1883 The station was opened at Mablethorpe to replace Theddlethorpe, three miles to the north.

1883 Lifeboat house constructed at a cost of £225 and a slipway for £50.

1889 Lifeboat was taken by road to Theddlethorpe on 27 November to go to the assistance of the Barque Elizabeth Argo but it was found that the lifeboat was not required. The horses had much difficulty in getting carriage through the snow taking four hours to travel four miles. In returning coxswain had boat's sails set to relieve strain on horses and got back to station in two and a half hours.

1895 Compensation of £17 paid for loss of a horse on service 13 January.

1900 New lifeboat house constructed on another site on the west side of the main road to Sutton at a cost of £700. Old lifeboat house sold for £50.

1907 A helper, Thomas Short, was run over by the carriage and a leg had to be amputated. Committee of Management voted £220 to his dependents.

1910 Acetylene beach lights supplied.

1917 Station temporarily closed as it was difficult to obtain a full crew in wartime.

1920 Owing to continuing shortage of crew, the station was closed permanently.

1965 Inshore lifeboat station established in May with the placing on service of a 'D' Class lifeboat.

1975 The Thanks of the Institution inscribed on vellum was accorded to Helmsman Bernard Tuplin and crew members John Mayfield and Michael Westfield in recognition of their courage, determination and skill displayed by them when the lifeboat rescued two swimmers who were in difficulties off an outfall pipe protected by a groyne structure, a quarter of a mile north of the lifeboat station in a light south easterly and a heavy surf on 6 August.

1980 A framed letter of appreciation signed by the Chairman of the Institution, The Duke of Atholl, awarded to the crew and helpers in recognition of their determination and skill when the crew of three of a coble were rescued. The coble which had engine trouble was towed to Mablethorpe. The lifeboat had to be launched under difficult conditions due to the heavy surf and the recovery of the lifeboat and coble was also hazardous.

1982 Framed letters of appreciation, signed by the Chairman of the Institution, The Duke of Atholl, presented to Helmsman William Tuplin and crew members John Mayfleld and Wayne Docking in recognition of their meritorious action when the lifeboat rescued the crew of three, two of whom were injured, from the barge Almeco on 12 October.

1996 New D class lifeboat D506 placed on service on 9 July.

1998 Bronze Medal awarded to the helmsman, Thomas Freeman for a service on the 12 April, when the D class inshore lifeboat rescued the crew of two and saved the fishing vessel Lark. Mablethorpe's lifeboat was launched in extreme conditions for this class of lifeboat to go to the assistance of the 17ft fishing vessel which had broken down in the surf off the coast. There was a Force 6 to near gale Force 7, wintry showers and a heavy swell. The helmsman had considerable difficulty in negotiating the rough seas in order to reach the fishing boat, which was drifting helplessly towards the shore, having lost her anchor. He decided that it was too hazardous to take off the crew and therefore passed a line and towed her away from danger - a considerable feat in the huge seas for a lifeboat smaller than the fishing boat and powered by one 40hp outboard engine.

Thomas Freeman was also awarded the 1998 'Miss Maud Smith's Reward for Courage in Memory of John 7th Earl of Hardwicke' for this rescue.

Medal record: One Bronze Medal awarded voted in 1998.
