The present invention relates to a hybrid dynamically installed anchor with a folding shank and a control method to keep the verticality of the hybrid anchor during free fall in the seawater, which can be applied to the field of offshore engineering. The hybrid anchor comprises a folding-shank plate anchor, a ballast shaft, an extension rod, a plurality of rear fins, and a recovery hole from the front to the tail. The folding shank is not only useful in reducing the water and soil resistance during installation, but also beneficial in improving the directional stability of the hybrid anchor during free fall in the seawater. The re-used shaft can significantly increase the penetration depth of the folding-shank plate anchor and reduce the installation cost at the same time. The control method keeping the verticality of the hybrid anchor can improve the success rate during anchor installation.

A support system for outboard marine motors at the transom of a boat includes a support device having a first part that is integral with the transom and a second part that is integral with the outboard motor. The second part is translatable with respect to the first part, so that the second part moves according to an orientation in the distancing or approaching direction of the water line of the boat. A control unit is configured to set the position of the second part with respect to the first part and to generate control signals, so as to move the second part in the direction of immersion of the propeller of the outboard motor.

A collapsible anchor for lightweight watercraft includes a handle member, including a left grip and a right grip, wherein the left grip and right grip are located across a central member from each other; a first tube member, the first tube member attached to the handle member and extending downward in a vertical orientation from the handle member; a second tube member, the second tube member removably attached to the first tube member and extending downward in a vertical orientation from the first tube member; and an auger member, the auger member attached to the second tube member and extending downward in a vertical orientation from the second tube member.

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.

A yoke plate assembly for mooring a floating object in a body of water by a pair mooring lines, includes an assembly plate mechanically coupling to an anchor body, an elongated yoke plate with a center thereof pivotally connected to the assembly plate by an articulation, a first lever arm having a first proximal end connected by a first coupler to a first end of the elongated yoke plate, a second lever arm having a second proximal end connected by a second coupler to a second end of the elongated yoke plate longitudinally opposite the first end. The first lever arm at a first distal end thereof is connectable by a first distal joint to one of the pair of mooring lines, and the second lever arm at a second distal end thereof is connectable by a second distal joint to the other of the pair of mooring lines.

A boat anchor monitoring system is disclosed and includes an anchor module operable to communicate with a base module. The anchor module includes a transmitter operable to transmit a signal containing a data payload on a set schedule. The base module on the boat is operable to determine if the signal strength exceeds, or is equal to a predetermined threshold value, in order to direct a status indicator to either display the anchor in a “Deployed” or “Not Deployed” position. The system may further include a time measurement component or water contact sensor that will direct the indicator to display the anchor in a deployed position if sufficient time has elapsed with no signal or the anchor module has contacted water. The system is also configured to prevent ignition if the anchor is determined to be deployed.

A system and method for deterring theft of a marine vehicles is provided. The system is designed to collect barometric pressure data and analyze it to determine whether there has been a sudden change in elevation that may be indicative of a theft. The system is also designed to collect environmental data pertaining to a marine vehicle's normal environment and compare it to a normal environmental state of the marine vehicle in order to detect changes that may be indicative of a theft. Additionally, the system is designed to monitor equipment of the marine vehicle and alert a user if the equipment has been moved in a way that may be indicative of a theft. When the system determines an event has occurred that may be indicative of a theft, the system may alert the user by triggering an alarm via a computer readable signal.
