Original Duotone product information

The following manufacturer specifications describe the product range when new. Your purchase is for the individual used item shown in the photographs.

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

The new DUOTONE-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.

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.
