Abstract: Covers and methods to protect outer surfaces of marine equipment are provided. The covers are manufactured to extend along at least one dimension. The covers may have antifouling properties due to the thread used to manufacture the covers or due to treatment applied to the covers after manufacturing. The covers are removably mounted on one or more pieces of marine survey equipment, without employing fastening mechanisms.

Abstract: A water-fillable fairing configured to be mounted on a cable has a fairing body and an inlet. The fairing body is at least partially made of a flexible material, and is able to hold water at a higher pressure than an average pressure outside the fairing body, while the cable is towed. The inlet, which is located on a front part of the fairing body in the towing direction, is configured to allow water to enter the fairing body when the cable is towed.
