Well, I try not to... :)
You described a scene near the end:
"the old guy looks with a sextant then points and shouts "that way!" "
See below (attached). This is one of those cases where the movie fouls its post-aquacalypse dystopian view. They chose a sextant from a hundred years ago. A sextant from 1990 would have made more sense, but that wouldn't have fit in with their weird, pirate-y, "marine mad max" artistic vision. By the way, right after pointing "that way!", the ballooners fire up two propellers each about 10 inches in diameter, and they're off. Yeah, that'll do it!
While we're at it (Waterworld and all), below (attached) you'll find the updated sea level data for the tide gauge at the Battery at the south end of Manhattan, NYC, one of the longest running tide gauge data sets in the world. Sea level continues to rise at the same slow pace it has shown since the last third of the 19th century --about one foot per century. There is, as yet, no significant acceleration. The rate of sea level rise was roughly the same in 1915 as it is in 2015.
