*Ships' names: The names NABSFIELD, NABSTEAD & NABSMERE were originally promulgated as being the names for MONABs VII, VIII, & IX respectively, (Special Military Branch Acquaint 2560, 16th December, 1944). For reasons which are not clear these units were renamed as NABREEKIE, NABCATCHER, & NABROCK. Since no other names appear to have been promulgated for the next units to form it is assumed that these names were still intended to be used by MONABs, and in the same order.
