Imagine living out in the isolated sea on the Maunsell Forts.

Maunsell Forts are a group of buildings that were erected in the ocean for the defence of the United Kingdom, in Europe, near the mouths of the River Thames and the River Mersey.
Maunsell Forts were built for use in World War II, serving as forts for either the navy or the army, depending on the fort, with the army forts consisting of a set of seven connected towers.
Four navy forts and three army forts were built in the Thames estuary as part of the Maunsell Fort system, named ‘Rough Sands’, ‘Sunk Head’, ‘Tongue Sands’, ‘Knock John’, ‘Nore’, ‘Red Sands’ and ‘Shivering Sands’, numbered U1-U7 respectively, and are collectively known as the ‘Thames Sea Forts’.
Observing, searching for and halting German aircraft and other threats, during World War II, were the primary uses of the Maunsell Forts.
The main material used in the construction of Maunsell Forts was concrete and steel, with the navy forts sitting on a flat bed supported by two cylindrical columns, and the army fort towers sitting atop four cylindrical legs that sit like a square pyramid.

Maunsell Forts were designed by engineer Guy Maunsell from Britain, hence their name, and were built in the early 1940s.
A number of Maunsell Forts or towers have been destroyed since World War II, due to watercraft collisions and weather conditions, while the forts in the Mersey estuary were removed due to the hindrance to ships travelling in the area.
By the 1950s the Maunsell Forts were no longer used for their original purpose and were mostly left abandoned, however, during the 1960s, a number of the forts were overtaken by pirates as a base to broadcast pirate radio.
Many of the remaining Maunsell Forts are in a state of deterioration and they can be quite hazardous to approach, so viewing is generally performed from a distance.
Restoring the Maunsell Forts has been considered, and a preservation project, known as Project Redsand began in 2003 to restore the Red Sand towers so that they could be used commercially for communications, recording of music, experiments, and history related activities.

Lets shorten Assault Amphibious Vehicle to AAV.

AAVs are used for land and sea military operations, generally around the beach.
The marines call AAVs “amtracks”, which is short for amphibious tractor.
An AAV was originally known as a “Landing Vehicle, Tracked, Personnel-7” or LVTP-7.
AAVs are generally equipped with a grenade launcher, a heavy machine gun, crew radios, and an intercom system.
AAVs have the capacity to hold 21 equipped troops, and four crewman – the driver, commander, gunner, and a rear crewman.

AAVs were originally LVTD-7s which were first made in 1972 and converted to AAV-7A1s in the 1980s.
An AAV-7A1 weighs 29.1 tons (26.4 tonnes), and is 7.94 meters (26 feet) in length, 3.27 meters (10.7 feet) in width and 3.26 meters (10.7 feet) in length.
The AAV-7A1 can travel over speeds of 24.32 km per hour (15 mph) off road, 72 km/h (45 mph) on road and 13.2 km/h (8.2 mph) in water.
The replacement cost of an AAV is over two million dollars.
The Expeditionary Fighting Vehicle (EFV) was due to replace AAVs in 2015, but the plans have been cancelled.
