By his own account, he had as a child conceived of mortar-launched lines as a means of reaching shoreline wrecks, many years in advance of George William Manby's successful implementation of the idea, and remained fascinated by shipwreck and rescue.

[3] Miller became acquainted with South Shields' lifeboat initiative, when he spent some days from 6 April 1789 undertaking work experience with a bookseller in the town.

1789 was a year in which the town was the 'epicentre of lifeboat innovation', arising out of the highly visible and protracted wrecking of a vessel, the Adventure, on the Herd Sands to the north-east of the South Shields on 14 March.

Lack of competent management of the affairs of the lifeboat station brought the Dunbar service to an end sometime after 1818, when damage occasioned to the Greathead boat went unrepaired, and it was found to be unavailable to assist with an 1821 wrecking.

The Sir Ronald Pechell Bt, valued at £208K in 2008, cost £1.05M to build in 1995 and in her 13 years of service at Dunbar had launched 206 times and rescued 171 people.

In 1907, to resolve this problem, it was decided that a satellite lifeboat station be established at Skateraw, 5 miles (8.0 km) to the south-east of Dunbar.
