Candela flying #ferries to bring #commuters back #boats
Over 17kts she lifts above the water & then we fly at around 25kts
The 30-seat vessel rises smoothly above the surface, lifted by #hydrofoils controlled by onboard #computers
“When we lift the #boat, the drag from the water reduces 80 to 85 percent,” says the captain. “And we can charge this boat fully in approximately one hour.”

on that topic of #flying 🛸🚤
"Like F1 cars with airfoils, a boat can have hydrofoils - wings curved up top and flatter underneath, so when they move through a fluid the pressure reduces on top and increases underneath, producing lift.
Traditional hydrofoils make for a bumpy ride, but put underwater the speed gains are huge while the ride stays smooth, smooth enough to create nearly no wake.
Right now most waterways near cities are no-wake zones, so powered boats have to go slow. That leaves waterways underused, e.g. compared to roads. Underwater hydrofoiling could change that, plus also make the boat quieter, and cut energy usage by up to 80%. First hydrofoil #ferries are currently running in #Sweden."

Aside from #paralympics I've been watching a bit of the most posh sport: #AmericasCup qualification, i.e. sailing with really really really expensive boats.
What I love is that they are using #hydrofoils. I've seen these experimented with in human-powered boats >20 years ago (I've ridden 3 hydrofoil boats then, all muscle-powered) and now there's these big yachts but also hydrofoil kitesurfing and windsurfing.
Fascinatingly efficient and fast!
