... To strengthen this point -- though I know only some of the newspaper accounts of the tragic Tampa Bay accident -- it was reported that a member of the state bridge commission (after several prior accidents) likened protection around the bridge tower dock structures to placing a metal shield over every home in the United States for protection from falling aircraft.

... Conversely, as the channel narrows, the need to mark it well increases. A 2000-foot-wide channel, such as Ambrose leading into New York, is regularly run in poor visibility using radar, without undue apprehension.

... A system that uses a shore station, when receiving signals from two transmitters located fore and aft on the centerline of the vessel, instead of just one transmitter at the center of the ship, will also give the vessel's rate of turn in a bend. Pilots are as interested as anyone in navigational advances for harbor and entrance design.

... Interestingly, if he tells them that be wants 10 degrees right rudder, they put the rudder over 10 degrees right, but the tugboat on the stern starts working slow a bead on the starboard quarter. If he increases the rudder to 20 degrees right rudder, the tugboat on the quarter increases speed to half ahead on the starboard quarter and if he says hard right, the tugboat hooks it up.
