Disclosed herein are stackable cages for holding oysters, modular cages for holding oysters, floating platforms for deploying and retrieving oyster cages from a long line, and floats adapted to engage a plurality of oyster long lines and from which one or more oyster cages may depend.

An offshore electrical charging system and process may include a marine vessel. Multiple flywheels may be stored on the marine vessel. An electrical power network or system may be positioned on the marine vessel, and be electrically connected to the flywheels. An electrical connector may be in electrical communication with the electrical power network to enable electrical power from the flywheels to flow via the electrical connector to supply power from the marine vessel. At least one power switch may be disposed on the electrical power network, and be configured to enable electricity to flow between the electrical connector and flywheels. A controller may be configured to control the at least one power switch to enable and disable electrical power to flow between the flywheels and the electrical connector via the electrical power network.
