Structural furlers have been installed on racing sailboat for a long time. They are light and support mast loads. This high performance system is also fitted on ocean cruising yachts for headsails (Jib, Staysail). Available from 40′ in classic or endless line drum design.

THE STK BENEFITS:

  Gain in weight (around 3 times lighter than a traditional furling system)
  High torque power (due to the large diameter of the low profile drum)
  Maximized luff
  Simple installation. Different terminals
  Resistant and tested under high load
  Possibility to tight up the luff thanks to a 2-to-1 block fitted under the drum
Available  in classic or endless line drum design, various terminals from toggle to screwed connection with the forestay

Numerous possible configurations (top and bottom)

HYDRAULIC STRUCTURAL FURLERS:

Facnor has been developing hydraulic models to the assistance needs on board maxi yachts.

> Compact & reliable

> Adaptable according to needs: many possible terminals
