Introduction

OPTIMUM FISHING EFFICIENCY WITH AUTOMATIC WINCH CONTROL

 

FISHING PROTECTION

  • Important reduction of trawl damage, time saver and less repair costs.
  • In case of a fastener, a warp-overload is anticipated through automatic shooting of the wires.
  • Propellor pitch reduction if a fastener persists.
  • The effect of fasteners is reduced drastically, especially on difficult grounds.

 

 

MAXIMUM NETOPENING

  • Maximum catch obtained under all working conditions through equal tension control in both wires and consequent length difference.
  • Twin trawl with center wire control
  • Applications:
  • with transverse winds and currents
  • on inclined sea bottoms
  • with adverse weather conditions

 

FAST TURNING

  • E.g: A 2,000HP vessel - 800m warp out. Turn time 180°: 5 min - length difference: +/-80m.
  • Fishing time gain, through fast turning with the ship up to 180°. Without haul-in of the fishing gear.
  • Applications:
  • Target fishing
  • Fishing following curved or parallel tracks

 

SHOOTING-HAULING

  • Time saving through synchronized pay-out and haul-in of the warps towards preset lengths at optimal speed.
  • Labour saving: no more remarking the warps and mark counting.
