In 1980, the eruption of Mount St. Helens deposited large amounts of sediment in the lower Columbia, temporarily reducing the depth of the shipping channel by 26 feet.
You'd have had to go down into the depths of the ship.
During the crew's final meal before re-entering stasis, Kane begins to choke and convulses in extreme pain as a small alien creature bursts from his chest, killing him, and escapes into the depths of the ship.
The Coast Guard has increased the depth of a ship's hull allowed on the lower Mississippi River to 39 feet from 35 feet.
The Delaware project calls for engineers to increase the depth of the 103-mile-long shipping channel from 40 to 45 feet, which supporters say is necessary to accommodate large container ships and oil tankers.
The captain proceeded in the fjords at very slow speed, barely moving forward, by lowering an anchor from the bow to a depth greater than the hull of the ship.
While Bahias gunners were firing at a kite for anti-aircraft practice, one aimed too low and hit depth charges stored near the stern of the ship, resulting in a massive explosion that incapacitated the ship and sank her within minutes.
At the instigation of one of its members, Samuel Plimsoll, a merchant and shipping reformer, the British Parliament, in the Merchant Shipping Act of 1875, provided for the marking of a load line on the hull of every cargo ship, indicating the maximum depth to which the ship could be safely loaded.
The depth finder is on the port side of the ship, however, and the sandbar to starboard, only a few feet down.
Ramsey concluded that increasing the hull length to 729 feet resulted in a L/D slenderness ratio (the ratio of the length of the ship to the depth of her structure) that caused excessive multi-axial bending and springing of the hull, and that the hull should have been structurally reinforced to cope with her increased length.
