A marine chronometer is a precision timepiece that is carried on a ship and employed in the determination of the ship's position by celestial navigation.

A depth charge is an anti-submarine warfare (ASW) weapon designed to destroy submarines by detonating in the water near the target and subjecting it to a destructive hydraulic shock.

Maneuvering thrusters (bow thrusters and stern thrusters) are transversal propulsion devices built into or mounted to either the bow or stern (front or back, respectively) of a ship or boat to make it more manoeuvrable.

A sea anchor (also known as a parachute anchor, drift anchor, drift sock, para-anchor or boat brake) is a device that is streamed from a boat in heavy weather.

A ship's wheel or boat's wheel is a device used aboard a ship, boat, submarine, or airship, with which a helmsman steers the vessel and controls its course.

An engine order telegraph or E.O.T., also referred to as a Chadburn, is a communications device used on a ship (or submarine) for the pilot on the bridge to order engineers in the engine room to power the vessel at a certain desired speed.

The International Convention for the Control and Management of Ships' Ballast Water and Sediments (Ballast Water Management Convention or BWM Convention) is a 2004 international maritime treaty which requires signatory flag states to ensure that ships flagged by them comply with standards and procedures for the management and control of ships' ballast water and sediments.

A sextant is a doubly reflecting navigation instrument that measures the angular distance between two visible objects.

A torpedo is an underwater ranged weapon launched above or below the water surface, self-propelled towards a target, with an explosive warhead designed to detonate either on contact with or in proximity to the target.

A diving suit is a garment or device designed to protect a diver from the underwater environment.

A diving bell is a rigid chamber used to transport divers from the surface to depth and back in open water, usually for the purpose of performing underwater work.

Gyrocompasses, such as the fibre optic gyrocompass are widely used to provide a heading for navigation on ships.

A hydrofoil is a lifting surface, or foil, that operates in water.

Aqua-Lung was the first open-circuit, self-contained underwater breathing apparatus (or "scuba") to achieve worldwide popularity and commercial success.

Scuba diving is an underwater diving mode where divers use breathing equipment completely independent of a surface breathing gas supply, and therefore has a limited but variable endurance.

The latter advantage over other systems is useful for covert military operations by frogmen, as well as for undisturbed observation of underwater wildlife.

A hovercraft (pl.: also hovercraft), also known as an air-cushion vehicle or ACV, is an amphibious craft capable of travelling over land, water, mud, ice, and various other surfaces.

The Bathysphere (from Ancient Greek βαθύς (bathús) 'deep' and σφαῖρα (sphaîra) 'sphere') was a unique spherical deep-sea submersible which was unpowered and lowered into the ocean on a cable, and was used to conduct a series of dives off the coast of Bermuda from 1930 to 1934.

Propulsion of watercraft (as a paddlewheel) Low head hydro power (as a waterwheel) Flow sensors Aerators The paddle wheel is an ancient invention but is still used today in a wide range of industrial and agriculture applications.

Marine radars are X band or S band radars on ships, used to detect other ships and land hazards, to provide bearing and distance for collision avoidance and navigation at sea.

In a rotor ship, the rotors stand vertically and lift is generated at right angles to the wind, to drive the ship forwards.

A compass is a device that shows the cardinal directions used for navigation and geographic orientation.

Frederick Otis Barton Jr. (June 5, 1899, April 15, 1992) was an American deep-sea diver, inventor and actor.

Émile Gagnan (1900-1984) was a French engineer and, in 1943, co-inventor with French Navy diver Jacques-Yves Cousteau of the Aqua-Lung, the diving regulator (a.k.a. demand-valve) used for the first Scuba equipment.

Jacques-Yves Cousteau (, also UK: ; French: [ʒak iv kusto]; 11 June 1910-25 June 1997) was a French naval officer, oceanographer, filmmaker and author.

Ole Evinrude, born Ole Andreassen Aaslundeie (April 19, 1877, July 12, 1934) was a Norwegian-American entrepreneur, known for the invention of the first outboard motor with practical commercial application.

John Hadley (16 April 1682-14 February 1744) was an English mathematician, and laid claim to the invention of the octant, two years after Thomas Godfrey claimed the same.

Echo sounding or depth sounding is the use of sonar for ranging, normally to determine the depth of water (bathymetry).
