I suspect you are referring to one of the Spar Bouy's used for monitoring weather conditions at sea as there are several along the course you describe such as NDBC 41008 at about 31.402N 80.871W. (See National Data Buoy Center). These are listed in the Coast Pilots referred to by David and are likely on the most recent large scale charts as well. Oil Towers and NUI's are not listed in LNM's but are listed in the Coast Pilots. As they are usually fixed structures, they will appear on one's charts the only question being whether their lights are functional. I have seen many and only in a few cases were the light's on (abandoned) structures not working.
FWIW...
