I'm pretty sure the effects of the reflected bow wave are at depths less
than half the waterline
length of the boat.  Which is why I suggested 10 feet (3 meters) being a
good depth requirement for trials.

3'-4' is very noticable.  I find I'm a lot more sensitive to the effects of
water depth when I'm
in the bow of a tandem racing canoe than on my surf ski or in sea kayaks.
In the tandem canoe I'm convinced I notice the effects of water depth at
about 8'.  Now if John Winters were around he would definitely dispute this
"feeling" of a difference at depths that deep.
