Port & Starboard
port - the left side of a ship, when facing forward
starboard - the right side of a ship, when facing forward

The starboard side of a vessel ( or an airplane ) carries a green running light, and the port side carries a red running light. The best way to remember all this is: port, left and red are all short words, while starboard, right, and green are all long(er) words.

knife, the most tangible clue to the
identity of New Jersey's mystery U-boat.
In 1991, while checking out an obscure site known for hanging up fishing lines, I dropped down the anchor line only to find a virgin German U-boat. A wreck diver's fantasy of discovering a new shipwreck somehow had become a reality, and it was every bit as good as could be imagined. While reveling in the experience, I wondered if I would have enough skill and luck to ever make it happen again. Several discoveries later, the challenge is still irresistible.

Finding a Shipwreck
by Capt. Steve Nagiewicz

Of course, finding a shipwreck is a necessary prerequisite for finding artifacts. Many wreck locations are well known. Others are secrets, and many wrecks have yet to be discovered. While you can recover artifacts from almost any shipwreck, it is these "virgin" wrecks that are often the best producers of prize items like portholes, deadeyes, and china. But how do you find a wreck like this? Research is the most productive method. This will require visiting local libraries, historical societies, nautical museums, and many other institutions. It means lots of reading and digging for information. Be prepared to spend some time searching for clues that aren't willing to be found.

Side-scan sonar is a modern method of underwater imaging that can produce remarkably detailed and realistic views of shipwrecks and other bottom features using sound rather than light.

Marine distance measurements are expressed in terms of nautical miles. A nautical mile is significantly different from a common or statute mile. The conversion is 1 nautical mile = 1.151 statute miles, or approximately 6076 ft ( vs. 5280 ft for a statute mile. )
Why such a confounded thing as this? Here's why:

How do two ships in the wide ocean collide? It seems unlikely, and yet it happens all the time. Often, the ocean is not all that wide. Many collisions occur in shipping lanes and port approaches, where ships are brought together in close proximity. Here are some videos of actual collisions between ships:
