Vistar 172
The Vistar 172 was designed as a lower cost device to aid navigation of
large yachts, work boats, in fact anyone who may wish to navigate
safely at night.
The 172 was not designed to meet either the IMO or the Hong Kong
specifications but is intended for use where IMO Regulations are not
mandatory.
The system is designed to aid
the helmsman in navigating in congested waters or moorings. The 172 can
be invaluable in detecting objects in the water ahead of
the craft such as debris, unlit craft or swimmers.
The basic system consists of a fixedVigilant 18
mm image intensified camera with a wide field of view (30°) mounted to
give a clear and unobstructed view forward.
The CRT display is mounted inside the bridge or cabin. The images
presented on the display give the helmsman a clear picture of
what lies ahead, showing objects that may remain invisible to
radar.
Many of the features that Vistar have developed for use
on fast ferries are included in the 172. An electronic visor can be
lowered from the top of the screen to eliminate glare from harbour
lights. Range markers enable estimates of the target range to be made.
A washer and wiper ensures the camera window kept clear.
