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.

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.

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 boat anchor monitoring system is disclosed and includes a status indicator and an anchor module that are 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 the 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.

An anchor system including an anchor having a body member and a first arm pivotally coupled to the body member. The first arm is movable between a closed position wherein the first arm is positioned adjacent to the body member and an open position wherein at least part of the first arm is spaced away from the body member. The system further includes a second arm pivotally coupled to the body member and movable between a closed position wherein the second arm is positioned adjacent to the body member and an open position wherein at least part of the second arm is spaced away from the body member. At least one of the first or second arms has a cavity that is exposed when the at least one of the first or second arms is in the open position. The at least one of the first or second arms includes a protrusion extending therefrom.
