From Who's Who:
Aquaman has the ability to directly communicate with most sea life. He is the only Atlantean possessing this trait. This telepathic power varies with the creature he is communicating with: for instance, a guppy will react as if it was given a command, but a dolphin may argue with him. He cannot make any creature do anything against its nature. Aquaman can receive thoughts within certain intelligence levels. Mostly he has the ability to sense primal emotions.
Aquaman can swim underwater over 87 n/mph (nautical miles per hour) or approximately 100 mph, slightly less on top of the water. Because of his dense body structure, Aquaman can withstand great pressure and changes in temperature. On land, Aquaman is much stronger than average humans, but his strength diminishes the longer he stays out of water. Under average conditions, Aquaman is at peak strength for about an hour, after two hours he is very weak, and will drop into a coma and be near death at the end of three hours. He is able to survive longer in a tropical rain forest than in a desert. To replenish himself, Aquaman must "breathe" water. This means anything from a quick shower to a long swim.
I would have to say about 2.
He should not be as strong as the current Disassembled Spider-man
He should easily be as strong as Wolverine or stronger.
Regardless he's still a loser.
