In many cases, the neg is connected to the engine block and many engines are connected to (via the shaft) to the water outside. You do not need other ground.

BUT this all depends on the boat - some are made of metals and have isolated engine blocks, others have soft couplings and thus no connection from the engine to the water, etc.

Boats that have heavy gauge electronics (e.g. HF radios) have special ground plates fitted to the outside of the hull.

Lightning strike ground (if present) is often the keel (ballast) itself. Note some boats have encapsulated ballasts ...
