ALLY, the foldable canoe,has an interlocking framework of
tubular aluminium stays and ribs held together with spring
loaded shock-cords making the canoe easy and quickly to assemble.At
the bottom,between the framework and the reinforced PVC-skin,there
is a closed cell foam mat that insulates,provides flotation,
and provides the added safety of a double bottom.At the same
time it provides shock absorbency from impact from items under
water.The canoe s flexibility allows it to ride over
waves rather than crash into them.Its flexibility also makes
encounters with underwater rocks a much less harrowing experience
than when riding in a canoe of fiberglass.The reinforced skin
is sewn and welded to achieve extra strength. The anatomic
seats position may be adjusted to trim the canoe.The
DR (Down-River)models features a reinforced bottom which gives
extra safety when paddling on rocky rivers.
Choosing the right canoe:
Choosing a canoe is always a compromise. Some canoes are made
for speed while others are meant to be stable. Stability is
primarly a function of width and bottom shape, with some contribution
from the length of the keel. A canoe with a long flat bottom
will feel stable, and such a canoe will have good initial
stability but a poor final stability. On the other hand, a
canoe with a rounder bottom will have poor initial stability
but good final stability. A canoe with a rounded bottom is
therefore well suited for use in white water. Canoes with
a rounded bottom are the fastest, but will totally lack the
initial stability "feel", which is necessary for
most people to feel safe. Canoes with outwardly slanted sides
have improved stability, but can be a bit difficult to paddle.
Canoes with "tumblehome" (pear shape) are easier
to paddle, but the final stability is worse. Straight side
walls is therefore often a good compromise. The curved arch
which the keel forms between the bow and stern is called "rocker".
A straght keel line without any rocker gives good directional
stability, but the canoe is correspondingly difficult to maneuver.
A hull with extreme rocker will be easy to turn, but diffucult
to paddle straight with. A good alternative might therefore
be a canoe with a partially straight keel line and a little
rocker at the bow and stern. Good directional stability is
now combined with acceptable maneuvering capability.
The new generation Ally folding canoes:
Designwise these canoes differs from previous Ally canoes
in that the tubular aluminium ribs at gunwale, bow, stern
and keel can be connected to make a stiffer construction.
The keel line is straighter and bow and stern lower and the
canoe therefore tracks straighter in windy conditions. Together
with a slightly "slimmer" "tumblehome"
construction a better length/width ratio than on previous
models, this makes the Ally easier to paddle and just as fast
as a canoe made from fiberglass.
