correctly? Is my trawl spread optimally? Are my trawl wires marked Trawlmaster is a wireless trawl monitoring system that provides complete trawl geometry. This is one of the most well proven and complete systems available with more than 700 systems Trawlers world over have ex- perienced significant fuel savings coupled with increased catches. Knowing the trawl's geometry allows you to keep the trawl optimal during every tow. Trawl wire lengths provide you with confidence that the trawl doors are in line. In cross current, an adjustment is provided to align the doors. Door spread sensors by speed. This is a well proven method to increase catches in heavy current. Upgrades can be made to these basic door sensors, such as door angle, temperature and depth. Back ture can be provided using headline, bottom contact, wingend and catch sensors. A system consists of ship- board equipment (command unit, computer and hydrophone] that communicate wirelessly dynamic 3D graphic of your trawl is presented that instantly gives an accurate trawl picture.

TRAWL WIRE LENGTHS Doorspread is the distance between the doors on a single trawl. On a twin rig and double rig, the spread on EACH net is given. On triple and quad gear, three and four • Major fuel savings are achieved with doorspread as you can adjust the speed of the vessel to keep the optimal spread. For example, towing just □. 1 knots too fast into a current can overspread the gear by 1 □ meters. • Indicates when your doors have crossed • Detects when your door has fallen or is stuck • Instantly see if you have a rock, pot or other debris in the trawl. • Notus has the only...

Doorspread and trawl wire lengths are standard Trawlmaster sensors. These sensors can be upgraded to include door depth, door angle and temperature. Depth sensors indicate the distance from the surface to • When mid watering, trawl depth allows you to place the trawl at depth of the fish. • When bottom trawling, depth will indicate when the Door angle sensors provide the heel angle (inward/out- ward lean) and pitch angle [upward/downward pitch] optimal spread and optimal fuel consumption shoot too much trawl wire as the door heels over. • Indicates when the doors Temperature sensors...

HEIGHT SENSOR Headline height sensors use an echo sounder to indicate the distance from the headline to the seafloor. An optional footgear clearance sensor can be added for midwater trawling which will also calculate the opening of the net and the footgear clearance. • Allows you to raise and lower the headline depending on species and trawling conditions. • If you see fish at 5 meters off bottom, your trawl should have a 5 meter opening. • Indicates when your trawl is on bottom. • Indicates if currents are raising the trawl off the bottom. This can occur when towing too fast against a...

Catch sensors indicate when the cod-end has a set amount of fish. Multiple sensors can be used to indicate different amounts of fish. For example, one sensor can be set at Vs. the optimal catch to indicate that the trawl is fishing. A second sensor can be used to indicate the optimal amount has been caught and it is time to take back the trawl. • Only take back what you can handle onboard. • Prevents hauling back a trawl that is only half full. • Provides a better indication of exactly where the fish are in the tow. • Has a built in gear location feature should you lose the trawl or just...

Grid sensors indicate angle of the sorting grid. • A necessity on any grid exclusion device. • If your grid is not at the right angle, nothing goes to the cod-end. • Indicates if your grid is blocked. • Estimate fish volume in the codend, as the grid angle tends to change with volume. • Instantly see if the grid is incorrectly rigged.
