North Sonar Aluminum Foil Mast & AF Board Adapter

North Sonar Foil Mast Size: *72cm in stock What North has to say about the Sonar Foil Mast: "Our new refined aluminum foil section gives the best balance between light weight and increased strength for higher loads. The AF72 Mast is 30% stiffer than the AK70 mast yet only 13% heavier, and is ideal for shallower waters, and prone surf foiling. The AF85 Mast is 30% stiffer than the AK85 mast yet only 13% heavier, and it increases overall ride performance in choppy conditions."
