In order to maximize the performance and the catch efficiency,
the trawl and the warps must be adjusted properly. This is
essential to ensure a square trawl and minimum skew. This is
also important for danish seines, as the ropes must have identical
length.
Any disturbance to the trawl movements may have a negative
effect on the catch. This is particularly important on a bottom
trawl. A skewed bottom trawl will result in unstable bottom
contact, and create escape routes for fish below the gear and
through the side panels. On pelagic trawls and danish seines a
