Refined Design,Performance & Reliability
Ronstanís Continuous Line Furlers put great performance and reliability within the reach of cruising and racing sailors alike.

Advanced Drum Technology
The range matches drum diameters to load ratings providing the optimum balance between speed and ease of furling. Drums incorporate a machined groove profile and cross-hole geometry to grip the furling line securely. When deploying the sail the continuous furling line self-ejects from the grip zone, remaining stationary for smoother, safer operation with minimum rope wear. A PTFE perimeter strip ensures the unloaded furling line canít fall from the drum or become snagged.

Bearing system
Furlers and top swivels feature bearing sets that run on hardened races for smooth high load performance.

Easy continuous line installation and removal
The continuous furling line is easily fitted and removed from the furler, so it can be left on deck when the sail and furler are stowed below.
