Ronstan 120 Series Manual

Furler System Information
The furler you have purchased is designed for the furling of sails with a "straight" luff, such as code zero sails,
screechers or staysails. These sails are generally for sailing at true wind angles less than 90°. The furler is
designed to have the tack of the sail attached to the furler and the head of the sail attached to the top swivel.
This will provide furling along the whole luff of the sail.
The sail must be either completely unfurled or completely furled – the furler cannot be used with a partially
furled sail.
You will require a synthetic luff cable (torsion line) with a thimble at each end, connected between the fork of
the furler at the bottom and the swivel at the top. We recommend you discuss options with your sail maker for
torsion line type, diameter and length, to suit your requirements.
Ronstan provides a range of accessories to suit this furler which can be found at the end of this manual.
