The Lun design had several drawbacks. One was that although the ground effect enabled it to fly at low altitude, in order to utilize the effect it had to fly as low as 1.5–3.0 m (5–10 ft) off the water due to its short wingspan, so it could not fly when seas were even mildly rough. Another was that the craft was only designed to use the ground effect principle, so it could not ascend to higher cruising altitudes.
I question how on earth this got past the whiteboard phase. If seafaring ability was the need, why not build this as a ship? If speed was necessary, why wasn’t this a true aircraft?
Given similar hull size and power, and depending on its specific design, the lower lift-induced drag of a GEV, as compared to an aircraft of similar capacity, will improve its fuel efficiency and, up to a point, its speed. GEVs are also much faster than surface vessels of similar power, because they avoid drag from the water.

Majestic. Imagine freaking out first time seeing one of those back in the seventies.
