MASB 27 was built as a gunboat in 1941 by the British Powerboat Company at Hythe. She is of double diagonal construction  and her hull is of Honduras Mahogany.

She served in the Second World War first as a MASB and later possibly as a MGB. She was stripped to a bare hull in the 1980s and used as a houseboat.

The vessel is due to be transported to Somerset for a complete wartime restoration. She requires new decks, original design wheelhouse, stern gear, engines, artillery and partial refit below decks.

The restoration of MASB 27 is on track for re-launch in its wartime condition.  Her return to sea took place in May 2019, under her own power for the first time in 74 years and she is currently now being prepared for her first crossing to Normandy since 1944.
