1) what is the farthest point from any continental land
2) what point of land is farthest from any point of seawater
3) considering currents and winds, what point of the ocean's surface would cause you to be stranded on a raft for the longest time (i.e. from this point, it would take the longest time to drift to land)

Answer 1

Looking at a globe, the vicinity of Tahiti (20 deg. S, 150 W) looks to be about equidistant from Australia, Peru, and Mexico.

In Central Asia, look where Russia, Kazakhstan, Mongolia, and China's Xinjiang Province all come together (50 N, 90 E), or maybe just a bit west of there. That seems equidistant from the Arabian Sea, Bay of Bengal, and Arctic Ocean.

I don't know your third one, but my guess is somewhere in the western Pacific below the Equator. Would have to look at current and wind charts though. I think Magellan got stranded there. On the other hand, it might be somewhere in the Indian Ocean (depending again on charts) because the South Pacific has a lot more islands than the Indian.

Answer 2

1 It's a point in the South Pacific Ocean about 3/4 of the way from New Zealand to South America. The closest land is Cape Dart, Antarctica. You sail very close to this point on the way to New Zealand around Cape Horn.
2 A point in Western China.
3 The Sargasso Sea in the north Atlantic. All the seaweed and flotsam ends up there because of the clockwise current system in the north Atlantic. Just like when you stir a cup of coffee and all the bubbles end up in the centre.
