Abstract
The specification describes a tow bar assembly for coupling an auxiliary watercraft to the stern of a larger towing craft. The tow bar assembly comprises a socket member especially designed for attachment to the swim platform of the towing craft when one is provided or, alternatively, directly to the transom of the towing craft. The socket is designed to receive one end of a generally longitudinally incompressible but vertically flexible bar member. The other end of the bar member is provided with a suitable coupling device for facilitating connection to the bow of the craft to be towed.
