System and method of controlling force developed by a paravane system

A method comprising:

• towing a paravane system through water, the towing by way of a bridle comprising a plurality of fixed-length forward lines coupled to a respective plurality of forward tow points, and a plurality of fixed-length aft lines coupled to a respective plurality of aft tow points;
• and while towing the paravane system through the water
• changing lateral force supplied by the paravane by changing a location of a first forward tow point and a corresponding first aft tow point relative to a first frame, at least one of the tow points defined at least in part by a first trolley, and wherein a distance between the first forward tow point and the corresponding first aft tow point remains substantially unchanged.
