An autonomous watercraft race course system using automated buoys, sensors, and a race course application for autonomously setting up, starting, conducting, and scoring a race. The race can be any type of race conducted on or near water. In a preferred embodiment the race is a sailing race, however, it is within the scope of this invention for the race to include races for power boats, personal water craft (i.e., jet ski), waterskiing, wake boarding or surfing and over water aircraft races.

A system and method for tracking marine equipment is provided. Generally, the system and method of the present disclosure are designed to generate indicia corresponding to the inventory level of marine equipment used for a particular marine activity. To facilitate the assignment of indicia reflecting the inventory level of marine equipment used for a marine activity, the system and method of the present disclosure uses a plurality of equipment profiles having a defined lower limit and quantity associated with each piece of marine equipment. The lower limit may be manually input or automatically generated. The quantity may be tracked by the system using equipment transmitters and equipment sensors. In a preferred embodiment, the indicia indicate whether the quantity of a piece of marine equipment has fallen below a certain specified level as defined by the user. Users may purchase new marine equipment from third-party retailers via the user interface.

A floating waterway marker device in the form of a buoy or a waterway navigation mark is provided. The device includes a body and an at least one light source, wherein in the body a number of periodically spaced recesses are circumferentially arranged to a predetermined depth. The waterway marker device further includes a number of optical fibers extending from the at least one light source to each of the recesses and configured to convey light emitted by the at least one light source such that exiting light is directed to an ambient around the periphery of the waterway marker device.

The invention relates to a buoy comprising a buoyant, plastic core component, and a plurality of detachable flotation components that support and surround the core component. The buoy is preferably more than 2.5 metres diameter, but the diameter of the core component is preferably less than or equal to 2.35 metres diameter. This facilitates transport in a single shipping container. A novel tie bar assembly and novel lifting/mooring mounts are also disclosed.
