Abstract
An improved kayak has a hull of thermoformed ABS plastic having a bow and a seat having a void between the bow and the seat, a top of the hull being a deck with a foam PVC block glued to a bottom face of the deck. A rotomolded polyethylene plastic insert is located in the void and joined to the hull by fasteners that pass through the insert and the deck of the hull and engage the foam PVC block within the hull, with caulking between the hull and the insert. A propulsion device is removably mounted in the rotomolded plastic insert that allows a user of the kayak to propel the kayak.

An improved kayak comprising
- a hull of thermoformed plastic having a bow and a seat and having a void between the bow and the seat,
- a rotomolded plastic insert comprising a block with a through-hole located in the void and joined to the thermoformed hull by fasteners that pass through the insert and a top portion of the hull and engage a foam PVC block within the hull, and
- a propulsion device mounted in the rotomolded plastic insert that allows a user of the kayak to propel the kayak.
An improved kayak comprising
- a hull of ABS plastic having a bow and a seat having a void between the bow and the seat,
- a polyethylene or polypropylene plastic insert comprising a block with a through-hole located in the void and joined to the hull by fasteners that pass through the insert and a top portion of the hull and engage a foam PVC block within the hull, and
- a propulsion device mounted in the polyethylene or polypropylene plastic insert that allows a user of the kayak to propel the kayak.

A method of making an improved kayak comprising
- thermoforming a kayak deck and thermoforming a kayak bottom, both the kayak deck and kayak bottom having a void between a kayak bow and a kayak seat,
- joining the kayak deck to the kayak bottom to form a kayak hull that has a void between the kayak bow and kayak seat,
- mounting a rotomolded insert in the void, the rotomolded insert comprising a block with a through-hole and configured to receive a propulsion device that allows a user of the kayak to propel the kayak, and
- joining the rotomolded insert to the kayak hull by fasteners that pass through the insert and a top portion of the kayak hull and engage a foam PVC block within the kayak hull.
