QT SKIFF, ROWING SKIFF, 13' X 45",
75 POUNDS EMPTY
Flat iron skiffs are said to be easy to
draw but very hard to get right. QT is my attempt at a flat
iron skiff. The prototype was built by Paul Krayniak of
Odessa, NY and a photo of his boat is presented below. The
above photo is of Brad Boerger's QT.
I chose a size that will
be easy to cartop and yet ample for two adults. The bottom
is narrow for good rowing but still wide enough to allow
stand-up stability, unlike a dory. The top is wide enough
for good spread of the rowlocks. The result is pronounced
flare at the midsection. But if the flare is carried forward,
the result will be extreme rake at the bow. So I twisted
the first four feet of the side planks to reduce the stem
simple nailed together job from three sheets of 1/4"
plywood. No jigs, no lofting.

POWER QT SKIFF, POWER SKIFF, 13' X 45",
90 POUNDS EMPTY
QT has been around as a rowing
skiff for a long time now and each set of QT rowing skiff
plans includes a set of plans for a powered version of QT.
I just got photos of a completed power version of QT from
Barron Wester of Smyrna, Ga. The photo shows him in his
local waters using a 2.5 hp outboard.
The power QT is nearly identical
to the rowing QT except that its bottom runs straight aft
from the maximum beam, a "straight run" as they
say, with no rocker in the stern at all. This is critical
in a power boat that will be getting some dynamic lift from
its speed over the water (unlike the rowing version whose
lift all comes from "displacement" of the surrounding
water as the boat sinks to a level where its weight equals
the weight of the water it has "displaced"). I
think there are two reasons why the straight run is critical
for a power boat. One is that as the boat speeds up it tries
to climb over its own bow wave and as it does so it lifts
its bow. The boat must have a lot of stern volume or else
it will bury deeply at the stern and its bow will point
to the sky alarmingly. The second reason is that with the
typical outboard motor arrangement, most of the boat's weight
is concentrated in the stern, the skipper's weight being
usually the largest item. Even with no motion a good rowing
boat with its fine stern lines can't handle that weight
back there - its bow would point skyward and its stern dangerously
close to swamping even without starting the motor. The upshot
of this is that a good rowing boat can never be a good power
boat, and a good power boat can never be a good rowing boat.
By the way, power QT would
be limited to about 5hp (maybe less) by the Coast Guard
recommendations, and mine too. If you are lightweight it
may plane with that power.
Simple nail and glue construction
from three sheets of plywood for either version of QT. No
jigs or lofting.
