OP -- I hope I understand your concern and why you've asked the question. I've certainly seen/heard dive ops cajole people into doing dives that perhaps they shouldn't be doing -- with the typical "Oh, OK, you've just been OW certified, but there are some really cool sharks down around 85 feet. You shouldn't have a problem." when, in fact, just getting down the anchor line could be a problem.
OTOH, at 50 dives I'd hope you'd have sufficient experience to do most any "normal" recreational dive and wouldn't give the particular dive op a second thought.
I feel sorry for "divers" who have been led to believe they need a card for EVERY type of diving they do instead of slowly expanding their experience by, well, diving! I just taught a PADI specialty class (Nitrox) and was talking with one of the students about his diving plans. I suggested he sign up for some boat dives sponsored by a local dive club -- "But I don't have my Boat Diving Cert" was his response. When I suggested he do some diving after work with a group of very good divers he said "But I don't have my Night Diving Specialty yet" and so he thought he shouldn't/couldn't do one -- even with a mentor. THAT, to me, is a sad comment.
Where you fit in that spectrum I have no idea. As an instructor I certainly advocate for taking classes and/or diving lessons -- but I also urge people to just go diving. One of the best pieces of advice I've received was "Get out of [the local diving spot] and go get your *sses handed to you!" Some times you just have to stretch your comfort zone -- but stretch only one thing at a time!
