By turning the crank both boat and boatman will make
a cyclical movement: The boat falls down the wave, it seems
to sink but then it swims on the top again. The sailor is lifted
from his squatting position while the seagull is sitting motionless
on the top of the prow.

The handle moves a crank slider. The free end of the lever is fixed to the
boatman and carries out an elliptic movement: the boatman jumps up and sits
down again. Because the feet of the boatsman are sticked to the bottom of
the boat it glides back and forth on the crest of the wave.
