In-Boom Furling Systems

Designed to reef or furl your mainsail, the PROFURL in-boom system provides safe reefing for your mainsail from the cockpit. The main halyard and the reefing line can also be operated from the cockpit. Hoisting the mainsail is made easy: just turn the boat into the wind, release the furling line and pull on the halyard. Reefing or furling is just as easy: simply control the tension on the halyard and pull the furling line. Profurl Boom FurlingThanks to a number of patented design features, controlling your mainsail is a smooth operation.

The only IN-BOOM system to boast the twin Gooseneck/Mast attachment system, which creates a much more stable and reliable junction, between the mast and boom.

Twin Goosneck Simple furling drum (patented)

Is located at the forward end of the boom (patented), requiring only one block at the mast foot to lead the furling line towards the cockpit: less blocks means less friction.
Boom section

Open boom section: allows easy fitting of the sail, avoids friction on the edges - a disadvantage of other systems with semi-closed boom profiles, allows the sail to be inspected from the deck to ensure correct furling, and allows access to the main mechanical components.
Luff Extrusions Luff extrusions (patented)

Are articulated behind the mast. The bottom end of the luff extrusion is connected to the top of the boom, allowing it to rotate with the boom. Whatever the angle of the boom with the boat, the sail and the luff extrusions are always in perfect alignment, this dramatically reduces luff tape friction and wear.
Transferring the sail from the luff extrusion into the boom (reefing or furling), or from the boom into the luff extrusions (hoisting) is much easier than with other systems. This device is unique because it does not require the boat to be head to wind before operating the system.
Feeder (patented)

Includes two large size bronze rollers which protect the luff tape at all times.
The feeder allows for :
accurate adjustment of the distance between the two rollers to suit every thickness, or type of luff tape,
quick adjustment of the rollers for feeding the sail into the luff grooves,
bronze rollers automatically return to the adjusted roller width.
 
Sheave box on mast Sheave box (patented)

The original halyard is normally used providing it is long enough to reach the cockpit. PROFURL has developed a special upper sheave box which allows the halyard to exit the original masthead and leads it to the rear side of the luff extrusions. When the luff extrusions turn in line with the boom, the design of the sheave box allows the short length of halyard between the mast head and the sheave box to be in alignment, again avoiding friction and chafe on the mast head cheeks.
  Rigid boom vang (patented)

Is standard with the system. It has been specially developed by PROFURL because the mast-boom angle is absolutely essential to the smooth furling of the sail. As soon as the mainsheet is released, the PROFURL boom vang automatically repositions the boom upwards to the correct reefing angle.
The PROFURL boom vang is compressed when using the mainsheet to tension the leech of the mainsail.
