| Lazy Weekend Canoe, July 31, 2010 |
|

The lazy Weekend Canoe is a designed to be cheap and easy
to build using materials from your average big box store.
It requires (3) sheets of 1/4" ply and (1) 16ft 2x8 ripped
into (6) 16ft 1x2s, (1) 4' 2x2, and (2) 2' 2x3s
The hardest part of the build is cutting the 2x8 - Mr. Scheidiman,
my shop teacher in junior high, would kick my ass if he saw
me wrestling that effing board through the tablesaw. Of course,
running floppy plywood through a tablesaw is no mean trick,
either, but 'needs must' and all that.

|

Once the sides are cut, I stack them back to back and cut
all the stems all at once. You are either going to save some
time or make a whole lot of mistakes really fast, so think
about it before you start.
|
|

Simple butt joints for making the sides - you could scarf
them together, but that'd take an extra few minutes to cut
the scarfs.
(note: the boat is upside down in this picture)
The sides are held apart and at a 20° angle by the yoke
at the top and a temporary brace at the bottom. Since the
yoke is permanent, I've rounded the edges and sanded it before
installation.
Notice the temporary brace is 1 1/2" from the edge of
the plywood - this is to accommodate the chines that'll be
coming soon.
|
|

Held apart in the middle and attached at the stems, the canoe
starts to take shape.
By now you might have noticed I have drawn lines on the boards.
I'm calling this 'faux planking' because it kind of looks
like the boat is made from planks instead of plywood. You'll
see what I mean.
|
|

I've found it easiest to trim off the stem excess before
I attach the chines and gunnels.
|
|

From building boats designed by Jim
Michalak, I've grown to appreciate external chines.They
make it a lot easier to turn your boat back upright after
a capsize and they work like rubrails, too.
The chines extend above the plywood by about 1/4", then
planed and sanded down to meet the ply - giving a nice, wide
surface for gluing on the bottom.
|
|

Some people like to attach the gunnels before the bottom
- they do this because the thin plywood is fragile, and attaching
the gunnel will protect the edge while the boat is upside
down, getting the chines planed and the bottom attached.
|
|

I forgot to take pictures of attaching the bottom, so here
is the inside of the nearly finished boat. I finished it with
Helmsman
Spar Varnish, which gives the boat a very nice color and
coating. See how cool the faux planking is? Not bad for a
$1 fine point Sharpie from Wal-Mart.
The seats are a simple affair, 9 1/2" wide and braced
with 1x2s. I attached 2x2s to the sides to hold the seats
up, the seats are attached with 2" wood screws (stainless
steel, of course.)
And finally: Notice the black caulking at the edges of the
bottom. This is a DAP
roofing product, applied with a caulking gun. It takes
just over 1 tube to caulk the bottom, inside and out, plus
the keel. I was trying to go for the 'tar' look, like in the
days of old.

Here she is in the water. A friend needed help moving some
gear from his whaleboat to the docks - giving me a perfect
opportunity to test out my canoe.
See how high she rides? With just me in the canoe, it was
a little . . . squirrelly - very light and skittery.
|
|

Here she is loaded with 200lbs of me and another 200-250lbs
of crap.
|
|

The canoe weighs about 70lbs, so there is about 500lbs here
all together. She's still riging pretty well.
|
|

When did I get fat lines on the back of my head?
|
|

Here's a shot of the load: Tools, parts, screws, and just
plain crap.
I don't know why people tow tiny dinghies behind their sailboats
- canoes tow just as easily and are much more versatile.
|
|

There she is sitting on the dock. It sure is a pretty boat.
On the drive home, I had four cars honk and give me the 'thumbs
up.'
|
|

No maiden voyage is complete without a mishap. For me, it
was when I was loading up to go home. I'd set the canoe on
top of the car, then realized I needed my tie-down straps,
which were in the back. I opened the hatch, pulled out the
straps, and turned to set them on the ground. The canoe is
so light, the hatch just lifted up the back part of the canoe
until it tipped enough to slide off the front of the car.
It makes a really neat rumbly sound when it does that. I'm
calling myself lucky on this: That's one hell of a drop-off
in front of the car - that canoe could have kept going 40
feet down to the water below. As it was: No damage!

The Lazy Weekend Canoe seems to be a success. It does everything
I want it to do and is dead easy to build.
Bill of Materials:
- Three sheets of 1/4" or 5mm exterior grade plywood.
- One 16ft 2x8 ripped into six 16ft 1x2s, a 4' 2x2, and
two 2' 2x3s
- ~ 20 oz of TiteBond II or III waterproof glue or (2-3)
tubes of PL Premium.
- 100 (minimum) 3/4" flat or oval head screws, stainless
or galvinized, for attaching the bottom. Another 150 or
so if you want to leave screws in the chiens and gunnels.
- Two tubes of caulk
- ~ 3/4 gallon of exterior varnish to get three coats.
