US 5,051,056 A · Portable boat jacking and rotating apparatus

Abstract

An apparatus for suspending and rotating a boat about its longitudinal axis in either direction, including a pair of movable and adjustable support frames having connecting arms which are designed to rotatably engage the support eyes (also known as ski tow eyes, wench eyes or mooring eyes) on the rear and front ends of the boat. The rear support frame includes a rotatable shaft upon which the rear end connecting arms are rigidly mounted so as to be capable of rotating the boat about its longitudinal axis. The rear support frame also includes a base frame with a pair of extensible legs which are adjustable to support and balance varying sizes of boats. Each support frame includes a hoist for causing vertical movement of the connecting arms which support the boat. The front end support frame is constructed so as to define a passageway therethrough to facilitate removal of the boat trailer upon which the boat rests, once the boat is hoisted therefrom. The front support frame is also constructed with a pair of extensible base legs which are adjustable to support and balance varying sizes of boats. Each frame is capable of being readily broken down into a plurality of pieces for easy storage and transportation, and easily re-assembled when desired.

Dependent claims

An apparatus for use in lifting a boat from a boat trailer and suspending the boat from a support eye at its front end and a pair of spaced support eyes at its rear end, and rotating the boat about its longitudinal axis therebetween, comprising:

(a) a pair of rigid adjustable support members being disposed at opposite front and rear ends of the boat, said support members having a structure which is constructed and arranged to respectively engage the pair of support eyes on the rear end of the boat and the support eye on the front end of the boat when the boat is on its boat trailer so as to support the boat solely thereby and facilitate lifting of the same;
(b) one of said support members including a boat rotating means which is constructed and arranged to engage and controllably rotate the boat about its longitudinal axis in either direction
(c) one of said support members defining a passage way having an axis of passage which is substantially parallel with an axis extending through and between said front and rear support members whereby the trailer may be removed through said passage way;
