The apparatus is towed via a towing yoke (49) attached to a towing cable. The slats (50,54) have upright front portions (51) which define flow passages (53) therebetween. The trailing portions (52) are upwardly inclined to generate a downforce to urge the apparatus to the ocean floor. On the mid-water boards (47), the lower slats (54) have hinged trailing portions (55) which are adjustable to enable the mid-water boards (47) to be towed down to, and maintained at, a desired depth.
