A method and apparatus for connecting a V2X-enabled terminal to a local vehicle-to-everything (V2X) server is provided. A communication method of a terminal of the present disclosure includes transmitting mobility information of the terminal to a macro vehicle-to-everything (V2X) server performing V2X communication with the terminal, receiving provision information for connection to a local V2X server taking charge of an area predicted as a next-hop area to which the terminal moves from the macro V2X server, and establishing, when the terminal enters the next-hop area, a connection to the local V2X server for V2X communication based on the provision information.

In a small boat emergency stop apparatus having an operator's cockpit and a passenger seat installed spaced apart from the cockpit, there are provided with an operator transmitter wearable by the operator to transmit a radio-wave signal of a predetermined strength, a passenger transmitters wearable by the passenger to transmit a radio-wave signal of the same predetermined strength and a receiver installed at a location closer to the cockpit than the passenger seat to receives the radio-wave signals transmitted by the operator and passenger transmitters successively. It is identified which of the operator and the passenger is a wearer of the transmitter and is then discriminated whether strength of the radio-wave signal transmitted from the identified wearer is smaller than a predetermined value. When it is, it is discriminated that emergency occurred in the wearer and an emergency action of engine stopping or engine speed reducing is performed.

In some embodiments, a monitoring system may include an enclosure defining a void. The enclosure may be configured to be mounted to a floating vessel. The monitoring system may also include a camera system disposed within the void and coupled to the enclosure. The camera system may be configured to transmit a video feed of an anchor chain to at least a first computing device. The first computing device may be configured to analyze the video feed to determine a drag risk score with a computer vision model based at least in part on an angle of the anchor chain. The first computing device may be configured to determine a collision risk score. Other systems and methods are also disclosed.
