[Yo-Yo]

Normally ground effect is roughly 10% of the wingspan, so the height will vary with wing length.

Also, notice the placement of the jet engines. The wing is a 'blown' surface (I see you smirking, Bevis) and as such increases the wing lift which will also increase the ground effect working height.

However, like someone already said, a rogue wave would not make for a good day.

"Heh heh, he said 'blown!'"
