Harken Fly Block 18 mm narrow

Harken high-load Fly blocks were developed specifically for use with high-tech line. Efficient, and with an incredible working load for their small size, Fly blocks give sailors the power they need and are perfect for use on foiling dinghies and sportboats and for vang cascades and backstay systems on Grand-Prix racers. Their weight savings alone promises an instant uptick in racing performance. "The use of high-tech line with the current braid and cover technology allows Harken to design blocks with smaller sheaves," said Matt Schmidt, leader of the project. "Harken Fly blocks offer the same strength and efficiency as larger blocks, but come in a much smaller, low aero package." Sheave Ø (mm)18 mm Maximum line Ø (mm)5 mm Maximum working load (kg)125 kg
