https://www.captainalbert.com/current-captains-and-their-schedules/ this is where I found Frederick Carsjens, which doesn't sound familiar, but I'm going to look at the passport journeys sticker to be sure. Robert Jan Kan is there now, but I was talking about my previous 2 Koningsdam cruises, the most recent of which was Dec 2022.
Likely, she has had 2 awesome captains!!
