Shipwreck Iberia
Iberia struck by Umbria

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:

A fine diagram of a wire-drag operation. The wire is towed between two tugboats, suspended by buoys at a predisposed depth. When the cable snags on an obstruction and draws into a V, the buoys point to its location.

Wire dragging is an operation used to locate and/or reduce the navigational hazard of a sunken wreck, rock, or other obstruction.


LOST AT SEA:
A treatise on the management and ownership
of shipwrecks and shipwreck artifacts

by Michael C. Barnette

shipwreck Lillian

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.


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:


Alpha-Numeric Signal Flags

In this modern age of radio, these signal flags are a quaint anachronism that is no longer used, although they were once very important in ship-to-shore and ship-to-ship communications. Each flag stands for both a letter value and a shorthand message. The letters are expressed here in the modern international phonetic alphabet, in which A-B-C would be spoken Alpha-Bravo-Charlie (see below).

Note: George Hoffman passed away January 14, 1997, about a year after this article was written. His death is a great loss to the diving community and he will be missed by us all.


Shipwreck Rickseckers
Type:
shipwreck, steamer
Depth:
66 ft

This is the remains of an unidentified vessel which we located in August of 1986. She appears to be an old paddlewheel steamship, but this is only speculation and has yet to be confirmed. The only artifact I've found on this little wreck was a perfume bottle with the name "Rickseckers Perfume" on it, hence the name, Rickseckers.
