DEFINITION

Classification: 414/138.7

Marine vessel to/from lighter to/from shore:

(under subclass 137.9) Apparatus including a buoyant vehicle intended to load or unload another buoyant vehicle and transport the material to/from the terra firma surrounding or beneath the water in or on which the buoyant vehicle floats.

(1) Note. The term "lighter" is somewhat confused in the art, and is considered to refer to any vessel intended to support such transported material which includes a small boat on which a material handling device is carried, a floating structure that is in effect an extension of a dock, or a large vessel having the purpose of transporting material to or from another vessel at a single portage. The lighter may include a hold for temporary storage of material. Such a vessel may also be referred to as a "tender" or as an "oiler".

(2) Note. The term "shore" is intended to include the land surrounding the water as well as the sea bottom.
