The D class lifeboats were called MyWay and MyJo after Marjorie Gallon and her late husband Joe at an official naming ceremony last weekend.
Sunderland Royal National Lifeboat Institution, RNLI, lifeboat operations manager Martin Andrew said the boats had been provided thanks to the “very generous” legacy of Mrs Gallon who died in 2007 aged 86.
MyWay, named by friends Sue and David Roberts because Mrs Gallon was known for doing things ‘her way’, was launched in October.
It operates at RNLI stations along the coast, providing cover when their usual lifeboats are being repaired or refitted.
MyJo, an inshore boat working alongside the larger Atlantic 85 class vessel Wolseley, has already completed ten rescues since it went into service last November.
Mrs Roberts, who is a member of the RNLI Hall Green and Acocks Green Guild, said: “She would be delighted to know that the two lifeboats are going to be named in her honour and I know it is the sort of occasion she would have loved.”
An RNLI spokesperson added: “We are so grateful to Mrs Gallon for remembering the RNLI and Sunderland in particular in her will.
“Her legacy will live on saving lives at sea for many years to come.”
