Local people and supporters, including many divers, raised more than £300,000 for the boat, helped by a donation from the owner of teacake firm Tunnocks.
Boyd Tunnock gave £250,000 to the campaign to operate an independent lifeboat in the area which is popular with divers.
The boat will be named after his grandfather and late brother – Thomas Tunnock – in a ceremony in September.
The whole St Abbs community came out to welcome the new 9m long vessel, which was built by Marine Specialized Technology in Liverpool.
Over the next few months the St Abbs Independent Lifeboat crew will be trained on how to operate and handle the new lifeboat and all the new equipment.
The new lifeboat has been built to satisfy the “Rescue Boat Code” standard and the crew and committee will liaise closely with the Maritime and Coastguard Agency (MCA) to satisfy their criteria for achieving Declared Facility Status.
The new St Abbs Lifeboat will be officially launched on September 17th 2016 in a traditional lifeboat naming ceremony.
