I know someone who uses one routinely on Pine Barrens Rivers here in NJ. In
shallow water I've seen him go over logs without incident.

I'm sure it can be done. You'd see the log, know when it would hit,
and pause the pedals for an instant in a retracted state until you
passed over it. It's my opinion that, if you plowed it into a hard
object, then you would usually damage the drive unit. Something
similar happened to the Titanic.

You're correct on the "bracing" issue; however, I usually pedaled with
a paddle in hand. (We finally installed an ama, so it's moot.)

My main gripe is that the moment of my body mass has rotated slifhtly
upwards.
