You're referring to image stabilization. I'm unaware of any consumer
camcorders that don't have some form of image stabilization. As it happens,
the HG10 has the same image stabilization as the HV20. It is, however,
designed to minimize shake from hand-held shooting, not the kind of violent
changes of attitude that occur in kayaking. In fact, probably neither the
HG10 nor the HV20 are good cameras for that kind of video as both use CMOS
sensors and are subject to "rolling shutter" distortion.

First of all, digital zoom is not really zoom -- all the camera does is
enlarge a section of the sensor to occupy the entire frame. This result in
significant (really dramatic) image degradation. Second, no person alive
can hand-hold a camcorder at more than 20x zoom (and most people can't at
10-12x either), so this "uber-zoom" is completely useless.

To do any kind of video well, one needs a steady camera. That's why all
camcorder manufacturers include image stabilization (either electronic or
optical).

It's not that it isn't considered as good. It's that it seriously degrades
the image quality.

Ummm, no, they don't. AVCHD results in three distinct kinds of compression
artifiacts, none of which are effected by the optics or any other
"technology" in the camera. Also, there is nothing wrong with AVCHD per se.
The problem is that Canon, just like the other consumer camcorder
manufacturers of AVCHD machines, have arbitrarily limited the bandwidth of
their AVCHD so that motion and compression artifacts are inevitable.

You will. You'll also have trouble finding editing software that supports
AVCHD.

No, you wouldn't. Some cameras are better suited for some purposes. There
are certainly HDV machines out there that would do an excellent job on your
kayak videos.
