I'm not sure looking like a shoe was one of the primary design
objectives, but does anyone know what the sidecut was all about? Sidecut
works with a ski or snowboard because they are designed to flex when put
on edge. I doubt the Fury flexes enough for the sidecut to have any
effect when carving turns. Perhaps the wider stern had other desireable
effects, but Corran's current designs are either straight-sided (Hammer)
or more conventionally tapered from cockpit to either end. Anyway, the
Fury was probably the first plastic flat-bottomed river boat, so it was
revolutionary in that respect. Make sure you can get in it comfortably,
there is very little footroom for taller paddlers. The only Savage
design we see with any frequency here in the mid-east is the Scorpion,
which a lot of people still like for its speed.

Actually side-cut let's a ski or snowboard turn with little to no
flexing. The more side cut the less flexing is needed to turn....

I've always wondered if sidecut would have an effect on surfing steep
ocean waves.
Say, design a boat that's bottom is flat and cut like a snowboard?
Maybe some one could try it out?
Corran? Necky? Dick Wold? Hunt Johnson?

I don't want to get too far away from boating, here, but if you put,
let's say, a snowboard with sidecut on edge and there was "little to no
flexing", the middle section would just lift up off the surface. The
combination of sidecut, lean angle, and flex allows the edge to form a
curve that approximates the radius of a carved turn. This can only
happen if the board flexes. For a given radius, more sidecut would
require less lean, but without flex, the center will still just lift up
off the snow.
Bringing this back to soft-water sports, notice that surfboards,
waterskiis, wakeboards, etc., all have a certain amount of rocker and are
widest near the center.

What squirt boat has a flat hull? My old Maestro was kinda flat but,
not really. Every other squirt boat so far to date has a rounded hull.
They have been specificly designed this way to make use of Bernoulli's
Principle of lift inverse. This is the primciple of lift in airplane
wings. Turn it upside down and put it in water for a squirt boat. When
the boat slices through the water lateraly, water traveling a greater
distance over the curved bottom opposed to the shorter distance over the
somewhat straight top creates a low pressure and the boat sinks. I've
heard Zit zow is playing with a planing hull on his angest but that aint
no old boat.

mayby the genius behind the fury was that the rocker profile resembles
that of a decambred ski... and then the sidecut is thrown in to boot.

Hi from the cradle of skiing:
Sidecut on a ski only has a purpose if it's riding on a solid surface, like
reasonably hard snow. When you edge the ski and apply pressure, it bends and
the edge CARVES and follows a curved track in the snow-surface.
We seldom handle kayaks in a way that applies enough pressure under the
bottom of the hull to increase rocker, and we don't have a flat surface
for the edge to ride on.
On the other hand, your boat may track better when edged if the ends are
wide due to a longer water-line. This may be interesting. It may also enable
some squirt moves by having more deck surface near the ends to catch water
pressure.

Well, Dave, I certainly don't disagree that the Fury was revolutionary,
as far as plastic boats goes, but the flat hull has been on squirt boats
for many years before Corran came out with the Fury. The fact remains
though that he was the first to take it to plastic and now everyone has
a flat-hulled boat and can do almost anything a squirt boat can do.
(Thank goodness they can't do mystery moves in most of the good
spots-- YET. Probably soon though, eh?) Hell, many of the current
boats -- X, Stubby, Vertigo, etc., are shorter than my squirt boat and,
to a certain degree, more controllable in holes, which I never would've
said five years ago.

This boat cartwheels with ease, squirts in minimal current, and blasts just
about anything! I wouldn't recommend it for steep stuff, but it does boof
without effort!
I've found that in big water it really excels. Some of the best times I've had
in it have been on the Gauley at high water and the New at about 8-10 feet!
Nothing surfs big waves like this baby! It's too fun! Get a Fury but don't
get rid of your old boat just yet!
