
