Most off site dive tops will keep all your gear for you. Post COVID you keep your reg. Some don't do wetsuits, so it would not be that much.
So my preferred dive op for over 10 years wants you to take all your dive gear every day off the boat, which is everything except for tanks and weights which they provide. You forgot about the camera gear. At my age it's just to much weight to haul twice a day at the the distance to the other pier. I go on vacation to relax and dive. Will wait until Apr/May of 2021 to dive Cozumel again. In the meantime will do Roatan and Cayman Brac.
