Manufacturing:

The mechanical parts of the Classic Profurl are machined by a controlled, patented process from extrusions of the purest metallurgical quality. Profurl is not manufactured from castings.

Adjustable Drum Height:

The standard long link plates (left) make access to anchors and ground tackle easier. This feature also enhances visibility forward, eliminates sail chafe by pulpits and lifelines, eliminates loading the sail with boarding seas, and allows easy turnbuckle inspection.

Fitting a Profurl with the optional turnbuckle cylinder (right) enables the drum to be mounted at deck level for maximum sail luff length.

Profurl Wrap Stop:

Profurl's patented wrap stop eliminates the chance of halyard wrap around the headstay, and prevents jamming of spinnaker or spare halyards.

Profurl Drum:

The Profurl drum is formed of an unbreakable, unscratchable, UV resistant high impact plastic. It is open for easy line inspection. Its slippery surface and patented conical flanges minimize any jamming potential. The strong stainless steel arms guard to keep the furling line on the drum should the line be slackened during sail deployment.

Profurl Couplings:

The solid, one-piece couplings are machined to lock in place thereby transmitting loads equally throughout the foil column.The plastics used for the bushings which isolate the extrusions from the stay contain graphite and molybdenum bisulpher. They are self lubricating.

Only Profurl's refined technology has been able to develop the use of carbon 100 C6 ball bearings. Classic Profurl's mechanisms are lubricated with a special grease, and permanently sealed.

Seals:

The double-lip seals above and below the bearings are specially made for Profurl of a high technology elastomer. Stainless steel clips embedded in the seals during molding provide perfect fit. Anti UV seals protect the double lip-seals.
