Mary Mouse

Outside the marina at Haslar opposite Portsmouth is Light Vessel number One AKA Mary Mouse 2. She was the first light vessel to be commissioned by Trinity House after the Second World War, built by Phillips and Son Ltd in Dartmouth at a cost of £50,392. She was posted to various sites along the English Channel. Light vessels are not typically self-propelled so she was always towed to location regardless of weather.



She was manned with a Master and six crew on rotating shifts of four weeks on, two weeks off, and the crew would spend spare time radioing back weather reports to the Met Office and doing basic maintenance. Crew changes were by boat but later a helicopter pad was added to make crew replacement safer and easier.

In 1983 she was fully automated so was unmanned until her retirement as lightships were replaced by LANBY buoys.



Sold by Trinity House in 1993, John Dean and Richard Reddyhoff saved her from the scrap yard and had the vessel towed to Poole Quay for a head scratch and a think. Major modifications were carried out, including: a new lower deck amidships; addition of portholes, doors and windows; installation of shower cubicles; addition of bar, restaurant, galley, etc; marquee, and a colour change. Large pile guides were also added to anchor the vessel pontoon style on piles to the sea bed. LV1 was then renamed ‘Mary Mouse 2’ (after Mary Reddyhoff and Joanna ‘Mouse’ Dean)


Following the refit Mary Mouse 2 entered service at the Dean & Reddyhoff Haslar marina.
