BOOM TECHNOLOGY

nsw_ws_tech_since_logo_1.pngTHE TRUE.RIG.BRAND

In addition to sails almost every other brand today also offers masts, booms and accessories. These invariable items are called OEM products that are easily purchased at either of the two Asian producers. That's why their products are so similar: a color change here, a new print there and
done. This way development or even innovation is out of the question. This is a real shame! Specifically designed components offer so much development potential - not only in terms of comfort, but as well in performance and durability. We already recognized this over 30 years ago back when we were the first sail brand developing our own booms. We are still shaping the future of windsurfing and promoting the sport so together with the team our engineers and technicians spend a tremendous time on the rig components. With some amazing results.
 

 


 

iFRONT 2.0ifrontwaage.jpg

The lightest front-end on earth!

 

The technical masterpiece which makes all NorthSails booms even more functional: iFRONT 2.0 the latest front-end of the next generation.

The STREAMLINER.DESIGN has aerodynamic as well as weight-oriented advantages. It doesn’t just look slimmer and smoother, the iFRONT 2.0 is also a whopping 35% lighter than its predecessor! With 345 grams it is the lightest front-end on the market!

90% of all other booms on the market are equipped with the same front-end from China, which usually differs only in color or design details. Especially in major components we at NorthSails are investing heavily in research and development to be far ahead of the competition. A prime example of this is the completely redesigned and absolutely unique iFRONT 2.0 front-end; it combines maximum ease of use with highest functionality, lowest weight and guaranteed durability.

 

Currently, two different front-end systems are offered on the market:

1 The performance-oriented design (NeilPryde, NorthSails iFRONT 1.0). These are uncompromisingly rigid front-ends in ALL directions, offering maximum vertical (torsional) stiffness. This leads to an extremely direct connection / transmission of boom to mast (= maximum performance). Whilst this construction offers no horizontal flex which is where the performance aspects come into play the adaptation to different mast diameters is possible only via a V-geometry of the collar. This can lead to point loading of the mast, which increases the risk of slipping and also mast breakage.

2 The "cuddly" construction (Aeron and all OEM versions that are used on 90% of all booms). This front-end flexes in ALL directions and the soft sidewalls of the collar adapt to any mast diameter. This protects the mast and avoids slippage. The disadvantage is that the soft sidewalls offer just a very low vertical (torsional) stiffness = low performance.

 

15_ifront2_combined2.jpgFor the first time the construction of the iFRONT 2.0 combines the advantages of both concepts in one front-end:

A Vertical stiffness: Unlike other front-ends we use 50% longer stainless steel axle-bolts which are directly connected to the side walls. Thus we obtain a maximum vertical/torsion stiffness, which results in an extremely direct connection/transmission of boom to mast (= maximum performance).

B Horizontal flexibility: The partially recessed center of the collar gives the iFRONT 2.0 a kind of hinge function, so that the collar fits to any mast diameter without any gap (= very smooth on the mast and extremely slip resistant). We know of no other front-end that fits so smoothly around the mast and thus effectively protects the mast.

This exceptional fit is guaranteed on SDM as well as RDM masts as the iFRONT 2.0 can easily be adapted through the exchange of 2 different friction pads.

  

It is an open secret that different conditions require front-ends with different vertical/torsional stiffness so that the rig can develop its maximum potential yet the comfort doesn’t suffer. For this reason, we deliver the new iFRONT 2.0 in two different stiffness options that are tailored to the individual disciplines and requirements:

- Stiffness I with 15% vertical flexibility has a very low flex for direct power transmission yet maximum control and comes with all RED, SILVER, as well as GOLD and PLATINUM (up to 170) booms. 

- Stiffness III with 0% vertical flexibility for uncompromizing torsion-stiffness and maximum performance on large sails comes with all GOLD and PLATINUM (190 and up) booms.

 

Of course, we remain true to our promise of long-term compatibility even with the iFRONT 2.0. Therefore it is 100% retro-compatible with older NorthSails booms that can be upgraded and tuned.

 PROTECTION.GRIP-INSERT 

(PLATINUM, GOLD, SILVER HD)

More resistant

The high-density EVA grip insert at the outside guarantes maximum abrasion resistance during rigging.

 

 

 

 

 

 

 


 

14_boom_feature_wide_tail_2.jpgWIDE.WAVE-TAIL.GEOMETRY 

(PLATINUM, GOLD and SILVER HD up to 160)

Equal load on both hands and improved handling

Also the short booms now feature a 4 cm wider tail-end moving your back-hand further away from the sail. For the first time now your back- and front-hand are equally angled making sailing less fatigue. You immediately realize this much more relaxed sailing position no matter if going in a straight line or down the line on a wave. The second advantage is a much improved handling during ducking maneuvers.

 

 

 

 

 


 

EXTERNAL.TAIL-FITTINGS

(all booms)

Minimum weight and unmatched features

        Especially on carbon booms most brands integrate the fittings into the tail-end to generate a clean look. 

        We prefer external fittings and achieve 2 crucial advantages:

        1. Much lower weight

        2. Features and functions which no other brand can offer (see iTAIL.RACE.FITTING and iTAIL.WAVE.FITTING)

14_boom_feature_3.jpgiTAIL.RACE.FITTING

(PLATINUM and GOLD 170 and up)

Rigging without threading - even when using an adjustable outhaul-system

The ultimate highlight is the all new iTAIL.RACE fitting. The teflon-POM synthetics build rollers feature a minimum of friction. Additionally, this unique solution allows to loop the rope even when using an adjustable outhaul-kit!

 

 

 

 


 

iTAIL.WAVE.FITTING 14_boom_feature_4c.jpg

(all SILVER HD plus PLATINUM and GOLD up to 160)

Frictionless alignment plus excess rope storage

The iTAIL.WAVE fitting offers 2 revolutionary details: 

A The patented LOOP.LOOP.GO 2.0 function guarantees an ideal 100% frictionless alignment of the rope!

B Instead of tying the excess rope around the tube you just wrap it around the integrated "bridge" at the bottom side - the cleanest and fastest solution ever!

14_boom_feature7.jpgOUTSIDE.TAIL

(PLATINUM and GOLD 170 and up)

For 20% increased stiffness of the boom

All PLATINUM RACE SERIES and GOLD RS booms feature the individual OUTSIDE.TAIL-END with an increased diameter. The high cross-section makes the boom 20% stiffer.

(PLATINUM and GOLD up to 160)

The ultimate tail-end grip

The EVA-gripped tail-end guarantees anti-slip. A reduced diameter of the inside tail-end additionally increases grip-comfort up to a maximum.
