| roll |
The rhythmic movement of a ship or towbody about its longitudinal axis. When working from a well designed support vessel, roll will not contribute to towfish instability to the same extent as heave in any given sea state. Roll can affect the ability of crews to perform at sea, as well as destabilize unsecured equipment. However, to preserve data quality, many surveys will use a different vessel heading allowing the vessel to roll instead of pitch or heave.
