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.

140 to 200 Platinum boom

I first got the platinum boom around year 2000 and I must say I absolutely love it for it's incredibly light weight, small diameter 24mm. So yeah these aspects and the looks were really the selling points for me. Thus I bought a second one. However the only down side that I found is the rubber insert that runs along the tail of the boom(where all the holes are) comes off/gets ripped really easily(this was on my second newer boom). Anyway I'm going to see if I can get a length of electrical heat shrink to fix it, as a replacement tail end is incredibly expensive. Would I buy a third Platinum boom in the future? Yes, of course. Because 90% of the overall design and construction meets my needs. You'll never get 100%, there's always room for improvements. Keep up the good work gang!

Online Store is the best

Love I can get all duotone products directly from the store, the products are well designed, love the design, durability and overall the quality of the products compare to other brands. I do feel super secure incthe water and that makes my sessions more consistent. Keep up the great work and innovating forward!

This boom is an absolute standout

This boom is an absolute standout. It’s incredibly light, which makes handling the rig feel effortless, but it’s also super stiff — so every bit of power from the sail transfers directly into speed and control. I love the precise feel it gives me, especially when I’m fully powered up and carving hard. The build quality is premium, and the grip feels great even with wet hands. It’s one of those upgrades that instantly makes your whole setup feel sharper and more responsive.

140-200

The new shape of the Platinum SLS is right where I want it, super stiff and slim which make sailing whit gloves as easy as possible. With this boom and the platinum mast in my Idol, it’s just works perfect and makes the rig super light feeling. The slim grip gives me a feeling of control when doing moves. Big recommendation from my side.

Best booms in existence (seriously)

I got my first platinum boom last year and have since been hungry to get a second. The mega slim SLS is an addictingly lightweight and slender boom. If you frequently sail anything 5.7 and smaller, this boom will spoil you forever. While with masts I would say gold/platinum could be interchangeable for a moderate sailor, the platinum boom is the thing to splurge on. My second platinum boom was the 160-220 for 6.6/7.3 days. As light as you can imagine for a boom of this size, it gives a feeling of durability and when you are pumping a big sail aggressively to get moving, this boom conveys your energy directly to the sail. 10/10
