Marine Sanitation System
Waste in the holding tank can form methane, an explosive gas. Keep
vent open and clear of obstructions. Keep fire and flame away when
maintaining the system.
It is illegal to dump plastic trash anywhere in the ocean or navigable
waters of the United States, including the Great Lakes. The discharge
of other types of garbage is permitted outside of specific distance
offshore as determined by the nature of that garbage.
All recreational boats with installed toilet facilities must have an
operable Marine Sanitation Device (MSD) aboard. Vessels 65 feet
and under may use a Type I, II, or III MSD. All installed MSD's must
be Coast Guard certified. The Holding Tank installed in the Chris-
Craft is certified by definition under the regulations and is not specifically
labeled. Do not flush foreign objects down the MSD. Damage
to the system may result.
The Catalina models use a porta potti system as the standard Marine Sanitation System. A Tecma system is
available as an option on the Catalina 26 and 29 models. The Marine Toilet Owner’s Manual that comes in
your documentation package addresses the use, maintenance, and troubleshooting of the waste system. It is
your responsibility to become familiar with its contents.
The optional Tecma units utilizes a grinding system that grinds all waste before it enters the pump. This
system virtually eliminates clogging while consuming very little water. To use, press the “Add Water” button
(Figure 3-17) to send a specific quantity of water into the bowl. Press the “Flush” button to begin the
automatic flushing cycle. This leaves the water closet clean and dry. The cycle is completely automatic and
works on a 12/24 VDC electrical system.
