A watertight door or window comprising a frame and a leaf mounted on the frame and arranged movably with respect thereto between an open position and closed position, and further comprising: a striker element arranged on the leaf, a locking element arranged on the frame and provided with a hook end designed to engage with the striker element so as to lock the leaf against the frame following closing of the leaf, and a striker actuating mechanism arranged on the leaf and able to be actuated when the leaf is in a closed position and the locking element is engaged with the striker element. The actuating mechanism is provided for releasing the striker element from a closed position, where the striker element is positioned inside a recess in the hook end of the locking element, to an open position, where the striker element is extracted from the recess in the hook end of the locking element. The actuating mechanism can be reset when the leaf is closed again.

A bulwark terrace with integrated door is provided; the bulwark terrace may be a portion of a bulwark on a ship or yacht that is hinged so as to be able to fold outwards and downwards and be flush with the deck after doing so, thereby extending the deck surface. The bulwark terrace may also include a door that may open independently of the bulwark terrace to allow boarding of the yacht or ship through the bulwark without deploying the bulwark terrace.

This disclosure includes apparatuses and methods for directing fluid. Some apparatuses include a frame configured to be coupled to a surface of a structure and a plurality of fins configured to be coupled to the frame, each having a width, a length greater than the width, and a bottom surface, wherein, when the frame is coupled to the surface of the structure and the fins are coupled to the frame, the bottom surface of at least one of the fins is angularly disposed at a non-perpendicular angle relative to the surface of the structure such that the fin redirects fluid that contacts the bottom surface of the fin away from the surface of the structure. In some apparatuses, the frame includes a first end and a second end, wherein the first end is configured to be coupled to the surface of the structure such that the second end is free.

An anti-piracy device for ships comprises a blocking device, such as a metal plate, to block an opening from the exterior to the interior of a ship, such as a window or porthole. The anti-piracy device also includes mounts, which are mounted permanently to the interior wall of the ship, to which the blocking device can be removably fastened, by nuts or the like. This allows the device to be installed when entering dangerous waters, but removed and stored when traversing safe waters.
