Question 1601 Deck General

You are correct, the answer is A) the bow spring line. When mooring a vessel starboard side to, bow in, the bow spring line is typically put out first. This is because the bow spring line helps to control the fore-and-aft movement of the vessel as it is being brought alongside the mooring structure. The bow spring line is an essential line that prevents the bow from swinging out and allows the vessel to be securely positioned. The other options are incorrect because the stern line, head line, and after breast line serve different purposes in the mooring process and are not the first line that should be put out in this scenario.
