They were of a traditional design by naval architects Graham and Woolnough, who are based in Liverpool, but boasted modern equipment including Crossley multi-speed engines for versatile control. They only had one single boarding gangway and their forward saloons extended to the whole width of the ship. This proved somewhat problematic especially at busy periods, so an additional gangway space was added on the promenade deck for use with the high level terminal gangways. The forward saloons also had facility for a bar area and dance floor, which meant the vessels could be used for cruising. The two vessels were primarily used on the Seacombe - Liverpool service, augmenting the New Brighton run during the summer seasons.
