R2 + UNCOMPROMISING FUNCTIONALITY and VALUE!
R2 PLUS is the new 2025 version of our Boom in 100% carbon. The main difference in this new version is the width of the terminal, now increased to 14.5 cm, almost 1 cm more than the previous version. Thanks to this modification, we have further expanded the angle that creates a new geometry between the front and rear part. This ensures more uniform sail traction and a better profile (without the sail resting on the opposite arm of the Boom), making the equipment more manageable and less tiring whether it is wave, freestyle, or freewave.
In this new version, the solid rubber anti-abrasion strips have been extended on the shoulders of the Boom, to resist wear and prevent damage to the grip caused when rigged on rough surfaces and asphalt.
For the 140-190 as a degree of stiffness, we have chosen the Standard (FL) (the Boom Hatropina can have different degrees of stiffness), while for the 145-195 we have chosen the degree High Stiffness (HS) which can be used by heavy riders and with larger sail ranges.

BENEFITS:
Customization:
The Boom Hatropina can be available on request in two different stiffness levels, Standard (FL) and High Stiffness (HS), the choice depends on the rider's weight, sail range, and rider's needs.
Materials:
Strictly UD (unidirectional) prepreg Carbon is used, and exclusively PAN High Strength (HS) with a modulus value that resides in the threshold between normal modulus and intermediate modulus (IM).
UD instead of carbon fabric, for the undeniable superiority of its final properties (stiffness, strength, weight, reactivity, less fatigue from cyclic loading). What is the challenge of UD carbon? It is the delicate nature, difficulty in handling it, and the meticulousness required to apply it correctly, (thus requiring very high know-how and higher costs) which is why practically no Boom manufacturer uses it.
On our Boom, you will never see the distinct carbon weave with the super shiny appearance seen on windsurfing Boom, nor interruptions in the fiber alignment within the fabric.
Curve:
The super ergonomic curve is oriented towards maximum driving comfort with a natural grip and wrist curve in all conditions.
Handle:
We use the Chinook Pro1 Head handle, one of the best and safest on the market, with integrated adapter, it fits both SDM and RDM masts.
Clips:
Double pin clips with positive lock. We mount longer pins with molded pin wells, reinforced and thicker tubes around the pin holes. This ensures that the pins are laterally anchored in their seat and cannot sway and transfer breaking loads to its root or the clip carrying it. The arms boast lower pin-to-hole tolerances than other Boom and are much more durable.,
Clamp area molded with silicon carbide (SiC) coating to combat abrasion from sand ingress. The PA sealing bushing keeps sand and water out of the Boom and protects the terminal from wear from torsional and axial loads
Grip:
The material we use is Aortha EVA, produced in the UK and bought exclusively from the UK. It is a unique material for its mechanical and aging properties, and it is also suitable for skin contact, making it the most used material for podiatry applications worldwide. The Boom features two grades of this precious EVA, in a dual-density execution: high density along the entire outer perimeter of the Boom and the trapeze line area and medium density for the remaining inner part. All sections are beveled and glued with an orientation such that the seams are not stressed by manual traction
Protections:
Wear-resistant strips on the underside of the trapeze line area
Rubber bumpers on the terminal
Full rubber wear-resistant strips on the shoulders of the Boom to rig without damage on rough surfaces and asphalt
Like all HATROPINA products, even this Boom has quality and performance standards that are significantly above the market average. Creating the lightest, stiffest, most durable, and high-performing Boom on the market was our goal (achieved). Even in this case, we extensively and carefully tested various prototypes before going into production with the final version.
The HATROPINA products break away from the mass product logic of "everything the same" of the big majors, and in this case too, we turned to extremely capable manufacturers with very high construction standards, using the best materials and having meticulous, artisanal, and customized care for the final product
Our manufacturer creates its own Carbon Prepreg, the cornerstone of the entire process, creating a personalized and customized carbon production for the Boom Hatropina, with the main objective of producing the best stiffness/weight ratio. Each Boom is built individually with unique methods and a technologically advanced process, resulting in lightness, stiffness, ergonomics, and geometry. Boom diameter 24.5mm incredibly light, at the same time super stiff and surprises with incredible reflex and drive. Assembled with wide preload for zero play. Safe, stiff, and stable even at full extension
Both the main body and the terminal are custom-built to achieve the correct distribution for a perfect balance between the front and rear hand. Additionally, each single arm is subjected to a final tensile test to ensure that the actual stiffness is true to the specifications. Note that the weight distribution is towards the front; where there is the connection and distribution of energy/power that is transmitted from the Board through the Mast. The light rear section allows the rig to move freely without effort during maneuvers. This is in direct opposition to the usual constructions of other brands that, to give "added stiffness," make larger and heavier rear sections
