On this dive I would be assisting Nate with the Wreck Adventure Dive for the Advanced Open Water certification class. While on our surface interval I switched over the students scuba tanks so they would be ready for the next dive. Again my job was to follow behind the group observing the students making sure they did not have any difficulties.
We descended onto to the YO-257 and briefly toured its deck. Since the Atlantis Submarine was not around right now, the current was mild, and the visibility was good we decided to venture over to the wreck of the San Pedro which lays next to the YO-257.
As Nate lead the group across the ocean bottom to the San Pedro I remained behind to make sure that all divers made it across between the ships safely . The Atlantis submarine tours back and forth between the shipwrecks so basically I acted like a crossing guard making sure the way was clear for the divers.
We toured the wreck of the San Pedro which is much more deteriorated than the YO-257 is and then swam back over to the YO-257. I could hear the Atlantis submarine in the area but could not see where it was at yet, so as we were crossing back over I kept looking for the Atlantis and making sure that no divers were left behind on the San Pedro.
Upon returning to the Yo-257 we began touring the openings that have been cut into its hull allowing the divers to swim through it for their first experience of penetrating a wreck. Since my penetration experiences during the Night Diver Specialty dives and the Wreck Diver Specialty dives I was able to do the penetrations without a problem. It also helped that I was able to keep my concentration on the students instead of what I was doing.
As we reached the mooring line and started our ascent the Atlantis submarine came into view just off the starboard side of the YO-257. As it got closer to the side of the YO 2 advanced divers that were not staying with our group were coming out of the holes in the side of the YO and were surprised by the Atlantis which was about 20 feet from them. They stayed close to the ships side and ascended up to the rest of us on the mooring line.
We ascended up the mooring line and made a 3 minute safety stop at 15 feet before climbing back onto the boat for our surface interval and lunch before our third dive.
