This boat’s performance comes, in part, from under the water in the form of foils. Not the foils most people think of, where the boat is raised above the sea, sitting on blades that look like skis. Instead, the R35 has what’s called the Princess Active Foil System. Picture two T-shaped wings tucked into the hull, forward of the sterndrives. When the foils are deployed, they don’t lift the boat up, but instead constantly adjust the R35 for heel and running attitude, ensuring stability. Princess says the foils also reduce hydrodynamic drag by up to 30 percent, increasing overall performance and that slick feeling underway.
