Jetty in the context of "Carlsbad, California"

A breakwater is a permanent structure constructed at a coastal area to protect against tides, currents, waves, and storm surges. Breakwaters have been built since antiquity to protect anchorages, helping isolate vessels from marine hazards such as wind-driven waves. A breakwater, also known in some contexts as a jetty or a mole, may be connected to land or freestanding, and may contain a walkway or road for vehicle access.

Part of a coastal management system, breakwaters are installed parallel to the shore to minimize erosion. On beaches where longshore drift threatens the erosion of beach material, smaller structures on the beach may be installed, usually perpendicular to the water's edge. Their action on waves and current is intended to slow the longshore drift and discourage mobilisation of beach material. In this usage they are more usually referred to as groynes.

A mooring is any permanent structure to which a seaborne vessel (such as a boat, ship, or amphibious aircraft) may be secured. Examples include quays, wharfs, jetties, piers, anchor buoys, and mooring buoys. A ship is secured to a mooring to forestall free movement of the ship on the water. An anchor mooring fixes a vessel's position relative to a point on the bottom of a waterway without connecting the vessel to shore. As a verb, mooring refers to the act of attaching a vessel to a mooring.

The term likely stems from the Dutch verb meren (to moor), used in English since the end of the 15th century.

Mustang Island is a barrier island on the Gulf Coast of Texas in the United States. The island is 18 miles (29 km) long, stretching from Corpus Christi to Port Aransas. The island is oriented generally northeast–southwest, with the Gulf of Mexico on the east and south, and Corpus Christi Bay on the north and west. The island's southern end connects by roadway to Padre Island. At the northern end of the island is Port Aransas, beyond which is San José Island. The Aransas Channel, also known as the "Aransas Pass", which separates Mustang Island from San José Island, is protected by jetties extending into the Gulf from each island.

The town of Port Aransas is located at the northern end of the island. Mustang Island State Park encompasses the entire southern third of the island, including 3,955 acres (1,600 ha) and 5 miles (8 km) of beach. The city of Corpus Christi includes the northernmost portion of Padre Island and part of Mustang Island between Port Aransas and the state park.

Trolling is a method of fishing where one or more fishing lines, baited with lures or bait fish, are drawn through the water at a consistent, low speed. This may be behind a moving boat, or by slowly winding the line in when fishing from a static position, or even sweeping the line from side-to-side, e.g. when fishing from a jetty. Trolling is used to catch pelagic fish such as salmon, mackerel and kingfish.

In American English, trolling can be phonetically confused with trawling, a different method of fishing where a net (trawl) is drawn through the water instead of lines. Trolling is used both for recreational and commercial fishing whereas trawling is used mainly for commercial fishing.

Southend Pier is a major landmark in Southend-on-Sea, Essex, United Kingdom. Extending 1.33 miles (2.14 km) into the Thames Estuary, it is the longest pleasure pier in the world. The bill to build the new pier, to replace a previous timber jetty, received royal assent as the Southend Pier Act 1829 (10 Geo. 4. c. xlix) in May 1829 with construction starting in July 1829. The timber pier was replaced by an iron pier that opened to the public in August 1889. The Southend Pier Railway, opened in the early 1890s, was the first pier railway in the country.

The pier played a role through both of the world wars, such as during World War I when ships housing German prisoners of war were moored off the pierhead. In the Second World War, the pier was taken over by the Royal Navy and was renamed HMS Leigh, closing to the public in September 1939. Following the war, around six million people visited the pier in 1949, exceeding pre-war visitor numbers, with new attractions opening during the 1950s. A period of decline began during the 1970s, with structural deterioration that led the council to announce closure plans in 1980. Following protests, the pier remained open and a grant in 1983 allowed renovation work to take place, including for a new pier railway that was opened in May 1986 by Princess Anne.
