USCG Exam Practice · Line handling and mooring
A towing vessel operator purchases a used wire towline from another vessel owner with the intent to use it as a working towline. Under 33 CFR §164.74(a)(3)(ii), what record-keeping requirement applies specifically to this situation?
- AThe operator must keep on board or in company files a record of the towline's original manufacturer's breaking strength only
- BThe operator must conduct a monthly visual inspection and log the results before the first deployment
- CThe operator must keep on board or in company files a record of a retest of the towline's minimum breaking strength determined by a class society or an approved tensile test✓ correct
- DThe operator must obtain written approval from the cognizant OCMI before placing the towline in service
Why C is correct
33 CFR §164.74(a)(3)(ii) specifically addresses towlines purchased from another owner with the intent to use as a towline: a record of each retest of minimum breaking strength, as determined by an authorized class society or an approved tensile test (API Spec 9A, ASTM D 4268, or Cordage Institute CIA 3), must be kept on board or in company files. Relying solely on the original manufacturer's record is insufficient in this circumstance.
