Tenby's new ILB house was dedicated on Sunday, September 11, 1977, when The Hon. Manning Philipps, MBE, Lord Lieutenant for Dyfed, declared the boathouse open and unveiled a commemorative plaque. The service of dedication was led by The Right Reverend The Lord Bishop of St David's. The cost of the boathouse was about £12,000. At the ceremony a cheque of £7,000, raised locally over and above normal branch and guild fund-raising activities, was presented by Walter Bushel, chairman of the station branch, to Raymond Cory, a Vice-President of the RNLI and a member of the Committee of Management.

Between the opening ceremony and mid October a further £3,000 had been raised..
