Embodiments are directed to a hybrid frame boat. The hybrid frame boat may include a cover and a drop-stitch port bladder, a drop-stitch starboard bladder, and a keel beam that may each couple to the cover. The cover may have an aft end portion, a forward end portion, a port side, a starboard side, a longitudinal length extending from the aft end portion to the forward end portion. The drop-stitch port bladder may extend along one or more portions of the port side of the cover. The drop-stitch starboard bladder may extend along one or more portions of the starboard side of the cover. The keel beam may extend along one or more portions of the longitudinal length of the cover between the drop-stitch port bladder and the drop-stitch starboard bladder.

The collapsible water vessel is deployed as either a kayak or a canoe. The collapsible water vessel is portable and is stored as or in a backpack. The collapsible water vessel deploys with a bottom configuration selected from the group consisting of a normal bottom, a deep V bottom, and a flat bottom. The collapsible water vessel comprises an outer frame, one or more ribs, one or more seats, an outer shell, a flooring bladder, and a plurality of elastic cords. The outer shell provides a barrier between the interior of the collapsible water vessel and the water within which the collapsible water vessel is placed. The outer frame, the one or more ribs, the one or more seats, the flooring bladder, and the plurality of elastic cords form the physical structure upon which the outer shell attaches.

The invention notably relates to a water surface autonomous vessel having a hull and configured to be connected, through a lead-in cable having a negative buoyancy, to an end of a seismic cable having a neutral buoyancy and adapted for midwater data acquisition, wherein the water surface autonomous vessel comprises a winch for varying the deployed length of the lead-in cable, and the hull of the autonomous vessel forms a conduct at the back of the autonomous vessel in the direction of deployment of the lead-in cable. This provides an improved solution for seismic prospecting in aquatic mediums.

A quick connect system for a boat connects the deck of the boat to the hull of the boat. The deck sits on top of the hull. The hull is preferably inflatable, and preferably in two opposing, symmetrical hull sections being a left hull and a right hull. Each hull preferably has two parallel inflatable tubes that extend from the rear of the hull to the front. The deck is preferably a multi-piece system having a spaced apart front deck rear deck. An elevated casting platform extends between the deck sections and is supported by legs. The hull and deck have a series of aligned rigid tube receivers and loops that receive a series of rails. The rails are slideable into the loops and rigid tube receivers to secure the deck to the keel, and to provide a quick mechanism to disassemble the deck from the tubes.
