A blu water lift system for personal watercraft docking systems to raise and lower a personal watercraft into water and retain the personal watercraft for transport. The blu water lift system may be removably attached to boat and a remote activator can be used to manipulate a watercraft between an in-transport condition and a non-transport condition. The blu water lift system may include a carriage structure with a hull-resting plate, at least one carriage rail and at least one pivot mounting arm with at least one bracket assembly, attachment means, and electrically-operated actuator. The blu water lift assembly may be used to removably attach a frame and a carriage structure to a watercraft, operating the at least one pivot mounting arm and operating a loading ramp. Blu water lift systems may be made of corrosion-resistant materials to promote longevity in water-environments.

A navigational system and method for guiding a boat onto a trailer, which comprises at least one marker mounted on the trailer; a camera located on the boat to assist the system with determining a longitudinal axis of the boat, and generating images of at least a front area of the boat and the at least one marker; an image processing unit for 1) receiving and processing the images to determine the at least one marker, 2) estimating the longitudinal axis of the trailer, 3) generating a desired boat trajectory for aligning the longitudinal axis of the boat with the longitudinal axis of the trailer; and 4) periodically generating guidance output commands to the user to assist the user with following the desired boat trajectory and facilitate loading of the boat on the trailer; and an image display for sequentially displaying the generated images of the camera to a user.

An illuminated guide pole for a watercraft-supporting structure includes an elongate LED light source enclosed within a waterproof housing mounted to the supporting structure. The housing includes a transparent pipe for surrounding the LED light source. The light source is electrically connected to a source of power and may include an LED whip light device.

A watercraft lift with rearward and forward lateral beams, left and right side longitudinal side beams, a pair of left side lifting arms, a pair of right side lifting arms supporting at their upper ends left and right side watercraft supports, and left and right side actuators pivotally attached to the left and right side rearward lifting arms. In one embodiment the left side rearward lifting arm and the left side actuator rotate about their pivotal attachments to the longitundinal left side beam in a left side plane, and the right side rearward lifting arm and the right side actuator rotate about their pivotal attachments to the longitundinal right side beam in a right side plane.

The invention relates to a system (1, 2) (1, 4) for handling marine (3) or underwater (5) drones, the system (1, 2) (1, 4) comprising a drone interface module (2, 4) and a floating pontoon (1) with two hulls (11) and an arch (10), the pontoon (1) is catamaran-shaped and delimits a downflooded reception space (17), the arch (10) comprises at least one device (12) for attachment to a winch cable, the pontoon (1) comprises devices (13) for detachable attachment to a drone interface module (2, 4) detachably and interchangeably installed in the receiving space (17), the drone interface modules (2, 4) forming an at least partially flooded docking area (23, 42) for the drone (3, 5), the drone interface modules (2, 4) have a lower portion (22, 43) configured to rest stably on a flat surface after the drone interface module (2, 4) has been removed from the pontoon (1).

Vessel transfer systems are provide herein. The systems include bogies, including a pivoting bogie and a rack and pinion bogie, as well as associated cradles, carriages, and power and control units. The pivoting bogie includes a first side frame, a second side frame, at least one wheel coupled with each of the first and second side frames, and a lift member coupled with each of the first and second side frames. The lift member is pivotably coupled to the first side frame. The rack and pinion bogie includes a frame and pinion gears coupled with the frame. The pinion gears can be selectively coupled with a gear rack, such as at a shipyard. Also provided herein are methods of use of one or both of the bogies and associated equipment, such as for moving vessels within a shipyard.
