You don't have to calculate rock bottom for me. I'll do it for you, and we'll agree on what turn pressure is before we get in the water.

Benefits of registering include
ONE: Quarry dive, the visibility is 15 feet above the 'cline, 1 foot through the 'cline and 35 below it. Temperature is 76 at the surface and 68 below the 'cline. Would you dive as my buddy (or anybody else's for that matter).
TWO: Drift dive, warm water, 100+ foot vis (something I have absolutely no experience whatever with) in a group containing one DM of unknown quality.
THREE: Spiegel Grove, rough seas and strong current, average visibility. Dive plan calls for us not to exceed 90 feet or penetrate the ship.
My 2 cents, no for all 3, for a person to have to actually ask this is question , I can't see the desire to answer, which totally contradicts my response, but I digress
Is this like a trick question?

It is a rhetorical question... I am not actually searching for new dive buddies.
There are three methods of diving in current from an unanchored boat where you drift with the current. All three are commonly called "drift diving" although it is usually a misnomer.
Drift diving is rarely used. A weighted line, often the anchor line, is dropped to the desired dive depth. Divers descend along the line to the desired depth, holding on the line as the boat drifts along, they are always connected to the boat.
Live boating is common in Mexico, especially Cozumel. It is a fairly risky method. Divers descend and drift with the current. The boat follows the bubbles. Using this method, it is easy to lose divers or to accidentally strike a diver with the boat. Since safety sausages have become available, live boating has become safer.
The preferred method is float diving. It is similar to live boating, except one of the divers has a reel attached to a float, which the boat follows. Divers stay close to the diver with the reel and therefore do not get lost. Divers ascend next to the line and stay next to the float until acknowledged by the boat crew. They then swim away from the float for pickup. This ensures the boat does not strike divers.
That's a float dive.

I like doing rock bottoms together with my buddy. The point was to see if he dives "be back on the boat with 500" or not.
