Advanced drum technology

The drum incorporates a sophisticated furling line groove profile and cross hole geometry to grip the furling line securely when furling. This is the same technology developed first by Ronstan for use in our world leading ratchet blocks to grip line gently but securely.

When deploying the flying sail the continuous furling line self-ejects from the grip zone, remaining stationary for smoother, safer operation with minimum rope wear.

Guide rollers minimise friction and rope wear on the furling line, and a floating PTFE perimeter strip ensures the unloaded furling line can’t fall from the drum or become snagged. The range matches drum diameters to load ratings for optimum performance. Smaller drum diameters allow faster furling and weight savings, while larger drum diameter options provide a greater mechanical advantage and easier furling.

Secure, snag free connections

Furlers and top swivels have retained quick release clevis pins and fairleads have a snag free, flush finish captive pin.

Maintenance free bearing system

Furlers and top swivels feature a factory sealed, maintenance free bearing. Hardened roller bearings and races provide smooth high load performance.

Material selection for strength and durability

Hard anodised grade 6061 T6 aluminium construction provides durability and corrosion protection. Grade 2205 stainless steel is utilised for the load bearing shaft for optimum strength to weight ratio.

Multiple attachment options

Attachment options include a high resistance shackle, trigger release snap shackle and fairlead, as well as a hard anodised aluminium thimbles designed specifically to suit anti-torsion luff line.

The furler drum can be set at either 0° or 90° attachment; as required to match the take-off alignment and deck layout.
