Formula 18 Sails

The Catamaran class we and most cat sailors are most passionate about

Sven has been sailing in the Formula 18 class since its inception. The class stands out for its combination of tactical racing and the thrill of speed. Formula 18 sailing requires not just racing skills but also the ability to choose the right equipment for your sailing style. Kangaroo Sails has a long-standing philosophy of making sails that are user-friendly. We believe that a sailor should be able to concentrate on the racecourse, competitors, and wind conditions, without being bogged down by sails that are difficult to handle. Our sails are designed to make a sailor’s life easier.

we found that a single sail shape for a variety of sailors is too much of a compromise on performance so with 3.0 there are two shapes with different depth



  • For traditional non-Decksweeper sails
  • shorter foot
  • more twist


  • For Decksweeper Mainsail
  • Long foot to optimize airflow around the DS
  • reduced twist for more height


  • non Decksweeper traditional F18 Mainsail
  • easy to cross over


  • our Recommendation for Racing
  • reduces turbulent air around the foot of the sail
  • narrower Top to bring the center of effort further down
  • very long DS – only the helmsman can cross behind
  • our Decksweeper is the only sail that always touches the Deck (in simulations this has proven vital in order to keep the pressure difference as long as possible)

High Tech:

  • Fiberfoam Carbon batten
  • better shape control

We prefer the High Tech version, which provides better shape control with its Fiberfoam Carbon battens. However, this option is stiffer and heavier. The clean exit of the jib to the mainsail is favored, but there is an increase in weight.
