On an OSV, how many ring buoys are required to have a buoyant line attached?
Official USCG Answer & Rule Citation
Correct Answer: Option B — One ring life buoy on each side of the OSV
46 CFR 133.70 requires that at least one ring life buoy on each side of an OSV be equipped with a buoyant line. This ensures that a rescue device is immediately available for throwing to a person in the water from either side of the vessel during an emergency.
