This system was easily implemented in the Moth class. Since no existing design or class fit the ISAF specs, we decided to create an all-new design that is about 17 feet long, called the NACRA 17. It was fitted with curved daggerboards at the 2016 Olympic Games in Rio de Janeiro, to provide extra buoyancy and boost its efficiency both downwind and upwind.In response to recent developments and requirements, the next generation Nacra 17 Olympic has now been upgraded into. They move along just fine. The Nacra 17 fleet is 1 year away from our first Olympics as a foiling boat. The curve boards also give an added dimension to the sailing. The class is used within the SailGP series and is the first sailboat class to break 50.0 knots (57.5mph/92.6km/h) during a race, and is claimed that the top speed of the boat is 52.2 knots. When I look at the data files, most of my top speeds are only a length of 20-80 meters. The regatta is far from over with five teams scoring only top 10s on day one.

Then check out what Paul Kohlhoff and Alica Stuhlemmer (GER) pull out of the bag as they jump into hyperspeed. Many of the hydrofoils used in windfoiling can vary in size in order to obtain a greater combination of lift and top speed. Top Jibe VMG . So any current handicap is subject to revision in the very near future. Similarly to the 'C' and 'S' foils, the amount that the foil is lowered changes the amount of vertical and horizontal lift being created.[2]. You get the bow up and ease the sheet to keep from plowing into the back of waves.
