There’s a type of boat called a hydrofoil that has actually been around for over 100 yrs. The secret lies underneath the hull, where there are basically underwater wings. Once the boat reaches enough speed, it actually lifts out of the water and “flies” with only those wings in the water. Hydrofoils are used all over the world. Our military built some, and they were especially useful in chasing down drug runners. A boat hull creates drag when it’s in the water. Once the hull lifts out of the water, it can travel 4X faster. It’s a simple principle – the shallower it runs, the faster it can go. Sound familiar?

In order to go faster, we get shallower – superficial.
