Our building time was slightly over 400 hours -- but the total cost for the hull with Fiberglas bottom, sink, head and hardware was under $800.

As it was, while Central wrangled among itself, Robert Tanner sneaked out of the pilots' barracks, out to the field and over to Helva's slim metal hull.

The first ironclad battleship, with iron armour over a wooden hull, La Gloire, was launched by the French Navy in 1859 ; she prompted the British Royal Navy to build a counter.

The following year they launched Warrior, which was twice the size and had iron armour over an iron hull.

The " open-topped " design format of the Panzerjäger vehicles was succeeded by the Jagdpanzer '(" hunting tanks ") which mounted the gun in true casemate-style superstructures, completely enclosing the crew compartment in armor that would usually be integral to the hull.

It was developed on the T-54 hull in 1951 ; series production started in 1955.

The hull was long and narrow, with a relatively shallow draft.

The bow was either raised in a forecastle or covered under a turtleback ; underneath this were the crew spaces, extending 1 / 4 to 1 / 3 the way along the hull.

The largest section comprising approximately two thirds of the centre hull was raised on 8 March 2001.

The SP and ID numbers were used parenthetically after each boat's or ship's name to identify it ; although this system pre-dated the modern hull classification system and its numbers were not referred to at the time as " hull codes " or " hull numbers ," it was used in a similar manner to today's system and can be considered its precursor.

For example, gun cruiser USS Boston ( CA-69 ) was converted to a gun / missile cruiser, changing the hull number to CAG-1.

Once an older NOAA ship leaves service, a newer one can be given the same hull number ; for example, " S 222 " was assigned to NOAAS Mount Mitchell ( S 222 ), then assigned to NOAAS Thomas Jefferson ( S 222 ), which entered NOAA service after Mount Mitchell was stricken.

The ship was similar in hull section to the Nydam ship with flaired topsides.

The raised prow extended about 3. 7m above the keel and the hull was estimated to draw 750mm when lightly laden.

The hull was waterproofed with animal hair, wool, hemp or moss drenched in pine tar.

From the outside the rope ran through the blade, through the round block and topsides and was fastened inside the hull.

In 1892-93 a full size near replica of the Gokstad ship, the viking, built by the Norwegian Magnus Andersen in Bergen. It was used to sail the Atlantic. It had a deeper keel with 1. 5m draught to stiffen the hull and a range of non authentic triangular sails to help performance and big fenders on each gunwhale filled with reindeer hair to give extra bouyancy in case of swamping.

The Schwimmpanzer II was a modified version of the Panzer II which, at 8. 9 tons, was light enough to float with the attachment of long rectangular buoyancy boxes to either side of the tank's hull.

The Tauchpanzer or deep-wading tank ( also referred to as the U-Panzer or Unterwasser Panzer ) was a standard Panzer III or Panzer IV medium tank with its hull made completely water-proof by sealing all sighting ports, hatches and air intakes with tape or caulk.

The term " frigate " implied a long hull design, which relates directly to speed ( see hull speed ) and also, in turn, helped the development of the broadside tactic in naval warfare.

The industry change to steel shot, arising from the US and Canadian Federal bans on using lead shotshells while hunting migratory wildfowl has also had an impact on reloading shotshells, as the shot bar and powder bushing required on a dedicated shotshell press also must be changed for each hull type reloaded, and are different than what would be used for reloading shotshells with lead shot, further complicating the reloading of shotshells.

The National Oceanic and Atmospheric Administration ( NOAA ), a component of the United States Department of Commerce, also uses a hull classification symbol system, which it also calls " hull numbers ," for its fleet.

Nearly all longships were clinker ( also known as lapstrake ) built, meaning that each hull plank overlapped the next.

Wooden slides were also installed along the barge ’ s hull to accommodate ten assault boats ( Sturmbooten ), each capable of carrying six infantrymen and powered by a 30hp outboard motor.

In theory this could also apply to the 4x and 8x, but most rowing clubs cannot afford to have a dedicated large hull which might be rarely used and instead generally opt for versatility in their fleet by using stronger shells which can be rigged for either sweep rowing or sculling.

They are also armed with numerous secondary phaser cannons mounted at other points across the hull, and they may carry a complement of photon torpedoes.

