Continuous line furling system: from ocean race to cruising:

In the past the continuous line furling systems used to be fitted on Gennaker furlers or Headsail structural furlers. Compared to a conventional drum, the advantages of a continuous line system are numerous: a bigger luff available, greater furling power due to a larger diameter drum, no risk of overriding. A technology directly developed in racing Gennaker furlers or "structural system" (structural furler, see page 10) fitted on Open 60's. Furthermore, this model can be fitted on existing Facnor reefing system (R range).
