West Mersea Lifeboat Station is located on the Coast Road in West Mersea, at the western end of Mersea Island, situated between the Blackwater and Colne river estuaries, 10 miles (16 km) south of Colchester, in the county of Essex.

An Inshore lifeboat was first stationed at West Mersea by the Royal National Lifeboat Institution (RNLI) in July 1963.

The station currently operates a B-class (Atlantic 85) Inshore lifeboat, Just George (B-879), on station since 2014.

In 1962, the number of rescues or attempted rescues by All-weather lifeboats in the summer months was 98, with the number of lives rescued being 133. In 1963, in response to an increasing amount of water-based leisure activity, the RNLI began trials of small fast Inshore lifeboats, placed at various locations around the country. These were easily launched with just a few people, ideal to respond quickly to local emergencies. This quickly proved to be very successful. In 1963, there were 226 rescues or attempted rescues in the summer months, as a result of which 225 lives were saved.

One of the first places chosen for a new Inshore lifeboats was West Mersea, in Essex. A lifeboat station was established in July 1963, with the arrival of a D-class (RFD PB16) Inshore lifeboat, the unnamed (D-7). The lifeboat was housed in a shelter alongside the West Mersea Yacht Club. At the time, Inshore lifeboats were placed on station just for the summer season, and many boats were moved around to different stations. West Mersea are recorded as having seven different D-class Inshore lifeboats between 1963 and 1973.

In 1972, one of the first new larger twin-engined B-class (Atlantic 21) lifeboats, the unnamed lifeboat B-506, was placed at West Mersea. The D-class lifeboat D-108 was withdrawn to the relief fleet.

At 20:17 on Monday 31 July 1978, the West Mersea lifeboat Alexander Duckham (B-529) was launched to reports of two children missing in a canoe. En-route, with the weather now at force 7, the crew were informed that the two children were safe, but a flare had been sighted off Sales Point. Altering course, the lifeboat found the sloop Blackbird at anchor, but with her stern aground. Four people were rescued. A third reported incident diverted the lifeboat again, but turned out to be a false alarm. The Blackbird was recovered by a local fishing boat, with the lifeboat standing by. Helm Graham Knott was accorded 'The Thanks of the Institution inscribed on Vellum', with his two crew each receiving a 'Vellum Service Certificate'.

The Alexander Duckham (B-529) was launched at 17:00 on Saturday 26 May 1979, into a force 9 gale, to reports of a capsized dinghy. Arriving on scene to find nobody with the boat, crew member Jonathan French jumped into the water, to check the underside of the capsized boat, but found no-one. A search commenced, but the crew were later reported have made it ashore. Caught out by the conditions, several more boats were given assistance, with one man being recovered to hospital by a rescue helicopter. The lifeboat returned to base at 19:10. Helmsman James Albert Clarke was awarded 'The Thanks of the Institution inscribed on Vellum' for his seamanship, as was crewman French for his courage entering the water. Graham Knott was awarded a 'Vellum Service Certificate'.

By 1991, gifts, bequests, and a local fundraising appeal had raised £160,000, to provide West Mersea with a new lifeboat house, constructed 200 metres (660 ft) from the previous boathouse. Crew facilities were much improved, and the lifeboat now had direct access to the water. The station was formally opened on 10 September 1992 by H.R.H. The Duke of Kent.

Having had an Atlantic 21-class lifeboat on service for 29 years, West Mersea would receive the new improved Atlantic 75-class in 2001. The lifeboat was funded by the employees of Dignity Caring Funeral Services, who had raised over £81,000 with various fundraising events. The boat was duly named Dignity (ON 761)

The current lifeboat on station at West Mersea is an B-class (Atlantic 85), which arrived on station in October 2014. Over half the funding of the £214,000 lifeboat was from the bequest of Mr George Stribling of Weeley, Essex. At a ceremony on 31 May 2015, the lifeboat was named Just George (B-879) by TV personality Griff Rhys Jones OBE.
