The correct answer is B) have equal legs of sufficient length. An ocean towing bridle should have equal legs of sufficient length to distribute the load evenly and provide stability during the tow. This helps prevent uneven tension on the towing vessel and towed object, which could lead to equipment failure or loss of control. The equal leg length also allows the bridle to form a symmetrical configuration for optimal load distribution. The other answer choices are incorrect. A large angle between the legs (A) could create an unstable configuration. Forming the bridle on a bight of cable through a ring (C) is not the preferred method, as it can create a weak point in the connection. Using chain (D) is generally not recommended for ocean towing due to the risk of failure under the high loads and dynamic conditions.
