Good to haul and shoot Lighter to tow Effective spreading force Perform well in a turn, are stable throughout and keep the gear square Ekkó doors immediately lift back to the towing position as soon as the trawl is free of a fastener
Low-drag
Very low angle of attack ensures low towing resistance That means reduced loads on engine and winches, resulting in lower fuel consumption
Strong and durable
Built from exceptionally durable steel with ideal combination of flexibility and high strength
Environmentally friendly
Lighter to tow, which translates into lower fuel consumption The doors are easily adjusted to fly clear of the seabed, minimising ground contact and leaving seabed benthos untouched Ekkó doors are made from 100% recyclable steel
Innovative three-stage airlock system
An innovative aspect of the Ekkó doors is the set of airlocks in the upper section of each door. This provides the opportunity to adjust the amount of air retained in the upper chamber. These airlocks can be easily activated and adjusted by simply screwing a bolt into the top plates of each door, or deactivated by removing a bolt to allow water to fill the required chamber. This allows the doors to be easily adjusted to fly effectively above the seabed.
Adjustable weight
The lower door sections can be opened if required, so that the weight can be adjusted by adding or removing lengths of chain as required.
