There were two other classes of divers on the boat with us. We alternated dives with them, pulling on the cold wetsuits they just peed into. Yes, pee into your suit to warm it up.
This video is exactly how it feels to jump off the dive boat.
There were also some divers who were using the equipment.
They spent more time in the water than we did. Since it was really cold when we watched them submerge on the deep side of the boat into the dark, I was not jealous.
For the beginner class our first two open water training dives took place between 5 meters and 12 meters max. That's about 15 to 40 feet.
Then the last two dives were to 18 meters, or 60 feet.
