Halliday made a number of minor internal modifications in 1928 and she was re-engined with a 70 b.h.p. Thornycroft engine in 1935. Commenting on her performance in the Motor Boat in May 1935, He noted that "she has proved herself very able during extensive cruising in all conditions of weather around our coasts and her owner appears to be very satisfied."
Externally, 'Maralia' remains largely unchanged from Halliday's original design, the most obvious modification being the addition of a central wheelhouse. She is much loved by her current owner who lives aboard. He acquired her around 2000, at which time she was lying on the River Severn near Worcester and moved her to the east coast by lorry where she has remained since.
