Description

Floating boat {VESSEL SYSTEM}

The present invention relates to a buoyable boat equipped with a heating unit and having a center of gravity aligned with the lower end of a ship.

As maritime traffic becomes more active and fishing activity increases, the number of incidents of ship sinking is increasing. Any type of ship cannot be free from sinking, and recently, as ship safety accidents occur frequently, the inspection and development of safety devices inside the hull is a concern. resulting in personal injury. Various types of lifesaving equipment (lifeboats, life tubes, life jackets, etc.) are provided on ships to save people on board, and devices are gradually being provided to prevent overturning of ships.

In addition, in the case of a ship, particularly a car carrier or a passenger ship, the bottom of the ship forms a flat bottom based on the cross section of the ship. In addition, the larger the vessel and the lower the speed of the vessel, the flatter the bottom shape. For this reason, the height and center of gravity of the vessel increase together, making it very vulnerable to sideways sway.
