Made from high-quality nylon, this 12 inch x 18 inch Rear Commodore officer flag is designed to withstand the demanding conditions of marine environments. Finished with a canvas header and two brass grommets, this dyed flag is easy to fly to signify the presence of a rear commodore, who is typically the third in command to the senior officer of a yacht club or fleet. There are four seams on the outer fly to help prevent fraying.
