Abstract
This paper deals with the wave pattern and wave resistance of a
slender
ship moving
steadily at supercritical speed in a shallow water channel. Using, successively,
linear
and nonlinear shallow-water wave theory it is demonstrated that, if the
hull form is
adapted to speed and channel geometry according to certain rules, the ship
waves
can be made to form a localized pattern around the ship that moves at the
same
speed as the ship and at the same time the associated wave resistance can
be made to
vanish. In the nonlinear case, the zero-wave-resistance ship hull is derived
from
a KP equation solution of the oblique interaction of two identical solitons.
This astonishing phenomenon may be called shallow-channel superconductivity.
