The present invention relates to a submerged-floating type water house. The house comprises: a first lower side part and a second lower side part formed symmetrically with respect to each other; a first upper side part and a second upper side part formed symmetrically and extending from the first lower side part and the second lower side part; and a front part and a rear part formed in front of and in back of the first lower side part and second lower side part and the first upper side part and second upper side part, thereby forming a rhombic-shaped body and floating in water.

The disclosure provides a wave sheltering vessel used to reduce the significant wave height of waves. The wave sheltering vessel includes a hull, a plurality of anchors, and a propeller system. A length of the hull is greater than or equal to 60 meters. A ratio of the length to a design draft of the hull is less than or equal to 6.5. A ratio of the length to a breadth of the hull is less than or equal to 3.5. A ratio of the breadth to the design draft of the hull is less than or equal to 2.3. The anchors are installed at the hull along a longitudinal direction of the hull. The propeller system is disposed at the hull.

Various embodiments of a submerged submersible sailing vessel are disclosed. Such a submerged sailing vessel may comprise a submersible hull assembly, a keel coupled to and extending upwards from hull assembly towards a water surface, and a wind-catching assembly coupled to and extending upwards into the air from the keel for propelling the submerged sailing vessel. The hull assembly and the keel are submerged below the water surface as the vessel is propelled by the wind-catching assembly above the water surface.

A motion absorbing system and method for a structure includes the coupling of a container to a structure. The container has a liquid disposed therein wherein a ullage is defined above a surface of the liquid. An elastic element is positioned in the liquid. The elastic element has a natural frequency tuned to damp motion of the liquid.
