This class includes structure and attachments peculiar to mooring buoys, marker buoys, container buoys and other buoys; structure and attachment peculiar to rafts, and from analogy, to rafting and guiding of floating logs and similar material; water rescue apparatus; and other aquatic devices.
Water rescue apparatus include devices maneuvered on or over the water surface by one person in order to rescue another person, passenger enclosing devices which are not buoys, rafts or boats and garment or other type of buoyant members, commonly known as personal flotation devices which support a user in the water.
Aquatic devices include swimming aids to cause faster or farther propulsion through the water by the user"s own swimming strokes, buoyant or nonbuoyant devices which support a user and which are caused by external means to roll, skim, glide over or through the water, buoyant underwater viewing devices, and other miscellaneous buoyant support devices.
Lines with other classes and within this class
See Class 440, Marine Propulsion, for buoys or other aquatic devices comprising a motor propulsion means, or animal or human powered propulsion means other than swimming aids as defined in Class 441, subclass 55.
Lifeboats including those which enclose the passenger are classifiable in Class 114, Ships.
A buoyant device made to simulate an animal, fish, fowl, etc., or any part thereof, where such simulation is claimed, is proper for Class 472. However, where such simulation is disclosed but not claimed, classification of the buoyant device is proper for Class 441. See the (2) Note under subclass 129 of Class 441 for a statement of this line.
Class 441, subclass 65 takes all the skimming devices (skis, sleds, toboggans, etc.) which by claim or by disclosure may be used on water, even though also useable on snow or ice. Class 280, Land Vehicles, takes those skimming devices which are useable only on snow or ice.