The speed that the boat is motored at also affects this-a lower speed can make a big difference to the energy required to move a hull.

A blimp with too long a hull may kink in the middle when the overpressure is insufficient or when maneuvered too fast ( this has also happened with semi-rigid airships with weak keels ).

Huckins also granted permission for Elco, Higgins and the Philadelphia Navy Yard to use their patented laminated keel, which increased hull strength.

It is also used to launch ships when a bottle is smashed over the hull during the ship's launch.

In the mathematical subfield of linear algebra or more generally functional analysis, the linear span ( also called the linear hull ) of a set of vectors in a vector space is the intersection of all subspaces containing that set.

All these hull types may also be manufactured as, or outfitted with, hydrofoils.

On a sailboat the word " keel " is also used to refer to the area that is added to the hull to improve its lateral plane.

In 1746 the first real shipyard was established on the Langewijk, initially only for the construction of timber flatboats, but after 1895 also for iron hull ships.

It is believed that the Kasota ( also known as the " Mighty Deuces ") was the last wooden hull tug in the Navy at the time.

In 1746 the first real shipyard was established on the Langewijk, initially only for the construction of timber flatboats, but after 1895 also for iron hull ships.

A conventional river-going jetboat will have a shallow-angled ( but not flat-bottomed ) hull to improve its high-speed cornering control and stability, while also allowing it to traverse very shallow water.

This capability is the result of a sail-plan and hull design.

As a result, the deposit is plated at different current densities which can be measured with a hull cell ruler.

The overall result was an extremely light and strong hull, yet it could be easily repaired from battle damage at the front lines.

The result is that a ship can run down or away from a schooner of the same hull length.

If the situation is reversed, with the center of pressure forward of the center of lateral resistance of the hull, a " lee " helm will result, which is generally considered undesirable, if not dangerous.

As a result the driver is seated forward in the hull ( in the center ) together with two infantrymen ( one on each side of the driver ).

One important modification carried out as the result of operational experience in Afghanistan was the fitting of a second layer of stand-off armour, usually a high resistant ballistic rubber-like material, to act as spaced armour around the top of the hull sides and around the turret.

As the hull was usually covered in barnacles and other marine growth, if the offender was pulled quickly, keelhauling would typically result in serious cuts, loss of limbs and even decapitation.

As a result of his death, safety laws became more stringent ; a safety harness and closed hull became compulsory, as was a twin hull design for boats.

The smaller ship also sank as a result of the collision after sustaining hull damage, and two crew members required treatment for hypothermia.

The result was the Sturmpanzer IV, which used a Panzer IV chassis with the upper hull and turret replaced by a new casemate-style armored superstructure housing a new gun, the Sturmhaubitze ( StuH ) 43 L / 12 developed by Skoda.

A line significantly shorter than the wavelength means the anchor and hull will ride over the crests together, while a line equal to the wavelength will keep the hull and anchor from ending up out of phase, which can result in severe loading on the anchor.

During the episode " Between The Darkness And The Light ", the viewer is shown the result of the organic technology being retrofitted onto the hull of the standard Omega design.

The company even offers a guarantee that, should anything harm you within a General Products hull as a result of a failure of these specifications, you ( or your estate ) will receive a very large sum of money (" tens of millions " of " stars " in the event of a death, with a " star " having value roughly equivalent to one United States dollar in the middle of the 20th century ).

After discovering multiple hull breaches as a result of possible weapons discharge, an away team is dispatched.

The cathedral hull configuration tends to result in a very broad bow ; many such boats are completely rectangular.

# A ship such as the Titanic turned by pivoting about a point approximately a third of the ship's length from the bow, with the result that with her rudder hard over, she could not have avoided crushing her entire starboard side into an iceberg were such a collision to occur, with the result that ' the hull and possibly the superstructure on the starboard side would have been rent.

Geronimo was the first elimination on 2 March, as a result of hull damage following a collision with flotsam.

Designer Gerry Douglas modified the hull to accept a higher cabin top and cruiser style cabin — the result was Catalina's largest sized offering for many years, and a strong product which is still in production, with roughly 1, 000 hulls on the water.
