And discussing how they are not getting as much WIG effect for that, but still significant savings (Vs what, an airplane? How does that compare versus other marine transport?)
> The benefit of ground effects are: - 10-20% range extension (agreed, between 50% and 100% wingspan, which is where seagliders fly, the aerodynamic benefit of ground effect is reduced compared to near surface flight)https://news.ycombinator.com/item?id=36053471
