  In the past, large vessels capable of handling a large number of passengers have been operated on sightseeing courses that go around the canal for the purpose of sightseeing. Then, when a large ship is moored to the landing area and passengers get on / off with the landing area, the position of the landing portion on the ship side is higher than the landing surface on the land side such as a pier. As shown, a stair arrangement or the like is used.

  In addition, in the case where the tip of the deck on the bow side of a large vessel is almost aligned with the height of each landing site, the vessel itself is provided with a landing on the tip side of the deck of the bow, and this vessel is brazed It is moored so that the entrance is directly connected to the landing.

  Moreover, as shown in patent document 2, the technique which made the boarding side and the stern side the board | plate which made the apron turnable was provided in the technique which concerns on the same large sized ship, as the patent document 2 shows. In this document, it is shown that the bow side and the stern side are directed to the landing, and the jumping apron is lowered and its tip is attached to the landing surface of the landing to get on and off.

  Thus, in a large ship carrying a large number of people, use of the stair system always installed at the landing, or directly connecting the landing on the side of the hull to the landing, or passing the landing apron provided on the hull to the landing It is possible to get on and off as you go.

Public Practical Application 58-122693 Utility model registration No. 3094817

  By the way, in recent years, a passenger who takes on and off at a platform provided on a canal etc., and a plurality of platforms located on an operation course are being carried out using small vessels. It is expected to grow as a new transportation system in the urban area near the canal.

  The small vessels that carry passengers by way of the above mentioned landing are, for example, types of ships such as pleasure boats where cabins accommodating about 7 or 8 passengers are arranged at the center of the hull, In order to make it easy for passengers to get on and off, set the height of the side of the ship on the stern side of the boarding side, and pass a passing board between the boarding side of the ship and the landing side of the landing side. It allows passengers to get on and off.

  And, in order to prevent the step between the small ship carrying the passengers and the landing surface on the land side from increasing, the landing surface on the land side is often in the form of a floating pier.

  However, at the landing site, there is the complication of temporarily getting into the boat after passing through the floating pier located at a position lower from the ground such as the shore and getting on the landing again, and making the landing platform compact by the floating pier. There is a problem that it can not do. From such a thing, there is a demand to be able to get into a ship directly from the land side at the landing and to be able to go up to the ground directly from the ship side.

  Therefore, in view of the above circumstances, the present invention has an object to be able to align the part to be the landing side of the ship side with the landing side of the land side at each landing, and a small passenger directly at the landing The purpose is to provide a small vessel that can get on and off the ground.
