I'm back.
We ended up diving the SG. That happened to be the location the dive operator was doing that day.
From what I have heard, it was a bit unusual on this dive.
There was no current on the surface or on the ship. Vis was 75'+ you could see it if you stuck your head under water. The bad thing was the waves. We had 6-7' with some 8-10' "Yeee Haw" waves, as the DM put it when they hit the boat. It was bad getting down. I slammed into my dad pretty hard about four times when we got to the bouy, it seemed like an eternity when it was only seconds. We weren't sure if there was a current on the ship, so we were trying to go down the line. It was a great dive, but the ship is soooooo big that it was a bit of a bummer. I lit my HID and cruised in a little ways into the covered part of the docking bay. I felt like an ant sitting on the dark side of the moon.
Anyway, thanks for all of the input. It helped to know what to expect.
I also learned a very important lesson. If you want to dive in larger waves, you have to go with an outfit that has real boats. We were planning on going out with a smaller outfit that had mostly 30' boats. My dad's is a 31' Aquasport and is nicer than their stuff. We ended up going out with Ocean Divers, they were awesome. Their Captain was top notch and the crew just as good.
Thanks again
Greg
