Abstract
A trenching implement (41) suitable for towing on the sea bed to make a trench for a submarine cable or pipeline (54) comprises a body (44) attached to which is a soil cutting member (46) which makes a soil surface in the direction of travel of the implement, a landside (45) engaging the soil surface and a towing means (56) connected so that, when the direction of travel is different from the line of the towing force (56), the line of the towing force (56), projected if necessary, passes through a point (50) in the region of the landside (45) with the result that the landside (45) resists the sideways component of the towing force (56). This reduces the risk of damage to the cable or pipeline (54).
