The Hydrofurl 200 has a 120 mm mechanical length adjustment, which alters the pin to pin length of the stay rather than the height of the tack boat swivel above deck.

The tack swivel allows the furling section to rotate through 90 degrees before starting to rotate. This reduces drag of the sail at the feeder while also permitting an optimal sail shape.

Suitable for:

- Rod 40, 48, 60 and 76
- Wire diameters 14, 16 and 19 mm.

Two types of furling section, E and F, fit the unit depending on the size of the stay.
