Sauron in Numenor

[Hot, crispy nice hobbit]

So...
1. Sauron had the Ring on Numenor.
2. He had the ring when Atlantis sunk.
3. His physical form perished when Atlantic sunk.
4. Without a physical form, He carried the Ring over the realm of Ulmo (why didn't that guy grap the ring, by the way?)
5. He took a physical form and returned to Mordor.

All this begs THE question, which is how did Sauron transport the Ring to land if his physical form is already gone?

But Sauron was not of mortal flesh, and though he was robbed now of that shape in which he had wrought so great an evil, so that he could never again appear fair to the eyes of Men, yet his spirit arose out of the deep and passed as a shadow and a black wind over the sea, and came back to Middle-Earth and to Mordor that was his home.

Okay, re-phrasing a little:
1. Sauron's physical form drowned when Atlantis sunk.
2. Somehow, the Ring did not sink.
3. The spirit of Sauron rise from the sea.
4. It graps the ring with spirit hands.
5. It transform into a typhoon and fly with the Ring to Mordor.

The Ring is Fea, Sauron was, for a while, a houseless spirit. So I guess Sauron should not have been capable of carrying the Ring. So here are some of my twisted theories...

Theory number 2:
1. Sauron's physical form drowned when Atlantis sunk.
2. The Ring was washed away by tsunami.
3. Sauron's spirit rise from the sea, and find that the Ring is gone!
4. The Ring wash towards Middle-Earth, was swallowed by a fish. (Fish turned invisible)
5. Sauron transformed into typhoon, fly towards Mordor.
6. Once there, Sauron ordered all orcs and men to begin fishing for invisible fish.

Bonus theory 3:
1. Sauron's physical form drowned when Atlantis sunk.
2. The Ring sunk, and hit Osse on the head.
3. Osse, being buddy of Melkor in the early days, carried it up to the surface.
4. Sauron's spirit transformed into Black wind, and blow the Ring towards Mordor.

Are there other more plausible theories?
