Abstract: A selectively inflatable kayak of the type having at least one elongated pneumatically inflatable peripheral tube which, when inflated, defines a passenger compartment and relatively narrow bow and stern sections. A flexible cover extends between and at least partially encases the at least one elongated pneumatically inflatable tube to provide a floor for the kayak. The flexible cover or separate bow and stern covers are provided for extending between the at least one elongated pneumatically inflatable flexible tube at bow and stern sections, respectively, the flexible cover or bow and sterns covers being characterized as having narrow regions extending below and further defining the bow and stern regions of the kayak. Bow and stern pillows are provided which are sized to at least partially snuggly fit within the bow and stern sections, respectively, and are provided with stiffened ribs which extend within those narrow regions when the pillows are inserted.
