Updated CG Work Instruction Approves Shoulder-Fired Line-Throwing Appliances

The United States Coast Guard’s Office of Commercial Vessel Compliance has released an update to Work Instruction CG CVC-WI-010(3), which provides guidance to officers in charge of marine inspection (OCMIs) on special consideration for inspected towing vessels.

The updated Work Instruction stipulates that shoulder gun-type line-throwing appliances approved under 46 CFR §160.031 may be used in lieu of impulse projected rocket-type line-throwing appliances approved under 46 CFR §160.040, which had previously been the only acceptable line-throwing appliances under Part 141 of Subchapter M.

The American Waterways Operators, which has advocated for this acceptance with the support of coastal members, noted the change of guidance in a recent newsletter to members.

The updated Work Instruction also includes new guidance on the use of electronic visual distress signaling devices (eVDSDs), permitting non-SOLAS vessels on Lakes, Bays and Sounds and Rivers routes, as well as short-duration Great Lakes or Coastwise routes, to carry one eVDSD in lieu of six day and night flares.
