Abstract: A marine railway has a carriage pivotally connected to a support frame near the front of the carriage, and on a transverse horizontal axis. The rear of the support frame is carried by compression springs resting on the carriage. The support frame is provided with support abutments that are adjustable to accommodate the contour of the boat. A cable loop extends from a submerged pulley at the outer end of the railway, and engages a winch activated by a remote control unit. The carriage is interposed in one side of the loop.
