BACKGROUND

Technical field

[0001] The embodiments herein are generally related to a watercrafts system. The embodiments herein are particularly related to submarine systems. The embodiments herein are more particularly related to submarine watercraft systems for recreational, educational and amusement purposes.

Description of the Related Art

[0002] A watercraft is a water-borne vehicle such as a ship, a boat, a hovercraft, and a submarine. The term watercraft conventionally implies to the water-borne vehicles that has propulsive capability (whether by sail, oar, or engine), and hence is distinct from a simple device that merely floats such as a log raft. The watercrafts are used for various purposes/applications such as military, defense, scientific research, marine diving, recreation purposes, etc.

[0003] The conventional recreation watercrafts are used by civilians to discover the universe/marine world underwater. The conventional recreation watercrafts are operated entirely under the water or float on the water. The conventional recreation watercrafts are used for purposes such as underwater tourism, discovering interesting underwater locations, etc. The existing recreational watercraft are of complex structure, bulky, and expensive. Further, the conventional recreation watercrafts incur a very heavy maintenance cost and operating costs.

[0004] Hence, there is a need for a recreational, educational and amusement submarine watercraft that is constructed from cost-effective and relatively inexpensive materials. Further, there is a need for a recreational submarine watercraft that requires less maintenance, and has easy built-in structure. Still further, there is a need for a recreational watercraft that is capable of operating both under the water and inside the water.

[0005] The above-mentioned shortcomings, disadvantages and problems are addressed herein and which will be understood by reading and studying the following specification.
