Question 2421 Deck General

The correct answer is C) that of the main towing hawser. The reasoning is that the minimum acceptable size for a towing bridle should be such that the safe working load (SWL) of each leg of the bridle is equal to the SWL of the main towing hawser. This ensures that the load is evenly distributed across the bridle, and the bridle can safely handle the same load as the main towing hawser. The other options are incorrect because: A) One-half the SWL of the main towing hawser would not provide sufficient strength for the bridle. B) Three-fourths the SWL of the main towing hawser would also not provide enough strength. D) Twice the SWL of the main towing hawser would be an unnecessarily large and potentially over-engineered bridle.
