The Giant features 3 square meters of sail area, aircraft grade aluminum tubing mast, furling device, three pulleys, main and furling sheets, furling cleat, and storage/transport bag.  Fantastic for those who are wanting to extend their kayak range or just go have some leisurely fun on the water!  The mast is 7/8" diameter (23mm) at the base and fits without modification into the Hobie Mirage Kayaks mast receiver. Other kayaks require a mast mount.
