An adjustable step includes a planar surface having an acute angular bend at an off-center portion of the planar surface dividing the device into a first section and a second section. The first section has anti-slip surface disposed upon a topside face. The second section has a rectangular cutout portion that transects an edge of the second section. The step is configured to removably secure about a dock post and remain in position when pressure is applied to said first section.

A movable platform adjacent to a stationary platform and operable between a raised position forming a part of a deck surface and a lowered position at least partially submerged in the body of water. A landing section and walkway section included in the movable platform. A lever arm carried by the landing section and extending underneath the walkway section, wherein the lever arm engages a bottom side of the walkway section when the movable platform is in the raised position, and the lever arm disengages from the walkway section when the movable platform is in the lowered position. A floatation unit disposed on the bottom side of the landing section. An air pump unit carried by the stationary platform, wherein the air pump unit channels air into and out of the floatation unit to change the buoyancy of the floatation unit to raise and lower the movable platform.

A berth for a multi-purpose disaster response ship includes: a quay at which the multi-purpose disaster response ship is berthed; a building located along the quay, including at least one quay-facing gate, and sharing at least one common purpose with the multi-purpose disaster response ship; a horizontal movement restrainer that restricts and permits horizontal movement of the multi-purpose disaster response ship relative to the quay; and a vertical movement restrainer that adjusts a vertical location of the multi-purpose disaster response ship to a specified level relative to the quay and that restricts and permits vertical movement of the multi-purpose disaster response ship situated at the specified level.

A publicly accessible urban beach entertainment complex is disclosed, with a man-made tropical, pristine-clear lagoon as the centerpiece of the complex. The lagoon includes a surf feature and surrounding the lagoon are entertainment, educational, sports, and commercial facilities. The complex has a controlled public access and provides the look and feel of a tropical beach with clear waters and sandy beaches. In addition a method for efficiently utilizing facilities and land that are vacant, underutilized, have limited uses, or that are contiguous to or nearby recreational, educational, sports, or commercial venues is disclosed. The method providing a publicly accessible urban beach entertainment complex with a centerpiece man-made tropical-style pristine-clear lagoon having a surf feature. The method allows for generating revenue and increasing efficiency by pairing vacant sites, underutilized sites, limited use land, or sites that are contiguous to entertainment, educational, sports, and/or commercial venues with urban beach entertainment complexes. The complex preferably has a controlled public access, thereby allowing entrance upon payment of a fee.

A nautical vessel docking and storage system attaches to a nautical structure. A system includes a cradle having support elements that include lower portions, proximate and distal side portions, and proximate and distal side abutments; a vessel securing element; a hinge for each proximate side portion; and a puller for transitioning the cradle between docking and storage positions.

An in-situ bollard tester. The in-situ bollard tester may comprise: a frame, cable, and tensioner. The frame is preferably adapted to mount onto a pier or wharf and around a bollard to provide structural support for the cable and tensioner. The frame may comprise a rectangular frame, pair of hanging columns, and first and second pair of legs. The first pair of legs are coupled near proximal corners of the rectangular frame and are vertically disposed. The hanging columns are coupled near distal corners of the rectangular frame. The second pair of legs are coupled at the lower ends of the hanging columns and are disposed in a horizontal manner. The tensioner may be coupled above the rectangular frame. The cable may fasten to the bollard, and the tensioner may apply tension to the cable at various load angles in order to test the integrity of the bollard.

Embodiments provide a quay wall attachment and a method for promoting biodiversity in a marine environment. The quay wall attachment includes a quad plate and a module. The quad plate is secured to a portion of a quay wall located underwater. The module includes a coral module, a fish module, a plant module, and combinations of the same. The coral module includes living corals and is secured to the quad plate. The fish module includes a hollow space and is secured to the quad plate. The plant module includes living marine plants and a hollow space, and is secured to the quad plate.

A boat lift is attached to piles driven into the earth or to another object. The boat lift is held in horizontal position relative to piles or the object to which it is attached, but vertical movement of the boat lift relative to the object is permitted. The boat lift is connected to the piles by modular units or cube constructs that have a post extending there through. The post has a blade extending from it. The blades are attached at an angle, according to the application, to pile guides that engage piles. The pile guides vertically traverse the piles, permitting the boat lift to move vertically relative to the object, but fixing the horizontal position of the boat lift.
