You need to do a bit more traveling and diving. In the UK, on a hard boat, the skipper is normally a diver (or was in a past life)
So, in summary, you have an expectation that someone on the boat has knowledge and experience with the kind of diving you are diving?
Would you do a tech dive on one of those boats if you knew that the crew were all clueless about diving and the captain was fresh off getting his captain's license and his OW cert from some resort spot in the Caribbean? Maybe you would, but I would be pretty uncomfortable with that scenario.
