Sonar HA1050 Front Wing 2023Description Engineered for the highest speed and efficiency possible, the HA1050 is one of our core wing foiling and prone surf sizes. With less surface area and a higher stall speed, the HA1050 is designed to generate maximum efficiency with minimum drag, also making it an ideal choice for high speed wing foiling and kite foiling. The wingtip is designed for zero ventilation when you tip breach, allowing you to crank faster, tighter radius turns.
