The particular form of the invention herein disclosed
is designed ‘and proportioned for use by children and is
intended for the pleasure of swimmers and bathers who
use it as a paddle boat. It will, however, become appar

Referring to FIG. 8, the crank 17 with a journal mem

The body of the vessel as shown in FIGS. 1 to» 6, in
clusive, is molded as a single piece of foam or expanded
plastic material with a smooth exterior surface and of
very light weight. It comprises a forwardly extending
slightly tapered prow It) and a pair ofside walls 11 ex
