| Definition | An open pair of 50 cm diameter circular net hoops were mounted on each end of a 150 cm wide cross-strut which was attached to a towing cable. Nets were attached to the bottom of the hoops and their cod-ends were attached to a spreader bar which was also attached to the wire. The nets were lowered to a maximum depth to haul and then during the haul back to the surface, a messenger was used to close the nets either by releasing the hoops so that they turned 90 degrees or by releasing the nets which fell back and were pursed by throttling lines attached to the cross-strut. A non-opening/closing variant of this net is known as the CalVET net [Wiebe and Benfield 2003 Plate 10 A]. | ||
