ABSTRACT:
The present invention relates to a transverse saddle type boat cradle for transversely supporting a boat at fore-and-aft positions. A rectangular base frame structure is provided with a vertical support frame assembly at each end. Each vertical support frame assembly is adapted to assume an upright supporting position. A detachable hull support panel is secured transversely within each vertical support frame assembly. To provide direct engagement and support for the boat, the hull support panel includes an upper support surface or edge that is selectively shaped and configured to generally conform to the shape of a particular boat hull. Thus in a supported position, a hull support panel underlies and engages the supported boat at fore-and-aft positions. Further to stabilize the boat and prevent rotation of the same within the hull support panels, there is provided a keel restraining device that is operative to prevent the keel from moving laterally.
