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:

LOST AT SEA:
A treatise on the management and ownership
of shipwrecks and shipwreck artifacts
by Michael C. Barnette
Somewhere out on the ocean, a ship is in distress. Tossed about by churning seas and brutal winds, the vessel struggles to stay afloat. Her crew puts forth a valiant effort while passengers, many incapacitated by waves of nausea spawned by the ever-moving deck underneath their feet, huddle together in fear. The hull is slowly breached, and seawater steadily invades the ship. As the blitzkrieg of flooding water rises to extinguish the boiler fires, the vessel loses all power. Cast in darkness and overwhelmed by the noise of the howling wind and crashing surf, the sea tears off sections of the crippled ship, carrying away numerous unfortunate souls. The end is near.

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.

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:

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.
