A new otter board design from Danish company Thyborøn Trawldoor has been developed specifically for the prawn trawling industry.
Test results showing a 10-20% fuel efficiency saving over the Bison board. The new board “THYson” has been tested/evaluated in both Danish and Australian flume tanks. It has had limited use (1-2 months) on NZ scampi gear and Shark Bay, WA gear with very promising results so far.
The “THYson” has very good shooting away performance, good stability and is compact and robust.
John Wakeford is travelling with the otter board among prawn fisheries.
