Abstract

A depression kite for taking towed bodies down to a certain depth and maintaining them at that depth. Previous kites have been very large and heavy, with very high drag. The kite of the invention comprises a hull plate (1), a deflector (2) attached to the hull plate, a keel (3) extending below the hull plate to which is attached a stabilising fin (4) and a stabilising fin (5) or fins (8a) and (8b) which have a variable position tail plane (9), is attached to the upper surface of the hull plate. This kite allows high towing speeds whilst being light weight and possessing low drag and may be used to maintain towed cables at a predetermined depht.
