  • FIG. 2 is a perspective view of the monocoque kayak 500 hull according to Scott without the waterproof cover taken from the rear and above.
  • a breakdown sit-on and sit-in plastic paddleboat is described in Australian patent application No. AU 2004100379 A4 of Stattery filed on May 20, 2004.

  • FIG. 3 b is a perspective illustration of a prior art joint 310 between the center section 302 and the stem section 301 of the marine kayak 300 of FIG. 3 a after the sections have been separated.
  • the kayak is propelled by a double-bladed paddle.
  • the kayak originally served as a hunting vessel, with the kayaker/hunter equipped with a harpoon.
  • Today kayaks are considered a recreational and/or sport vehicle, in various models, usually suitable for one or two kayakers, suitable for boating in rivers, lakes, seas, oceans and whitewater models.
  • Kayaks are commonly made of Fiberglass, fiberglass with foam core or from a verity of plastics.
  • the second type is the sit-on kayak.
  • the kayaker sits on the kayak, even if there is an indentation in the kayak that can serve as a seat, and draining holes while the kayak is waterproof.
  • the main advantage of this kayak is that there is no place for water to accumulate, thus avoiding the risk of sinking. Its main disadvantage is the usually loose seating of the kayaker on the kayak, if he is not strapped in, resulting in a rather high center of gravity.
  • the term “kayak” and the like refer to a boating vessel that is substantially moved independently by means of at least one bladed paddle, when the kayaker (or kayakers) is inside or upon it, seated, standing, or in any other position, has a bow (the front end), and a stem (the back end).
  • This term also includes vessels known to boaters as: Kayak, Sit-On-Top WaveSki, Dinghy, WaterCraft, and Canoe.

  • the number of seating apparatuses conforms to the number of kayakers for which the kayak is designated.
  • a modular configuration which enables extending the kayak and adapting it to a larger number of kayakers, by adding one or more additional central unit, is also possible.
  • the guiding principle in selecting the external form of the main structural parts of the kayak is designing optimal forms to enable the external form of the hull, the bottom side of the modular kayak, is suitable for achieving kayaking performance that meets the kayak's designation when in kayaking configuration while the external form of the top of each of the main structural parts also conforms to an optimal package configuration, enabling assembly of the main structural part into a stable package with external dimensions that are suitable for storage in small places, or places with a certain limited internal space and opening, such as the internal space and opening of the trunk of a certain make of family car, without detracting from the kayak's performance in water.
