Foiling is maximum freedom for 3 reasons.
1) Go where ever you want very quickly. It is twice as easy to track upwind and downwind on foil than when on rail. While riding you can average 18mph and even faster on more efficient foils.
2) Maximize your riding time. I have kited twice as much in and out of season than I did before I owned a foilboard.This is because the foils are so efficient that you can ride in as low as 8 knots.
3) Ride longer without the chatter you get in choppy conditions. When you are on plane, you hover over the chop. This makes the ride smooth and zen-like.
