Lately the sport has been taking off!!! New technology concepts are being introduced Willie nilly.
The Z1, Neil Pryde's new race sail.
The shear tip reduces leech flutter and eliminates the need for cams at the top of the sail. The shear tip also reduces drag at the top of the sail and on the leech. The shear tip overall gives the sail improved acceleration.

North Sails has followed suit and developed the reactive head. This concept is the same as Neil Prydes 'shear tip', but the reactive head has been added to North's 3D sail, improving its bottom end and acceleration.
Flapper boards are cut off from the back foot strap, and a flap is attached underneath the tail of the board (hence the name). Although these boards are reduced in length they are still able to carry big sails. The concept is designed for course or slalom boards.
