Anchorage (maritime) in the context of "Spithead"

Palmyra Atoll (/pælˈmaɪrə/), also referred to as Palmyra Island, is one of the Northern Line Islands (southeast of Kingman Reef and north of Kiribati). It is located almost due south of the Hawaiian Islands, roughly one-third of the way between Hawaii and American Samoa. North America is about 3,300 miles (5,300 kilometers) northeast and New Zealand the same distance southwest, placing the atoll at the approximate center of the Pacific Ocean. The land area is 4.6 sq mi (12 km), with about 9 miles (14 km) of sea-facing coastline and reef. There is one boat anchorage, known as West Lagoon, accessible from the sea by a narrow artificial channel and an old airstrip; during WW2, it was turned into a Naval Air Station for several years and used for training and refueling. It was shelled by a submarine in December 1941, days after the Attack on Pearl Harbor, but was not the site of a major battle. Palmyra has, over time, had many of its islets merged together, so the actual amount of contiguous land depends on the tide and locations of sandbanks. For example, Strawn, Menge, and Cooper Islands are one contiguous island. Likewise, there are many shoals and coral heads on the atoll, which is ringed by a coral reef.

It is the second-northernmost of the Line Islands and one of three American islands in the archipelago, along with Jarvis Island and Kingman Reef. Palmyra Atoll is part of the Pacific Islands Heritage Marine National Monument, the world's largest marine protected area. The atoll comprises submerged sand flats along with dry land and reefs. It comprises three lagoons separated by coral reefs. The western reef terrace is one of the biggest shelf-reefs, with dimensions of 2 by 3 miles (3.2 by 4.8 km). Over 150 species of coral inhabit Palmyra Atoll, double the number recorded in Hawaii.

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.

The State of India, also known as the Portuguese State of India or Portuguese India, was a state of the Portuguese Empire founded seven years after the discovery of the sea route to the Indian subcontinent by Vasco da Gama, a subject of the Kingdom of Portugal. The capital of Portuguese India served as the governing centre of a string of military forts and maritime ports scattered along the coasts of the Indian Ocean.

Francisco de Almeida, the first viceroy, established his base of operations at Fort Manuel in the Malabar region, after the Kingdom of Cochin negotiated to become a protectorate of Portugal in 1505. With the Portuguese conquest of Goa from the Bijapur Sultanate in 1510, Goa became the major anchorage for the Armadas arriving in India. The capital of the viceroyalty was transferred from Cochin to Goa in 1530. From 1535, Mumbai (Bombay) was a harbour of Portuguese India, known as Bom Bahia, until it was handed over to Charles II of England in 1661 as part of the dowry of Catherine de Braganza. The expression "State of India" began regularly appearing in documents in the mid-16th century.

Yerba Buena was an anchorage spot and later a settlement that grew into the city of San Francisco, California. The settlement, built in an area known earlier as El Paraje de Yerba Buena and named for an herb that grew abundantly there, was founded in 1834 and was located near the northeastern end of the San Francisco Peninsula, on the shores of Yerba Buena Cove. Yerba Buena was the first Spanish colonial or Mexican civilian settlement in San Francisco, which had previously only had indigenous, missionary, and military settlements, and was originally intended as a trading post for ships visiting San Francisco Bay. The settlement was arranged in the Spanish style around a plaza that remains as the present day Portsmouth Square. The area that was the Yerba Buena settlement is now in the Financial District and Chinatown neighborhoods of San Francisco.

Royal Navy Dockyards (more usually termed Royal Dockyards) were state-owned harbour facilities where ships of the Royal Navy were built, based, repaired and refitted. Until the mid-19th century the Royal Dockyards were the largest industrial complexes in Britain.

From the reign of Henry VII up until the 1990s, the Royal Navy had a policy of establishing and maintaining its own dockyard facilities (although at the same time, as continues to be the case, it made extensive use of private shipyards, both at home and abroad). Portsmouth was the first Royal Dockyard, dating from the late 15th century; it was followed by Deptford, Woolwich, Chatham and others. By the 18th century, Britain had a string of these state-owned naval dockyards, located not just around the country but across the world; each was sited close to a safe harbour or anchorage used by the fleet. Royal Naval Dockyards were the core naval and military facilities of the four Imperial fortresses - colonies which enabled control of the Atlantic Ocean and its connected seas. The Royal Dockyards had a dual function: ship building and ship maintenance (most yards provided for both but some specialised in one or the other). Over time, they accrued additional on-site facilities for the support, training and accommodation of naval personnel.

A roadstead or road is a sheltered body of water where ships can lie reasonably safely at anchor without dragging or snatching. Protected from rip currents, spring tides, or ocean swell, a roadstead can be open or natural, usually estuary-based, or may be created artificially. In maritime law, it is described as a convenient or safe place where boats usually anchor.
