Mainsail

 

We produce three different shapes with different cloth types and panel layout configurations.  Each design has been proven on the race course and has been used by top competitors including the 2007 World Champions.

 

M6 Design

 

2nd Place -

2008 World Championship, New Zealand
Oskar Johansson and Kevin Stittle (Canada)

2nd Place -

2007 World Championship, Portugal
Carolijn Brouwer & Sebastien Godefroid (Belgium)

 

This is a cross-cut construction sail made out of Dimension FLX13P with horizontal panels. The batten pockets run along the seams which are ultrasonic bonded (making the joints stronger than the cloth itself).

 

This model is ideal for the widest wind ranges and has proven to be the most batten sensible mainsail. The shape was designed with SMSW6 design software and was first tested introduced in 2005.

 

PLR4 & CC4 Designs

 

1st Place -

2007 World Championship, Cascais, Portugal
Fernando Echavarri & Anton Paz (Spain) with PLR4

4th Place -

2008 World Championship, Takapuna, New Zealand
Roland Gaebler & Gunnar Struckman (Germany)

7th Place -

2008 World Championship, Takapuna, New Zealand
Fernando Echavarri & Anton Paz (Spain)

 

Both sails have the same shape, but are vary in their construction.  The PLR4 is a radial mainsail built out of Contender Apen, while the CC4 model is a cross-cut mainsail built out of Dimension FLX13P cloth.

 

This design is a very powerful sail ideal for a specific wind range when both crews are on the wire up to 19/20 knots of breeze.  The sail becomes too round in less than 8 knots and too powerful over 22 knots.

 

We have recently produced an updated, alternative version of each design – known as the PLR5 and CC5 – with a different luff curve that makes the sail better in a larger wind range plus ideal for lighter crews.

 

TM51717 Design

 

Our newest development, this design is some major differences in the draft wing position, twist numbers and mast bend data. This shape has proven excellent, particularly in very light to medium conditions. We can produced this design in a number of different cloth types.


 

Jib

 

We produce three different jibs, all with the same window material variables:

 

LP29
AP7-P9
AP7-M10

 

LP29 design

The LP29 design is the flattest jib we build.

 

AP7-P9 and AP7-M10

These two designs are different in the top part of the sails where the AP7-M10 has a straighter exit AP7-P9.

 

Mostly of our jibs are produced using Dimension PE15-1.5mil with front luff pane in PE110-1.5mil. Often we do them all in PE10-1.5 mil and different windows done from standard Dimension T725-4 mil to crazy light material.

Spinnakers

 

The fastest proven design is the HNDY9 which won the 2007 World Championships. We have changed the name although the panel layout and construction are the same. We primarily produce this spinnaker in Contender nylon superkote80, although it can be produced in other cloths including polyester or Formulon50 for light conditions.
Every spinnaker is delivered with patches and is coated in Holmenkol product to make the sail slippery.


 

Cloth Options

 

Choosing the best cloth is a constant topic of discussion amongst Tornado competitors.  After years of research and testing, we have compiled a list of different cloth properties.
