e U.S. Coast Guard requires a method of re suppression on ev-
ery boat operating within U.S. waterways. MasterCra has made
this an optional installation because of the recognition that needs
can vary considerably. In some instances, consumers may want to
purchase a re extinguisher from an aermarket supplier. Master-
Cra also oers a standard, manual re extinguisher that can be
installed at the time of purchase or at any point aer the fact. In
some models, an automatic re suppression system is available for
the motorbox area. is system operates o a sensor, and there
is no need for the boat operator to manually start it. However, as
with any addition to a boat, there is potential for failure. For that
reason, MasterCra recommends that boats be equipped with a
manual re extinguisher unit as well.
MasterCra further recommends that boat owners include a
check of the re suppression and extinguisher units during the
annual maintenance to be sure that they are always ready for
use. Some units may not require annual checks; refer to the sig-
nage and labeling on the individual units for further guidance.
