I have sailed with a few companies that were busy sending Deck Officers on training courses for all sorts of things. ECDIS, Bridge Management, Radar, DP, etc. When I asked if they were sending Engineers on training courses I got a rather blank look and was was told that the Engineers already had their tickets, and was asked why we needed to go on any extra Training Courses??
It is always better to ask a stupid question than to do a stupid thing.
