343 Can YOU man a BOAT? As an extension of a Yachtsmen's Emergency Scheme already in existence, YACHTSMEN AND OTHERS with motor boat or steam boat ex- perience, either as seamen or engineers, ARE INVITED to put their services at the disposal of the Royal Navy for short periods of duty during the next six months. Volunteers would be required to serve in harbour service craft and other small vessels, thus releasing trained naval ratings for general service. Each period of duty will be from three to four weeks' duration, but no individual who is required to obtain an employer's permission to serve will be called upon more than once during the complete cycle.
