IFS™ Integrated Furling System

OneSails IFS™ Integrated Furling System
The next generation of furling sails.

OneSails introduceert IFS™ (Intergrated Furling System) een nieuwe technologie voor het oprollen van gennakers en code 0's. Doormiddel van onze doorlopende garen technologie kunnen deze zeilen worden opgerold zonder de dure en zware anti-torsie kabel.

IFS™ zeilen worden ontwerpen en uitgerust met doorlopende garens in het voorlijk van het zeil wat de anti-torsie kabel vervangt. Er zijn vele voordelen van het weg laten van de kabel, zo zijn er meer ontwerp en zeilvorm mogelijkheden en is het zeil makkelijker in gebruik door een lager gewicht.

The IFS™ is a new sail concept with important advantages noticeable both when racing and cruising.

  1. Verbeterde aerodynamische perfromance.
  2. Geïntegreerde structuur in het zeil wat het rollen zonder kabel mogelijk maakt.
  3. 35% minder val spanning.
  4. Zonder kabel is er meer vrijheid in het ontwerp wat de performance in diverse windhoeken bevorderd.
  5. Het zeil is makkelijker in gebruik omdat het lichter is en makkelijker in de zak te stoppen is.
  6. Stabieler achterlijk in de ORC en IRC regel.
  7. Zonder kabel is het zeil lichter.
  8. Afwerking en accessoires op maat gemaakt.

IFS™ Tips & Tricks

  1. The sail doesn’t need too much luff tension for proper effective furling, just tight enough to make it straight.
  2. The best furling is achieved when sailing dead downwind, reducing the apparent wind to a minimum.
  3. When furling, the sheet should not be completely eased, it is better to keep a slight tension on it, accompanying the furl.
  4. It is advisable to always furl the sail in the same direction, as the top will furl more smoothly and tightly.
  5. Before hoisting again, make sure the top hasn’t unfurled, which can happen during the dropping and stowage.
  6. Once the sail is unfurled, halyard tension can be adjusted according to the sailing angle (tighter for reaching, looser for wider angles).
  7. Although the sail doesn’t require a lot of halyard tension, the integrated IFSTM structure can withstand heavy loads so care should be taken not to over tighten the halyard in order to prevent damage to the furler and other fittings.
  8. The sail should not be left hoisted when furled with the apparent wind exceeding around 12 knots.
