Alado Nautica USA Roller Furling Sheaves

ALADO NAUTICA has self-contained double halyard sheaves to allow for fast sail changes and downwind sailing with twin genoas.

Existing sails can be used with simple adaptation.

The halyard is led through the sheave, returned and made fast to an eye on top of the drum.

Since there are no hanks, high halyard tension is not required and no halyard loads are applied to the mast.

No swivels are used. This eliminates the possibility of halyard warp, which can produce torque, leading to forstay parting and mast collapse.
