Even if it took similar transit time, it would be half the cost, and you don't have to go SFO first :)

High winds and weather systems occasionally effect air travel, but once flying above the water at 10m, you can fly over normal ocean swell conditions. The introduction of the foils is a key for making the seaglider comfortable from the inner harbors to the outer harbor in realistic operation conditions (wind/wave combinations).

Mike (CTO@REGENT) here— we fly in ground effect, which is typically at altitudes less than 1/2 your wingspan. We fly, but low to help with aerodynamic efficiency and remain in the maritime domain.
