I found the following article on the Internet.....perhaps this will give you the informaiton you are looking for? I know most of you have heard about the missing fisherman out of Atlantic Beach on Thursday that has not been found. The below brings to mind several items we should all know, but I feel we need reminding from time to time. “Coast Guard officials said Michael Dodick, 67, left his summer home in Indian Beach around 5:30 a.m. Thursday for a day of fishing, departing from Anchorage Marine in Atlantic Beach. Reports indicate that he was headed to Big Rock, about 42 miles offshore, and did not return at 4 p.m. as scheduled the Coast Guard was notified.” “On Friday 28-foot Grady White fishing boat belonging to a missing fisherman was found with the engines idling near shore at Camp Lejeune around 12:50 p.m.” “Authorities said Mr. Dodick had a cell phone and a VHF radio on board his vessel, but neither would be very effective beyond a range of 20 nautical miles.” “According to officials, boats that venture offshore and move beyond the normal communication range experience static and breaks in communication from cell phones and VHF radios and recommend boaters going beyond 20 miles to consider the use of a single side band high frequency radio that can transmit up to 200 miles. These radios are capable of worldwide communication, making them practical for even small boats.”
