MANUAL REEFING SYSTEMS > Safety of use > > The 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. > The stainless steel locking devices are dedicated to boats subject to intensive use (blue water cruising, charter, pivoting marine catamaran masts, old gaffers) > 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.
> The ball bearings are made of high strength 100 C6 carbon steel.
> The drums are made of high impact plastic used in the car industry.
> The extrusions use a special alloy (6106). > The feeder and the opening pre-feeder are made of stainless steel (316L), except C290. > The benefits of the PROFURL systems > > A wide range of reeng systems for cruising and racing.> Cruising systems for boats from 5 to 26 m with round silver anodized extrusion.
> Racing models for boats from 6 to 20 m with black aerofoil anodized extrusion.
> One forestay diameter for one furling system.
> The ability to use an existing forestay (in most cases).
> Several tting options: standard, long link plates, with turnbuckle cylinder, below deck.
> Light and robust extrusions. > Maintenance free ball bearings.
> Insulation of the different materials.
> 10 year world wide limited warranty. 9
