Abstract: An arrangement (100) for underwater activities includes a reservoir (101), which reservoir includes a wall (102) securing a space inside the reservoir (101) to be filled at least partially with water (103). The arrangement has also an opening (104a, 104b) for entering the reservoir, and a container (105) to be filled at least partially with water (103). The container receives the reservoir (101) so that the lower portion of the reservoir including at least one opening (104a) is located under the water surface level (103). The lower portion of the reservoir when introduced with the container is securing together with the container's (105) wall an upper portion (107) of the container, which upper portion (107) supports via the opening (104a) the pressure difference between the upper portion (107) of the container (105) and the space inside the reservoir (101), when water (103) is introduced into the space inside the reservoir.

Abstract: A floating construction (1, 11) includes a vessel (2, 12) partially or fully filled with water and with transparent walls or with walls including transparent sections, and space (3, 5, 6) provided around or partially around the vessel, where the vessel includes at least one opening allowing the surrounding water to enter into the vessel, wherein the space (3, 5, 6) provided around the vessel (2, 12) is enclosed to provide interior observation area for activities taking place inside the vessel.

Abstract: An arrangement for underwater activities comprises at least two spaces arranged one on the other thereby forming a multilayer structure, where at least one space is configured to be filled by the water for water activity. In addition the arrangement comprises a room for spectators. Each of said spaces comprises at least one wall and layer forming together said space. The first space comprises a first set of activity means for underwater activity, and the second space comprises a second set of activity means for activity. At least portion of said walls and/or layers are transparent. In addition the room for spectators is arranged in connection with said spaces and separated from the space by the wall and/or layer structure.

Abstract: An apparatus for underwater activities including a vessel filled fully or partially with water, which vessel includes one or more open openings for entering the vessel, wherein the lower portion of the vessel is located within a body of water, all of the one or more open opening for entering the vessel are located in that portion of the vessel which is located under the surface level of the body of water, and that walls of the vessel are transparent, or the walls include sections that are transparent, for allowing observation of the activities taking place inside the vessel from outside of the vessel.
