Build of the Final Prototype of the QT Skiff
for the Family Boat Build, 2013
When last we left the QT Skiff, we'd done some pretty
fun testing with a variety of motors. This testing showed us we
might be able to streamlining the construction process and make
the boat a little lighter.
The forward seat was moved 12" to the front
to better trim the boat when carrying a heavy load at the back
Gunnles and inwales shaved down to 1/2"
thickness to reduce weight
Motor mount board was moved inside the transom
for aesthetics and maybe reducing stress/joint fatigue on the
- - additional change: replacement of exterior skids with internal
'pads' reducing the weight by ~10lbs, making better use of the
plywood, and reducing the Bill of Materials by three 14' 1x2s.
This will probably NOT be incorporated into the final design.
I'd precut the sides, reassembled the frames, and
milled out the sticks we'd be using for the wales at home. You can
get all the sticks you need from a 2x10 or 2x12. The first step
was to plane the wales down to 1/2" thick, then route the corners
off. We saved ~7lbs by doing this. (the chines are still 3/4"
thick - to give us something solid for screwing on the bottom )
Curt and I had just started attaching the sides to
the frames when Greg and Sarah showed up - they'd been vacationing
in Lincoln City and thought they'd drop by.
So I put 'em to work - Greg on the screw gun and Sarah
on the camera.
To help with frame placement, I clearly marked the
identification on each frame, where it was to go, and which way
it was to face.
Attach a forward frame, an aft frame, then the transom.
and get our final boat-y shape when we attach the
stem. Our bow is a little finer than the one designed by Jim Michalak,
he has the stem flared at 30° while ours is more like 25°
- that's what happens when you do away with temporary frames.
We'd assembled the boat 'rightside up' because the
our frames need to meet the top of the side. We then flipped her
and trim off a 1/2" of the frames at the bottom because . .
. for some reason I've decided I want water to freely run back and
forth instead of pooling in specific areas and leading to rot. I
don't know why, but I'm really hot on that idea.
The final step for the night was to attach the chines
- which we did with PL Premium and #6 3/4" stainless steel
And there she is for the night - flipped back over
because I had thought about starting on the wales, but decided I'd
rather have a beer at the Twisted Snout instead. It took us about
an hour and a half to get to this point (we'd spent the earlier
part of the day in prep.)
The next morning, I started by attaching the spacers
to the top of the sides. Bill came by to enjoy the fun.
I take perverse enjoyment in making sure knots and
other 'flaws' in the wood shows - I think it give the boat character.
I must be careful not to allow this perversion to put knots where
they'll be a structural risk.
We glued and screwed the gunnles to the exterior top
of the hull, running the screws into the spacers, then flipped her.
Bob was there, running the camera at this point.
I let the guys play with the hand planer for a while
- so they could 'meditate to the feel of shavings curling off the
Then I took the power planer and planed the bottom
of the chines flat in a couple minutes - I can meditate at home.
Curt smoothed out any wrinkles with the belt sander.
After a bit of fiddling, we got the bottom laid out,
tracing the shape of the bottom onto the plywood, then and Curt
and I cut 'em out.
We started at the bow - a nice, thick bead of PL and
then screwing it down with deck screws.
Again with the PL and then we carefully lowered the
ft portion of the bottom on. This is pretty easy with a little help.
And screws every 5" or so.
Flip (she's really gaining weight now)
Lay out the butt-block and glue for the seam
and screw the butt-block down to a temporary backing
board (covered in wax paper, of course.) We'll fill the screw holes
with toothpicks dipped in glue.
And the final step was to attach the inwales. Why
don't I have a pic of the boat as we left her on Saturday? I have
Next week: Sand, scrape off excess glue, and prime.
