What sail to have Fun on a step-tail longboard?

What should you look for when selecting a sail for your KONA Style or ONE, or some other longboard with a freeride bias?

One-Design Racing
- Then it is pretty much a done deal. You get  a class legal one design sail (in case of KONA it is the KONA OD sail, in 5.8, 7.4 or 9.0 m2) in the size that is relevant for your body weight.

General racer criteria
- Performance oriented sail. There is no reason to omit cambers.
- Ease of rigging not relevant as the racer knows what to do
- Trimming the sail is allowed to be difficult and require expertise
- We can see for example from the raceboard class that there are no RAF sails, just cambered ones.
-In the windsurfing sail industry there is now one trend that emphasizes power per square meter. Virtually all of these sails (Severne, Sailloft, North) are set up with a few cambers to create a deep profile already before there is any wind pressure. This kind of sail ought to be a good match for the KONA.

Recreational criteria
- It should be a versatile sail. It should have a huge windrange in one setting (that should be easy and intuitive to set). And it should be competitve in racing situations with cambered sails (and preferrably be responsive to outhaul trim).
- Should be simple and straight forward to rig and to trim. The sail should have with a lot of built in static camber (i.e. at rest) in order to drive well also in very light wind. Note that most camless sail go virtually flat without windpressure, these sails are good for planing windsurfing, and for freestyle, but not for light wind cruising.
- It is a definitive advantage if the sail has no cambers. A longboard recreational sail should enable freestyle and messing around (i.e. it should NOT have cambers).
- The concept of a soft feeling sail with a tight leach is great for this purpose. The sail should have lots of skin tension for a tight lower leach, and it should have a mast pocket with lots of excess cloth to give softness and feel.
- For recreational use it is VERY important that the sail pumps well (effectively)! For recreational use it is VERY important that the sail is effective (has positive drive) at the planing threshold.
- A tight leach sail with a lot of camber is more effective in light wind. A high tension sail with good twist is better in high winds. The sail must combine these two characteristics.

Retro and KONA

A way of looking at what types of sail the market would have selected (if given the choise) is to check out what sails have been registered for the Bic Techno 293 class (see " http://www.techno293.org/page0014v01.htm"). Another way is to take a look at the Sailworks Retro (picture) that is pretty much everything a longboard sail should be.
