I was thirty years at sea,catering side with usual Vindi training. Reading all the above posts (incuding other one Bill) I recall all the young deck apprentices/cadets I have sailed with since 1947 and later engineering apprentices. They worked bloody hard and were expected to do all the mucky deck jobs besides their study work before being able sit their tickets. It was always nice to come across them later when sporting a ring or two on their uniform jackets. They earned it....
