WINDYAK kit for sea kayaks.

WINDYAK concept applied to existing sea kayaks : keep easiness and use of your kayak, and take advantage of wind !

A la pagaie / Paddling barrant avec la pagaie / Steering with the paddle

Designed for a fully decked kayak with manhole. Kit is easily plugged on a kayak, without modification, by simply bolting a central module supporting beam and rig to existing standard inserts of the boat (central module interface points are specific to each kayak model).

Beam is transported fully assembled with its folded floats, for a very quick mounting/dismounting.

The beam rotates to the fore for unfolding, paddle is used as a rudder like on viking boats.
