John S Dempster Jr. is sister to Shearwater and Reedville, see those vessels for details, links in the sidebar. All three vessels were originally small Army transports, converted to Menhaden fishing by Omega Protein company. FS-355 was USCG-manned, and retained by USA as PVT Carl V. Sheridan (see below) until sold in 1972.
The aging Shearwater and Reedville were retired when Omega got two new modern vessels in 2017, but Dempster was kept as a reserve. Finally, almost 80 years old, the Dempster was sent to her reward as well. Another sister, Tangier Island, was reefed off Georgia in 2020. As of 2023, one old sister remains - Smuggler's Point, FS-400, launched in 1944!

Environmental group Clean Ocean Action lobbied aggressively and almost successfully to prevent the use of these subway cars as artificial reefs in New Jersey, resulting in most of the cars going to other states.
All manner of concrete, steel, and stone rubble from dredging, demolition projects, and other construction is used as artificial reef materials. This material is generally available at very low cost or free from construction companies who are more than happy to get rid of it. Transportation costs determine where this material is used by the Reef Program.
