‌ BACKHAND POWER CONTROL 2.0

For the 4Wave LTD we could radically improve the backhand power control concept that originates from our 4Wave and 5Wave sails.
On the LTD we have more agility, more release but the same mighty low-end the 4Wave is known for. By defining the profile of the sail with a special mix of materials (instead of pre-profile built into the sail) we can control the twist of the sail body in a unique way that offers you that little bit of extra horsepower – available whenever you need it. The total wind range of the LTD has been extended significantly with improved high-end control.

 ADAPTIVE WIND RELEASE  (AWR)

The brand new AWR system takes the backhand power control approach to the next level. By opening the AWR you allow the sail to release the wind more efficiently. The power draft moves forward slightly, offering a more agile, more playful and more forgiving ride while maintaining the same early planing ability. If you like a radical surf-like feeling the open setting is for you!

The closed AWR system creates a more locked-in powerful sensation with extra backhand power. This setup increases the sail’s top leverage and provides added traction to the board on large bumpy waves, fully powered conditions like Pozo or when using it in flat water high-wind sailing. If you seek maximum power for big moves, competitive sailing and bump-and-jump try closing the AWR.

Changing the AWR is different to changing the downhaul: Keeping a baggy sail while changing the loose leech release behaviour?! Now you can!! We tested the AWR extensively in the most hardcore big-wave conditions in Australia to ensure maximum strength and long-term durability.

‌ AEROFIT BOOM POSITIONING (ABP)

This unique and brand new feature eliminates all downsides of a traditional boom opening. By reducing the open area at the leading edge of the sail we have improved the aerodynamic efficiency of the sail. This results in a wider total range of use. The second effect of the ABP is the limited range of movement of the sail body in the boom area. The sail will be more stable in the gusts and will react much quicker in any rotations.

HOW TO USE: Always open a minimum of two sections to mount your boom. This gives the flexibility to play with your boom height in case the conditions are changing. If you expect to share your sail with a taller or smaller rider during one session simply open more sections while rigging the LTD.

 POWER PANEL DESIGN

Key to the LTD's outstanding efficiency is the wide outline in the centre of the sail while keeping a relatively short boom. The panel above the boom gets the cleanest airflow. That’s why we like to call it the “power panel”. It creates this sail’s controlled drive and power while the narrow top guarantees a perfect and smooth clew-first behaviour.
This sail's mighty low-end acceleration will easily outperform bigger sails, so for the full experience make sure to ride your 4Wave LTD 0.2 - 0.5 sqm smaller than you usually would! With one pull of the backhand you can always unleash the power while you benefit from faster rotations and more radical turns on a smaller and lighter sail and last but not least a much better wipeout-resistance of a smaller sail in big surf. When you can ride a 4.8 in 5.0/5.3 conditions imagine the crazy handling advantages of a 4.8 compared to bigger rigs!

‌ FREEFLOW BATTENS

We have carefully adjusted the batten angles to improve the release in top turns and big jumps. This allows the loose leech to work more efficiently. The LTD feels lighter and more reactive than the original 4Wave now. A new stiffer batten construction above the boom locks the power in more forward and extends the wind range significantly in difficult and gusty conditions as the sail's trailing edge is more flat and creates less drag. By reducing the width of the batten pockets by 10mm we locked the battens in place and saved a few more grams on the sail body.
