C520 - Headsail manual furler - Max forestay dia: 16/19 mm

The C520 is a manual headsail furler from the Profurl Cruising range. It is designed for boats ranging from 16,50 to 18,50 meters with a maximum forestay diameter of 16 mm (#60 in rod). It features colorless anodized round extrusions. It comes with a 10-year warranty.

Profurl furling systems: the last word in reliability and longevity
Only Profurl technology offers optimal reliability and longevity. Profurl mechanisms are designed to use special bearings which can furl sails under any conditions. They are fully waterproof, protecting them from corrosion and contamination for maximum longevity.

High performance systems...
• The extrusions are made lighter and stronger thanks to a special alloy (6106).
• The ball bearings have an optimized weight / resistance ratio.
• The Wichard opening pre-feeder is delivered as standard on Racing models to hoist the sail faster.

Reliable and maintenance free
• The ball bearings are made of high strength 100 C6 carbon steel and are sealed in a grease bath to increase their working load and prevent corrosion.
• Watertightness is achieved by the use of two double lip seals preventing foreign bodies (salt, sand, dust, water) from entering the bearing mechanism.
• The not deformable plastic drums withstand impact (e.g: anchor bump, collision) and are resistant to UV.

Ease of use
PROFURL manual furling systems have been designed to ease operations:
• The standard feeder enables to easily hoist the sail by only one crew member.
• The optional opening pre-feeder, manufactured by Wichard, smoothly guides the sail’s luff tape into the extrusions, whilst rapidly hoisting the sail. When re-hoisting it, the pre-feeder can be reattached to the luff tape without removing the headsail from the extrusion.
Safety of use
• Double cage arms (exclusive to PROFURL) prevent the furling line from jumping off the drum and allow the furling line to re-align onto the drum by simply pulling on the line.
• Stainless steel locking devices are dedicated to boats with a closed to deck fitting.
• On the C480, C520, C530 and R480 models, special locking devices have been designed to withstand the higher loads. Reliability of materials
PROFURL rigorously selects the materials to be used for the manufacturing of the different components: these parts are submitted to bench-tests in order to assess their resistance.
• Ball bearings are made of high strength 100 C6 carbon steel.
• Drums are made of high impact plastic.
• Extrusions use a special alloy (6106) and offer one of the best weight / resistance ratios.
• The feeder and the opening pre-feeder are made of stainless steel (316L).

This product includes a drum, a complete set of grey rounded extrusions, a swivel. As a standard, it is delivered for a closed to the deck installation.
