The image shows a small military ship, armed, mechanically propelled, by an aircraft engine with propellers or turbines, provided with sets of metal wings joined by the body through supports called struts, viewed from side and directed to the left.
The ship, also called a hydrofoil, is a military vessel, different from the others by its movement above water level, due to the wing structure mounted below the hull, that at maximum speed, develop enough lift to raise the hull out of the water, providing the ship with a high speed.
Hydrofoils are used as patrol boats along the coast or as destroyers. Destroyers with hydrofoil technology are of two types: missile boats and torpedo boats, equipped with torpedo launchers.
The outer shell of the ship is called the hull and is shown embossed, has an elongated, rectangular shape, wide in the middle of the superstructure and narrowed towards the ends, where it extends to the top or bow, left and tail or stern, right.
The fore superstructure or twin island is the highest construction on the upper deck of the ship, from where the ship is steered. Here it is rendered by an elevation of the hull in the center, like a horizontal and embossed rectangle.
The windows of the twin island are on the left edge, rendered as three small, blank squares, arranged horizontally.
The military hydrofoil consists of the essential workstations:
- the twin superstructure or twin island on the center of the deck, where are: the navigation bridge, the fire control director, chart room.
- above the superstructure are installed: the central firing control system, radar and surveillance systems, the armored control tower and the aft mast tripod.
- next to the twin island is an armored cannon from the stern, right, and the deck gun two turrets from the bow, left.
To the left of the superstructure, on the forecastle, is the deck gun two turrets, rendered as thick oblique lines joined on the right by an embossed square and are directed to the left.
The cannon at the right end, at the stern, is dome-shaped and is marked embossed, with a horizontal and thickened rectangle, joined by the body.
Below the left hull of the ship, there are, joined on the side, two wings, similar to rectangular and vertical beams, metallic, rendered by dotted texture.
At the opposite end, right, under the hull, is the propeller that provides the ship with great power to move at speeds high enough to lift the body above the water.
