If there is one trend that runs through boating across the board, it is foils. Powerboats, sailboats, catamarans, and even superyachts have all been influenced by this technology, which, while not entirely new, has received a great deal of attention and a large number of applications in the recent period, especially in the yachting world.

This year, we at Barche a Motore in collaboration with Suzuki Italia Marine have launched a podcast where we tell, on video, the basic concepts of how a boat works. It’s called I EXPLAIN THE BOAT TO YOU (if you haven’t seen it yet here is the link) and in the first episodes we started with the basics: hulls and types of boats. In the last episode, we tackled special and less common hulls such as catamarans and trimarans, to foiling boats.

What are foils and how they work

The foiling world is beginning to catch on: once in the air, the submerged surface area is minimal (about 3 percent compared to when the boat is stationary). Foils, the small submerged “wings,” have super-efficient, aircraft-derived profiles.

A modern invention? Actually an Italian, Enrico Forlanini, made his first “hydroplane” as early as 1910 on Lake Maggiore. Applications in the recreational world are often seen on small, lightweight hulls with electric propulsion. This is because the small displacement makes it easy to overcome the critical moment, i.e., entry into flight, which is also managed by thousands of self-adjustments per second of the foils, governed by electronics.

Foils, however, do not stop there. By now, superyachts are also using this technology to improve performance. A prime example is the Azimut Grande 44, the shipyard’s new flagship at 44 meters, will be the brand’s first hull with a foil system.
