When we designed the orignal Sportfoil back in the early '70's, hydrofoils were actually more common than today. We started out with an experimental sailing hydrofoil, remarkably. Making a sailing hydrofoil is pretty tricky, and this very simple construction was only able to get on foil in certain conditions and couldn't tack, so we switched to a powered version: The Sportfoil was the result! Because this is such a lightly-loaded hydrofoil, we can use very small outboards (5-15hp.) and still have great performance. The America's Cup (which is on as we write this!) is showing the world just what sailing hydrofoils are capable of, in the most amazing and exciting ways! The Sportfoil is an older design, but is a good starting point to discover what it's like to fly a boat!
