The strength of ships is a topic of key interest to naval architects and shipbuilders. Ships which are built too strong are heavy, slow, and cost extra money to build and operate since they weigh more, whilst ships which are built too weakly suffer from minor hull damage and in some extreme cases catastrophic failure and sinking.
In September 1964, Time magazine reported on the vehicle's unique specifications, stating that its 51-foot (16 m) hull consists of 11 forged cylinders. Aluminum's strength-to-weight ratio exceeds that of steel, so Aluminaut 's 6.5-inch-thick (170 mm) shell could withstand pressures of 7,500 pounds per square inch (52 MPa) at the sub's 17,000 ft ...
A hull is the watertight body of a ship, boat, submarine, or flying boat. The hull may open at the top (such as a dinghy), or it may be fully or partially covered with a deck. Atop the deck may be a deckhouse and other superstructures, such as a funnel, derrick, or mast. The line where the hull meets the water surface is called the waterline.
Naden Boats is a line of aluminum fishing boats manufactured in Canada by Temagami Boat Manufacturing Inc. Six models are offered, ranging from 11’11" to 16’ in overall length. They are noted for their expanded polystyrene flotation, rigid construction, and semi-V planing hull with five keels.
Aluminum and aluminum alloys are used both in sheet form for all-metal hulls or for isolated structural members. Many sailing spars are frequently made of aluminium after 1960. It is the lightest material for building large boats (being 15–20% lighter than polyester and 30% lighter than steel).
The Cruising Club of America (CCA) put together a technical committee that analyzed race boat data. They came up with the formula to compare boats based on readily available data. The CCA characterizes the formula as "rough". A lower value is supposed to indicate a sailboat is less likely to capsize. A value of 2 is taken as a cutoff for ...
U-995, a U-Boat of WWII, showing the typical combination of ship-like non-watertight outer hull with bulky strong hull below. A submarine hull has two major components, the light hull and the pressure hull. The light hull (casing in British usage) of a submarine is the outer non-watertight hull which provides a hydrodynamically efficient shape ...
This is the maximum depth at which a submarine is permitted to operate under normal peacetime circumstances, and is tested during sea trials.The test depth is set at two-thirds (0.66) of the design depth for United States Navy submarines, while the Royal Navy sets test depth at 4/7 (0.57) the design depth, and the German Navy sets it at exactly one-half (0.50) of design depth.
