Notes:

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.

Notes:

This was my first dive for the practicals portion of my Dive Master course. Today I assisted Nate Jonson with the Deep, Wreck, and Drift Adventure Dives of an Advanced Open Water course for 2 students.

My job today started off with preparing and loading scuba tanks on the boat for a total of 15 divers, then selecting the wetsuits, BCD’s, regulators, computers, fins, and masks for the divers who did not bring their own with them. Actually this was the hardest part and most stressful of the day. I am so bad at guessing peoples equipment sizes based on their height and weight, especially with the females. I have been slapped too many times by females for guessing their weight incorrectly while growing up that I suppose I am “scarred” from the experiences.

With assistance from Nate I was able to get all of the divers gear ready for them before they arrived at the Island Divers Hawaii dive shop in Hawaii Kai, and all of the gear was the correct size for them.

Our first dive would be the Sea Tiger which was highly requested by several of the divers (not just me). I have been waiting since starting to dive in January for a chance to dive the Sea Tiger. We normally only do this dive location with our three tank dives on Sundays, so I have never had an opportunity to do this dive yet and I was excited for the chance. After an initial weight check at the surface and assisting a PADI Course Director who was visiting from the mainland with adding additional weights to her BCD we started our descent down to the Sea Tiger.

Since I was diving Nitrox today I could not descend all the way to the bottom which was about 120′ with Nate and the students. Instead I hovered above them at the deck of the Sea Tiger at 97′ while observing them go through their skills. Once they had completed the required skills for the deep dive they joined me on the deck for a tour of the ship. My job then was to follow along behind the group which was lead by Nate observing the students for possible hazards and making sure they did not have any problems on the dive.

After taking a tour around the Sea Tiger we started our ascent back up to the boat. At the mooring line I reminded the students to deflate their BCD’s for the ascent so that they would not be too buoyant while coming back up. At 15 feet we made a 3 minute safety stop and then surfaced and climbed back onto the boat without incident.

Because I was assisting with the class today as a DMC (Dive Master Candidate) I carried extra weights in my BCD pockets in case the students needed additional weights. I only carried 2 additional 2 pound weights, but I could really feel the difference as I was very overweighted.

Notes:

This was the fourth and last dive for the Wreck Diver Specialty course.

Since the current was so strong today and I had not mapped this wreck we decided not to have me deploy a penetration line on the YO-257 and opted for just a “fun dive” to explore the wreck. I had dove this wreck once back in early March for my Advanced Open Water certification, but we stayed on the outside of it and did not venture inside. This dive we would penetrate the wreck to help me overcome my claustrophobia.

As we descended on the YO-257 the visibility had dropped from our previous dive and I was not able to see the wreck until we descended past the buoy and were approaching it. The first thing I was able to see was the Nautilus submarine which takes tourist on a tour of the YO-257 and the San Pedro which is sunk beside it. On my last dive here you could see the San Pedro from the YO-257

I saw several large jelly fish which concerned me because of my allergy to their stings. I always keep an Epi Pen in my dive bag just incase I have an anaphylactic reaction to them. This is also why I dive with a full wetsuit, hood, boots, and gloves to cover up and protect everything that I possibly can cover.

On this dive Nate my instructor played tour guide as I followed him inside the wreckage of the YO-257. We swam through several areas of the ship seeing the sea life that call the YO home including a very large Moray Eel that was hanging out above a rusted pipe inside. There was also another Moray Eel that found a nice home in a round port hatch on the ships starboard hull that did not seem very happy to be disturbed from his sleep.
