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.

A system and method for managing information related to marine activities and selectively sharing such information is provided. The system is designed to collect environmental data and create buoy profiles that may be analyzed by users to scout environmental conditions that may be conducive to catching fish in certain geolocations. Buoy profiles are updated in real time by fisherman using the system. The system is also designed to collect information pertaining to a catch and create an activity profile that may be analyzed by users to scout optimal geolocations in which to catch fish. A user's activity profiles may be shared with other users or kept private depending on permission levels within the system. Additionally, the system is designed to alert users of dangerous weather conditions and optimal fishing geolocations based on the buoy profiles and environmental states created by the system.

Apparatus and associated methods relate to a self-contained ocean data and acquisition module (SCODAM) configured to mount to a floating body and having a sensor array, geospatial locating engine, wave measurement engine, communication engine to transmit collected data to a remote device, an energy conversion module adapted to convert ambient energy inputs into electrical energy, and an energy storage module configured to receive the converted electrical energy and to supply operating power to the SCODAM. In an illustrative example, the SCODAM may be configured to generate a transfer function based on motion characterization data obtained in a training mode corresponding to motion of the floating body in response to perturbation in a predetermined sequence and to apply the transfer function data obtained by the wave measurement engine to determine wave motion. Various embodiments may advantageously facilitate use of an existing floating body as an ocean data acquisition system (ODAS).

Provided is a water track marker (1) for marking a sports track, such as a water ski track, on a water surface (20). The water track marker comprises at least a first marker ejector (11) configured to eject marker projectiles (2) towards the water for creating an instant marking (3) on the water surface (20) upon impact with the water surface (20). Provided is also a method for marking a sports track and a towing boat comprising said water track marker.
