On any boat I assume no one including crew and guests simply don't know how to with out for your UW rig.
I regularly would find a spot under a bench and maybe wrap my rig in a towel between dives. I was always afraid someone would drop their weight belt on it
I've actually seen people put all these on a CAMERA TABLE even after the crew tells them it's for CAMERAS !!!!
Masks, dry bags (WTF? Put your friggin' dry bag UNDER your seat or in your mesh bag!), regulators, dive computers (even giant console ones ATTACHED to their regulator!) and several times actual WEIGHT BELTS !!!!
I think newbie divers are just overwhelmed on their early salt water ocean trips. Maybe a bit nervous plus never were taught how to organize and control their gear.
I come from an era when you packed your gear bag in REVERSE order you put stuff on.
Take it out and set up BCD / regulator, next wet suit, last mask fins, etc.
When you come back aboard stow your stuff back in the bag! It's not that hard really.........
Sorry for the rant LOL......
