For your trawl safety,
trust the leaders!
MARPORT is one of the world leaders in
commercial fishing net positioning sensors. MARPORT was founded in Iceland in
1996 with the goal of developing acoustic monitoring systems for deep-sea
commercial fishing fleets. Today his engineering team manufactures a wide
variety of subsea sensor products.
TZ Professional is now compatible with MARPORT trawl positioning sensors.

The Trawl positioning module allows for an easy display of information, for
example, the distance between the selected door and your boat, the depth and the
distance between your boat and the bottom. The color coding used for the doors
(red for port and green for starboard) allows you to quickly see your trawl
doors, directly on your navigation charts.
TIMEZERO also offers the ability to display your trawl in 3D through the
dedicated 3D Cube workspace. In fact, the vertical distance between your trawl
and the bottom is accounted for! In addition to seeing the precise position of
your fishing net, you can visualize the environment surrounding your trawl. This
lets you know very quickly if your net is approaching a shipwreck, a rock or the
bottom of the sea. This is probably the best available security for your fishing
The position of your trawl doors can be recorded automatically in the
software thanks to the new Logbook database. You can now replay previous
positions of your boat and trawl in the Planning workspace in TZ Professional.
This unique function was developed to help you visualize the position of your
net in function of the position of your boat, all throughout your navigation.
TIMEZERO is capable of displaying COG and SOG vectors of your trawl doors,
allowing you to visualize the movement of your net as you move. The movement of
your trawl doors is highlighted by a red trace (port) and a green trace
(starboard). This display allows you to know where and how your fishing gear is
Combined with a compatible multi-beam sounder (WASSP
G3 or FURUNO DFF3D), TZ Professional will literally display the fish entering
the trawl. The Trawl Positioning Module comes with a unique 2D/3D Fish Targets
