Interesting! I was a quartermaster in the Navy back in the late 60's. Our electronic navigation consisted of Loran C. In the Caribbean Sea I still shot stars and sunlines and local apparent noon, dead rekoning when the weather was bad. Was on the USS Lawrence DDG 4, and the Spiegel Grove LSD 32. Navigation has changed some since then.I knew Ted was a weeny!
I am considered to be the leading expert in electronic navigation for the US Navy. I install, repair and mostly train US Navy sailors how to navigate ships of every size and flavor using computers, like Google maps for a ship, all designed to drive the ship without touching the wheel. I'm a retired Submarine sailor of 24 years. Sell aftermarket chainsaw parts as most know me by. I flip saws on the side as an excuse to drink beer and I help my wife run one of the largest interior design businesses in the greater tidewater area of Virginia.
I can't remember what I ate for lunch most days!
