Abstract:
A method for reducing strum in a tow cable extending from a marine vessel, said cable having an adjustable length and there being in said cable at least one longitudinal wave and at least one transverse wave wherein the cable has a proximate end on the marine vessel and an opposed distal end where at said proximate end the cable has a rigid boundary and at the distal end the cable has a free boundary; and the cable is connected to a means for varying the cable length at the proximate end of the cable; and there is a towed component at the distal end of the cable and an acceleration measuring means capable of providing a reading is positioned adjacent the distal end of the cable; and the length of cable being adjusted based upon the reading from said acceleration measuring means such that the number of longitudinal waves is about an integral number.
