pump that sucks sea water through a intake seacock equipped with cut-
off valve and filter and delivers it to the watermaker for the production
of fresh water. The intake seacock and the filter are the same delivering
the firefighting system. The brine left over after the desalination process
is drained overboard.

parts (like engines, generator, etc.), of the exhausts systems and to
prevent endangering the yacht safety.
