The Jazz is Appletree's freestyle wing board but also makes a great light wind board in the bigger sizes.
Ultra-compact shape 
A shorter more compact shape means less swing weight resulting in quicker turns and easier rotations. We moved the wide point forward making it possible to still get the required volume in the board. Through the sizes, the length only increases by one inch, while the volume jumps up 10L, keeping the length short in the whole range.
Front foot recess standing area
A new and innovative feature of the Jazz is the recessed deck. This way we can keep the standing position at the right angle to the foil and at the same time we can add more rocker and volume to the front part of the board. 
The recess also provides an excellent and stable platform to stand. With the recess area running off into the tail we eliminate any water pooling in the deck.
Elongated planing surface
The bottom has a longer flat section around the foil connection. This vastly increases glide efficiency and improves low wind characteristics.  Especially in the higher volume sizes, the Jazz is a great lightwind board. 
The abrupt edge of the tail helps a lot with release which is very important when landing jumps, as you want that instant deflection off the water’s surface. The Jazz bounces back up like a skipping stone thrown across the water.
Soft frontal area
In the nose, the Jazz has an increased rocker, again to aid with deflecting of the surface. But the rails are also more rounded to further help eliminate sticking to the water. Moving down the board toward the tail the rails form an increasingly harder edge. This makes the Jazz feel really soft on landings.
