Design
Hashidate differed from her sister ship Itsukushima primarily in that her windows were rectangular instead of square, and in that she had a stronger engine.
As with Itsukushima, Hashidate had a steel hull with 94 frames constructed of mild steel, and a double bottom, divided into waterproof compartments, with the area between the bulkheads and armor filled with copra. The bow was reinforced with a naval ram. The vital equipment, including boilers and ammunition magazines, were protected by hardened steel armor, as were the gun shields. The main battery consisted of one breech-loading 320-mm Canet gun mounted in the bow of the ship, which could fire 450-kg armor-piercing or 350-kg explosive shells at an effective range of 8000 meters. The maximum rate of fire was two rounds per hour, and the ship carried 60 rounds. Secondary armament consisted of eleven QF 4.7 inch Gun Mk I–IV Armstrong guns, with a maximum range of 9000 meters and maximum rate of fire of 12 rounds/minute. Ten were mounted on the gun deck, five to each side, with the 11th gun located on the upper deck of the fantail. Each gun was equipped with 120 rounds. Tertiary protection was by six QF 6 pounder Hotchkiss mounted in sponsons on the upper deck, with a maximum range of 6000 meters and rate of fire of 20 rounds/minute. Each gun had 300 rounds. In addition, eleven QF 3 pounder Hotchkiss were mounted at various locations, with range of 2200 meters rate of fire of 32 rounds/minute and 800 rounds per gun. Each ship in the class also had four 356-mm torpedo tubes, three in the bow and one in the stern, with a total of 20 torpedoes carried on board. The weight of all of this weaponry made the design dangerously top-heavy, and armor was sacrificed in an effort to reduce weight.
The ship was driven by two horizontal triple expansion steam engines. However, the design had problems with seaworthiness, and was seldom able to attain its design speed of 16.5 knots in operation.

Famous quotes containing the word design:
“For I choose that my remembrances of him should be pleasing, affecting, religious. I will love him as a glorified friend, after the free way of friendship, and not pay him a stiff sign of respect, as men do to those whom they fear. A passage read from his discourses, a moving provocation to works like his, any act or meeting which tends to awaken a pure thought, a flow of love, an original design of virtue, I call a worthy, a true commemoration.”
—Ralph Waldo Emerson (1803–1882)
“Teaching is the perpetual end and office of all things. Teaching, instruction is the main design that shines through the sky and earth.”
—Ralph Waldo Emerson (1803–1882)
“Westerners inherit
A design for living
Deeper into matter—
Not without due patter
Of a great misgiving.”
—Robert Frost (1874–1963)
