On Beira patrol on Minerva in 1970 we were due a Captain D's inspection. We were due for divisions but wet weather forced a cancellation and instead we had what we were told was a "muster by open list". Daddy D was set up in the cabin flat with the skipper's table and we had to march up to the table, chop one off and give name, ship's book number and number of good conduct badges that we had. We were told that this was an old tradition whereby the ship's books were checked to make sure that our captain wasn't entering non-existent ratings on the books then drawing their pay (and badge money) for himself. Since then I've occasionally tried to find out more information about this but so far no luck. Can somebody tell me if I'm right about the muster and where I can find out more.
