Class 441
BUOYS, RAFTS, AND AQUATIC DEVICES
Class Definition:
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.
