USCG Exam Practice · Line handling and mooring
Under 33 CFR §164.74(b)(6), a wire towline winch is required on a towing vessel EXCEPT in which of the following situations?
- AWhen the towline's minimum breaking strength exceeds the vessel's bollard pull
- BWhen the vessel is towing in ice on Western Rivers or is using a synthetic or natural fiber towline✓ correct
- CWhen the towline has a poured socket termination rather than a thimble splice
- DWhen the tow exceeds the towing vessel's length by more than three times
Why B is correct
33 CFR §164.74(b)(6) exempts vessels towing in ice on Western Rivers and vessels using a towline of synthetic or natural fiber from the requirement to fit a winch that evenly spools and tightly winds the towline. All other wire-towline towing operations require such a winch.
