Hull unit
General
The sonar hull unit must be under continuous watch as a part of
the vessel’s machinery. As the hull unit may be exposed to
severe strain because of pitching and vibrations, it must be
inspected regulary for loose parts.
In addition to lubrication, check for signs of corrosion. If
required, clean the corroded areas and paint over with a high
quality protective paint.
