All vessels with fixed toilets that are operated on the
waterwa

g
n coun-
tries are required to be equipped with an operable Marine
S

(

)
. The Marine Sanitation S

.
Note: Overboard discharge capabilities must remain inoperative
while within the 3 mile limit. This is accomplished by closing the
macerator discharge through hull valve. Refer to the Mechanical
Arrangement illustration in the Boating Safety Section or the
