  • Patent number: 4883014
    Abstract: A marina having a main walk buoyantly supported on main flotation elements, with the main walk providing access to one or more finger sections buoyantly supported on finger flotation elements. The main walk and the finger sections are each formed from spaced frame members having sunken shoulders which support transversely extending deck elements which define walking surfaces flush with the frame members. Each main frame member may be formed from a plurality of main frame elements disposed in end-to-end abutment. Each pair of main frame elements is joined by a structural element having spaced main frame plates which may engage each main frame member of the main walk. The main frame plates may be interconnected at their edges by a tying member which extends below the main walk.

  • Patent number: 4190013
    Abstract: A floating storage facility for storing small boats not greater than a predetermined length. A floor system comprising a network of longitudinal and lateral support members disposed over flotation blocks provides support for the building. A pair of spaced parallel weight supporting beams are disposed centrally over the flotation members on each side of the storage facility. The parallel beams support a plurality of columns which support a pair of parallel spaced crane runway rails disposed along the upper portion of the building. The weight of the building is distributed over the flotation device to provide a central stabilized loading point for the building. The building has a lightweight metal frame cover disposed overwardly with the outer walls.

  • Patent number: 4070979
    Abstract: A floating storage facility for storing small boats not greater than a predetermined length. A floor system comprising a network of longitudinal and lateral support members disposed over flotation blocks provides support for the building. A pair of spaced parallel weight supporting beams are disposed centrally over the flotation members on each side of the storage facility. The parallel beams support a plurality of columns which support a pair of parallel spaced crane runway rails disposed along the upper portion of the building. The building is designed such that the weight of the boats and cranes are supported by the columns which bears on the flotation device to provide a central stabilized loading point for the building. The building has a lightweight metal frame cover disposed overwardly with the outer walls which is cantilevered out from the front boat support members.
