A boat with an inner cabin suspended on a rotating shaft inside an outer shell. The outer shell completely encloses the inner cabin. The inner cabin freely rotates on the shaft inside the outer shell to maintain an upright orientation in any sea condition. Optionally, a motor is provided between the inner cabin and outer shell to dampen rotation of the inner cabin.

The present invention discloses an integrated automated driving system for a maritime autonomous surface ship (MASS). The integrated automated driving system for a MASS includes a perception module for perceiving navigational environment of a MASS and obtaining real-time dynamic information of a navigation channel, hydrology, a state of the MASS and traffic environment; a communication system for transmitting data and instructions between the MASS and a shore base as well as between system modules; a data processing module for processing information obtained by the perception module; a decision-making module for identifying a current operating status of the MASS and environment according to data outputted by the data processing module, selecting actions to be taken, and generating operating instructions corresponding to the action; and an execution module for receiving operating instructions sent from the decision-making module and controlling a propeller and a rudder of the MASS through a proportional-integral-derivative (PID) controller.

The invention relates to a system (1) for use with a crane (4) on a surface vessel (3), comprising a crane tool (15) attached or attachable to a hoisting cable (5) of the crane (4) and one or more adaptors (16) attached or attachable to one or more tools (11-14, 25) for carrying out operations or to one or more components (2, 10), the crane tool (15) comprising a connector (17) and at least one of the adaptors (16) comprising a connector-counterpart (18).

The present invention includes systems and methods for a continuous-wave (CW) radar system for detecting, geolocating, identifying, discriminating between, and mapping ferrous and non-ferrous metals in brackish and saltwater environments. The CW radar system generates multiple extremely low frequency (ELF) electromagnetic waves simultaneously and uses said waves to detect, locate, and classify objects of interest. These objects include all types of ferrous and non-ferrous metals, as well as changing material boundary layers (e.g., soil to water, sand to mud, rock to organic materials, water to air, etc.). The CW radar system is operable to detect objects of interest in near real time.

The present disclosure includes recreational watercraft including a drop down boarding point. One example includes a hull, an open platform passenger deck, and a plurality of sides, continuous from the hull. The watercraft includes a panel drop down boarding point, hingedly attached horizontally to the hull, for ingress and egress of persons to the watercraft. The panel drop down boarding point includes a first surface interior to the watercraft when the panel drop down boarding point is closed, a second surface, opposite to the first surface and exterior to the watercraft when the panel drop down boarding point is closed, and an aperture formed between the first surface and the second surface and having an opening in an end surface of the panel drop down boarding point. The aperture is sized and shaped to house a retractable ladder and for the ladder to extend out through the opening.
