Just in case you want further confusion on lights for non-power boats, look at the rules themselves:
http://www.gencourt.state.nh.us/rules/saf-c400.html
In section Saf-C 403.17 it shows drawings of running lights and the row boat, canoe and small sailboat all show a man holding a lantern. The drawings are tiny but undeniable.
Also, in Coast Guard controlled waters a non-powered boat may exhibit the same red and green lights required by sailboats.
