While stabilizing the kayak is important, there are a number of other
factors which impact stability.  First, the shutter speed can compensate
for some minor boat movement; the faster the shutter, the less visible
movement in the image (the drawback to fast shutter speeds, is a decrease
in the depth of field [the amount of area in front and behind the primary
subject which will be in focus]).  Second, the speed of film you are using.
Faster films will permit you to use a faster shutter speed and thus reduce
movement.  Today's fast films are very good.  Third, the focal length of
the lens will impact movement.  The longer focal length lenses are
naturally more difficult to use handheld.  Again, a fast shutter speed
becomes almost a given using say a 300mm lens.  Finally, there is your own
ability to hold the camera steady for the duration of the exposure.

Another option, albeit expensive, is to use one the canon lenses with image
stabilization.  I have never used one but the writeups are impressive.  And
they are expensive.

With regard to waterproof camera or housings, I have successfully used an
EIWA flexible housing with my Minolta 7xi and 28-80 zoom lens.  The housing
costs around $190 from large NYC camera stores.  I have used the camera and
housing above and below the water with good success.

Good luck,
sid
