The old Vickers Vanguard ( Merchantman ) was fitted with a " STAN ",
I canīt remember what it stood for. However, as soon as the freighter
moved it displayed a rough indication of weight and trim, which was then
compared with the load/trim sheet figures. It worked perfectly and saved " big mouth ", one of our load controllers, from getting into serious trouble
when STAN indicated a ten ton weight difference. I know it wasnīt perfect, but it was helpful.
