The Magic of Foiling

A Complete History and Why It’s Exploding in the San Francisco Bay Area

Hey everyone, it’s John from KiteTheBay. If you’ve seen riders silently gliding above the water near Crissy Field or the Berkeley Marina with almost no splash, you’ve witnessed the incredible world of foiling. Whether it’s kite foiling or the fast-growing wingfoiling, this sensation of flying over the water is addictive — and it’s one of the best reasons to book foiling lessons right here in the San Francisco Bay.

Here’s how foiling went from a niche experiment to one of the most exciting disciplines in watersports.

The Early History of Hydrofoiling

The concept of hydrofoiling dates back over 100 years. In the late 1800s and early 1900s, inventors like Enrico Forlanini and Alexander Graham Bell experimented with wing-shaped structures on boats to lift the hull out of the water and reduce drag. The goal was simple: go faster with less power.

Fast forward to the 1990s and early 2000s — pioneers like Laird Hamilton and others started attaching hydrofoils to surfboards. Suddenly, riders could glide smoothly across ocean swells with far less wave energy needed. This “foilsurfing” opened the door for wind-powered foiling.

How Foiling Took Over Kite Surfing and Created Wingfoiling

Kiteboarders were quick to adopt foils. By the early 2010s, riders realized that pairing a kite with a hydrofoil board allowed them to ride in much lighter winds and go upwind with incredible efficiency. Kite foiling exploded in popularity because it turned average days into magic sessions.

Not long after, wingfoiling was born. Early experiments with handheld wings happened in the 1980s, but the modern sport took off around 2018–2019 thanks to innovators like Robby Naish, Tony Logosz, and others who developed inflatable wings. Wingfoiling combines the freedom of a handheld wing with the silent glide of a foil — no kite lines, just pure connection to the wind and water.

Today, both kite foiling and wingfoiling are mainstream. Formula Kite (kite foiling) even made its Olympic debut at the Paris 2024 Games, shining a global spotlight on the discipline.

The Physics Behind the Magic: How Foils Actually Work

At its core, a hydrofoil works like an underwater airplane wing. Here’s the simple physics that makes it feel like flying:

• Lift: As the foil moves through water, its curved shape creates higher pressure underneath and lower pressure on top — generating upward lift (just like an airplane wing in air).

• Reduced Drag: Once the board lifts out of the water, drag drops dramatically. That’s why you can glide at higher speeds with less power from the kite or wing.

• Speed & Efficiency: The faster you go, the more lift the foil produces. This creates a beautiful feedback loop until you’re flying smoothly above the chop.

Technical Aspects to Know:

• Most foils have a front wing (for lift), rear stabilizer (for control), and a mast that connects to the board.

• High-aspect foils are efficient and great for lighter winds and upwind riding — perfect for the San Francisco Bay.

• Low-aspect foils feel more playful and forgiving for beginners learning to fly.

• Materials like carbon fiber keep them light and strong.

The result? Silent, low-impact riding that feels almost effortless once you’re up.
