The placard also must note that State and local
regulations may further restrict the disposal of
garbage.
Operators shall display one or more placards in a
prominent location and in sufficient numbers so they
can be observed and read by crew and passengers.
These locations might include embarkation points,
food service areas, galleys, garbage handling spaces
and common deck spaces frequented by crew and
passengers. We recommend that these placards may
be purchased from local marinas, boat dealerships
and marine equipment suppliers. A special placard
is available for boats operating on the Great Lakes.
NOTICE
IMPORTANT: It is illegal to discharge
waste from your marine sanitary device
(toilet) into the water in most areas. It is
your responsibility to be aware of and
adhere to all local laws concerning waste
discharge. Consult with the Coast Guard,
local marina or your dealer for additional
information.
NOTICE
NOTE: Some states and localities have
legal limits on speed, noise and trailer
specifications. It is your responsibility to
be aware of these laws and limits and to
insure that your boat (and trailer) comply.
