The IQ is our 4 batten wave sail. This concept was introduced a few years ago for the new school wave sailing style and for the new multifin wave boards. This kind of sail is more compact and more radical in the maneuvers. The new school style of sailing wants to stay closer to the steep and hollow part of the wave and this is what the IQ is designed for. But that does not mean that the IQ is only good in radical and perfect conditions, it still has enough power and stability for being used in less than ideal conditions. For 2013 all sizes are 4 battens and we introduced a new 5.4 size.
