SLS stands for Strong Light Superior and is your gear that empowers you to push your limits and strive for peak performance without compromise.

IMAGINE A BOOM WHICH IS VIRTUALLY INDESTRUCTIBLE EVEN AFTER YEARS OF USE AND THAT ALLOWS FOR LONGER SESSIONS ON THE WATER, SPEEDS UP YOUR RIGGING, ALLOWS YOU TO COVER ALL YOUR SAILS WITH JUST ONE BOOM AND IS LIGHTER YET AT THE SAME TIME STIFFER THAN ANYTHING YOU HAVE EVER EXPERIENCED. A MISSION IMPOSSIBLE, ONE MIGHT SAY AS SOME OF THESE TARGETS ARE EVEN CONTRADICTORY.

For us this dream started in 1997 with the first carbon boom we have ever built. And now almost 3 decades later we have the feeling that we have finally achieved all of these goals with the latest PLATINUM SLS boom range. We consider these booms to be the final evolutionary stage in the development of carbon booms.

With nearly 3 decades of Maui development and Munich engineering DUOTONE has the greatest experience in carbon booms in the industry.

The new PLATINUM SLS lineup underlines this by being the most feature-packed carbon booms out there. The goal was to create the highest performing booms combined with the best ergonomics, unmatched stiffness and fastest operation. Here comes a rundown of these feature monsters:

FULL CUSTOM CONSTRUCTION We use 100% highest-grade T800 prepreg carbon and our exclusive SENTEX® resin impregnated with silicon nano-spheres.

SEGMENTED CROSS-SECTION TECHNOLOGY This results in a quantum leap in weight >< stiffness >< durability >< grip-ergonomics/comfort With weights between 1.85 to 3.10 kg (depending on the length) the PLATINUM SLS are the lightest booms on the market (except our own PLATINUM AERO booms :-) The secret of these super-light weights lays in the SEGMENTED CROSS-SECTION TECHNOLOGY. Instead of the usual round cross section the PLATINUM SLS feature a super sophisticated transition of different cross sections:

  • The SQUARE FRONT SECTION featuring a massive wall-thickness increases the stiffness by approx. 30%
  • The OVAL TAIL SECTION increases the lateral stiffness by another 30%

This results in the new PLATINUM SLS not just been the lightest but also stiffest booms out there. Another advantage of the OVAL TAIL SECTION is the reduced tail weight. Due to the leverage effect this has a tremendous effect on how light the PLATINUM SLS feels in your hands (= sailing weight). 

GRIPPING DIAMETER: GRIP COMFORT VS. STIFFNESS With the diameter in the gripping area you are dealing with 2 contradictory facts:

  • The thinner the diameter, the more comfortable and less tiring it is to hold on to 
  • The thinner the diameter the softer the boom becomes

The enormous stiffness generated in the front and back allowed to use smaller diameters than any other boom in the gripping area. Together with the OVAL INSIDE GRIP SECTION this leads to an unmatched gripping comfort and reduced fatigue - sail longer and no more cramped fore-arms!

60 CM EXTENSION RANGE ON ALL BOOMS

  • Just 1 boom to cover all your Wave sails
  • Just 1 boom to cover all your Freemove sails
  • Just 2 booms covering all racing disciplines and sizes

DISCIPLINE SPECIFIC BEND-CURVES All our bend-curves are designed to allow your front and back arm to sit in a natural ergonomic position while sailing. This position varies with the type of sail (Wave >< Freeride >< Race) so each boom size needs to be developed accordingly.

  • The 140 Mega Slim and 160 lengths have received a completely new bend curve called NEW SCHOOL 2.0. For the first time it combines the advantages of a straight new school curve (no overstretching of the front hand) and a performance oriented curve (wider distance of the tubes in the center to avoid the sail profile from getting distorted). 
  • For the 170 and 190, we use the same tried-and-tested race curves that have proven themselves in countless race victories over the last decade.

iFRONT 2.0 The lightest moulded front-end on earth

PROTECTION GRIP INSERT High density EVA grip inserts on the outside front arch for maximum abrasion resistance during rigging 

EXTERNAL TAIL FITTINGS External tail fittings provide 3 main advantages compared to integrated fittings:

  1. Lower weight
  2. Stronger tail end. No weak points in the mould
  3. Exchangeable 

INDIVIDUAL TAIL FITTINGS 

  • The sizes 140 and 160 come with our patented VTS TAIL fitting which visually indicates the correct outhaul tension (DUOTONE sail required)
  • The sizes 170 and 190 come with the iTAIL RACE fitting which allows loop-loop-go (the fastest way to rig your outhaul) even when used with an adjustable outhaul system

TRIANGLE BEARING CONSTRUCTION Bearings in-between the rotational front-end and the monocoque carbon body prevent the front-end from „grinding down“ the carbon which ultimately leads to a broken boom.

2 YEAR UNCONDITIONAL WARRANTY We are fully convinced that the PLATINUM SLS booms are virtually indestructible. As a prove of testimony we back this up with our unmatched 2 YEAR UNCONDITIONAL WARRANTY. 


Now is it worth it? Well it’s true carbon booms in general are ridiculously expensive. But the brand-new PLATINUM SLS also might very well be the last boom you’ll ever buy.

Light is right but only if it doesn't go to costs of durability. Durability as part of the DUOTONE quality has always been one of the defining characteristics of our products - and it stays that way. Because despite offering the lightest components on the market we hold firmly to the course of our tried and true quality claim. This is ensured by sophisticted engineering, highest quality and more effectively used raw materials combined with the latest processing technologies. The legendary DUOTONE longevity is therefore retained completely, which we guarantee for your with an industry-leading 2 YEAR UNCONDITIONAL WARRANTY!

iFRONT 2.0

THE LIGHTEST FRONT-END ON EARTH! COMBINES THE ADVANTAGES OF PREVIOUS 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. PERFECT FIT GUARANTEED FOR BOTH SDM AND RDM MASTS 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.

OVAL TAIL SECTION

The tail section has similar influence on the overall boom stiffness as the front section, although the influence increases the further you extend the boom length. Unlike the front section where the forces act in multiple directions, 90% of the forces on the tail section occur laterally as the main force comes from the sail pulling sideways. With the forces only occuring in one direction, the most effective geometry here is an asymmetrical oval cross section that is horizontally orientated. This makes the entire boom approx. 30% stiffer!

VTS TAIL

Since 1992 all our sails feature VTS dots clearly showing the right downhaul tension. With the introduction of the VTS TAIL we have finally made the correct outhaul tension visible as well. Due to the integrated visual indicator and rope markings now you have the perfect outhaul trim every session.
