Abstract
A boat dolly for supporting the stern of a boat. The bow of the boat rests on a pair of longitudinally disposed and transversely spaced-apart ropes that are tied to the frame of the boat dolly. The bow of the boat is supported and both the boat and boat dolly are propelled by applying manual force to the ropes. The boat dolly includes transversely adjustable wheels, transversely adjustable transom clamps, vertically adjustable transom clamps, self-adjusting hull-receiving rails, and provisions for folding to achieve compact storage.

A boat dolly having first and second ends comprising:
- cradle frame means for receiving and supporting the stern portion of a boat,
- a pair of transversely spaced-apart wheels operatively mounted to said cradle frame means;
- flexible supporting and propelling means, comprising two transversely spaced apart ropes secured at one end to said cradle frame means and extending longitudinally forwardly of the underside of the hull of a boat on said frame means for both supporting the bow portion of said boat and propelling said boat and said boat dolly as a unit in response to a pulling force exerted on the other end thereof,
- said frame means having front and rear portions and including two spaced longitudinal frame members and two spaced cross frame members secured thereto, transversely spaced eyelets depending from said frame means and receiving said ropes therethrough thereby spacing said ropes apart,
- an upright strut device hingedly mounted on the rear portion of said frame means for pivotal movement about a transverse axis between first and second positions, in said first position said strut device being upright and in said second position said strut device being folded onto said frame means,
- said strut device including two elongated substantially parallel and spaced apart struts each being provided with a laterally extending elongated stub, a hinge bar hingedly mounted on the rear portion of said frame means for swinging movement about a transverse axis parallel to the axis of said hinge bar, said hinge bar being hollow and telescopically receiving said stubs within the opposite end portions thereof,
- means for releaseably locking said stubs and hinge bar together in adjusted telescoped position;
- and
- said wheels being carried on the lower ends of said struts, respectively.
A boat dolly for manually transporting a boat having first and second ends, which boat dolly comprises:
- cradle frame means, having front and rear edges, for receiving and supporting a boat proximal to one of said ends thereof;
- rear strut means for providing an upper portion that extends upwardly from said cradle frame means and thereby prevents one end of a boat from moving rearwardly, and for providing a lower portion that extends downwardly below said cradle frame means;
- means for pivotally attaching said rear strut means to said cradle frame means proximal to said rear edge, and for permitting said upper portion to be folded toward said cradle frame means;
- a pair of wheels being transversely spaced apart, being disposed for rotation about a single transverse axis that is disposed below said cradle frame means, and being attached to said lower portion of said rear strut means;
- and
- means for locking said rear strut means with said upper portion disposed upwardly from said cradle frame means and with said lower portion disposed downwardly from said cradle frame means,
- said rear strut means and said means for pivotally attaching said rear strut means to said cradle frame means comprising a rectangular steel tube that is horizontally and transversely disposed and is pivotally attached to said cradle frame means;
- said means for locking comprising a threaded fastener for securing said steel tube to said frame means.
