USCG Exam PracticeMarlinespike seamanship — knots, splices, line care
An AB is ordered to stopper off a mooring line that is surging on the bitts so the line can be transferred to a cleat. Which knot is specifically suited to take a strain along another taut line for this purpose, and why is a clove hitch alone insufficient?
- A. A bowline is used because it forms a fixed eye; a clove hitch is insufficient because it cannot be tied on a bight
- ✓ A rolling hitch is used because it takes a strain along a spar or taut line; a clove hitch can work loose under a varying or axial pullCorrect
- C. A sheet bend is used because it joins two lines of unequal size; a clove hitch jams under heavy load and cannot be released
- D. Two half hitches are used because they make a line fast to a post; a clove hitch lacks a locking turn
Why B is correct
NAVEDTRA 14067 §3-2 states the rolling hitch takes a strain along a spar or onto another taut line and is used to stopper off a line under tension. The same source notes the clove hitch can work loose under a varying pull, making it unreliable for an axial load along a taut line.
