Changing the Number of Trawls

You need to remove specific clumps when reducing the number of trawls in water.

To have correct door spread values displayed on Scala2, you need to be careful when you reduce the number of trawls. Door sensors are configured to operate on specific locations on doors and clumps. If the composition of the trawl gear does not correspond to the configuration of the sensors, spread data will not be displayed.

Triple trawl

Distances sent by Master on port door

Distance sent by inner port clump

Distance sent by inner starboard clump

  • Triple trawl:

  • Triple to twin: keep the inner starboard clump in water.

  • Triple to single: only keep the starboard and port trawl doors in water.

Quadruple trawl

Distances sent by Master on port door

Distance sent by inner port clump

Distance sent by center clump

Distance sent by the inner starboard clump

  • Quadruple trawl:

  • Quadruple to triple: keep the center and inner starboard clump in water.

  • Quadruple to twin: keep the inner starboard clump in water.

  • Quadruple to single: only keep the port and starboard doors in water.

Distance sent by the starboard clump

  • Penta trawl:
