Question 2347 Deck General

The correct answer is D) the downward curvature of the hawser. The catenary is the curve formed by a flexible rope or cable suspended between two points. In the context of a towline, the catenary refers to the downward curvature of the hawser (tow cable) as it hangs between the towing vessel and the vessel being towed. This curvature helps to distribute the tension and weight of the towline evenly, which is important for maintaining control and stability during the towing operation. The other answer choices are incorrect because they do not accurately describe the meaning of the term "catenary" in relation to a towline. A short bridle (A), holding the towline amidships (B), and a pelican hook (C) are all related to the towing setup, but they do not specifically refer to the catenary curve of the hawser.
