Backbone
A stiffening spine for use in a selectively inflatable kayak. Inflatable kayaks are characterized as having an elongated pneumatically inflatable peripheral tubes which, when inflated, define a passenger compartment and relatively narrow bow and stem sections. A flexible cover extends between and at least partially encases the elongated pneumatically inflatable peripheral tubes to provide a floor for the kayak. A spine for stiffening the inflatable kayak is provided in the form of a relatively rigid longitudinal member and end caps fitted to both ends thereof. The longitudinal member is sized to be removably inserted within the flexible cover so that when installed, the end caps are positioned proximate the bow and stem sections of the inflatable kayak.
1. In a selectively inflatable kayak comprising at least one elongated pneumatically inflatable peripheral tube which when inflated, defines a passenger compartment and relatively narrow bow and stern sections and a flexible cover extending between and at least partially encasing said at least one elongated pneumatically inflatable peripheral tube to provide a floor for said kayak, the improvement comprising a spine for stiffening said inflatable kayak, said spine comprising a relatively rigid longitudinal member and end caps fitted to both ends thereof, said longitudinal member being sized to be removably inserted within said flexible cover so that when installed, said end caps are positioned proximate the bow and stern sections of said inflatable kayak.
2. The spine of claim 1 wherein said relatively rigid longitudinal member comprises a plurality of sections capable of being disassembled from one another for storing and carrying said spine.
3. The spine of claim 1 wherein said longitudinal member is at least partially coated with a cushioning layer.
4. The spine of claim 1 wherein said longitudinal member, when removably inserted within the kayak positions said end caps between said elongated pneumatically inflatable peripheral tube and said flexible cover proximate said bow and stern sections.
5. The spine of claim 1 wherein said relatively rigid longitudinal member comprises a plurality of sections capable of telescoping within one another for storage and carrying said spine.
6. The selectively inflatable kayak of claim 4 wherein said spine creates a bulge in the bottom surface of the kayak.
