This is a really interesting topic that I know little about. This paper was published 36 years ago—is it still current with modern understanding of sailing? Or has anything changed or been refined significantly since?

In the last couple decades, there's been a lot of innovation with hydrofoiling, which significantly minimize friction between the hull and water.

The America's Cup AC35s [1] and Flying Moth Class Dinghies [2] can achieve incredible speeds thanks to being elevated out of the water.
