Definition: Ship (Boat)
Seagoing self-propelled surface-displacement vessel.
Note: Catamarans (High Speed Craft) are included. Hydrofoil, air cushion vehicles (hovercraft), submersibles and submarines are excluded. A seagoing ship actually goes to sea, that is, outside the boundary within which inland waterway technical safety regulations apply, and outside which the ship's operators must satisfy the seagoing regulations.
