Crimond Enterprises Nova Trawls are a product of computer aided, three dimensional design techniques. The 4 seam design allows for a variety of mesh sizes in the wings and square to eliminate drag. The trawls are constructed of high grade, heat stretched, Polyethylene netting. The netting is hung on combination wire rope, the Headline is hung on Polyester guard and the Fishing Line is hung with heavy guard netting and then wrapped with braided rope to protect the hanging meshes. The trawl has simple design features, which include short wings, making it an excellent trawl for extremely hard ground. The 4 seam design tends to gibe better vertical openings than the 2 seam design.
Flotation is normally 8 inch heavy duty floats, or kites can be used, the groundgear is normally Rockhopper type, the size of discs depending on the horsepower of the vessel and the grounds to be fished.
The trawl is normally used to fish the following species: Cod, Haddock, Pollack, Hake, Flounder, etc. and is used on medium to hard ground by a variety of vessels with different horsepower.
Before a trawl is constructed Crimond Enterprises requires certain parameters from the customer, which are then generated through a database to determine the trawl size and door size to suit the particular vessel.
As with other Crimond Enterprises trawls scale models are usually tested in a Flume Tank and these results are verified by commercial testing at sea with full scale gear using Electronic Gear Monitoring Systems.
