ALL OUR RDM MASTS WILL FIT CONSTANT CURVE SAILS FROM OTHER BRANDS. 

OVERVIEW

RDM-INVERTED REFLEX

OUR SUPPLIER IS BASED IN ITALY AND PRODUCES IN ITALY. THIS IS TO ASSURE NOT ONLY PERFORMANCE BUT ALSO SAFETY IN THE HARDEST CONDITIONS.

Thanks to update of new machineries, we were able to work out a new finish from our masts and introduce new technology in the constructions. 2 versions only, to simplify and offer only the best. 

Most of the masts might look the same, but often produced by different manufactures with different machinery, materials, climates, and technology, Even if the curve or Imcs numbers might be the same, the performance outcome once down hauled in a sail, will be different. Being the backbone of your windsurfing sail, it makes a very important accessory for the rig. The same as having a suit tailor made. The masts have been re-worked as they need to offer in the different sizes, different performance. A 400rdm needs to power up a light wind 5.6 wave sail or high winds catapults on a small slalom sail, while a 340 needs to hold huge landings in extreme conditions on a 3.3 wave sail. The curve and stiffness of the mast needs to be developed accordingly.  Most of the masts on the market are constant curve, but this is only a general term to explain the characteristics. What is important is the curve percentages values of the bottom and top sections of the mast, including materials, shapes, and reflex. These are values which are very different in each sail brand, and often kept secret. Therefore, the best efficiency is reached by having an integrated rig.

THE NEW K’S GENERATION

RDM-I: REDUCE DIAMETER-INVERTED

Once you take out the mast from its mast bag, do not be thinking that something is wrong. The ferrule is part of the top, and not part of the bottom anymore. Therefore, the rdm is now being called RDM-I. After testing with our wave team, the masts, we have discovered that landing hard flat or nosedive jumps, was creating extra stress to the top, where the ferrule would enter it. By having the ferrule being part of the top, the stress is taken out and the tops do not suffer the extra stress that could bring in the worst case to breakages. We have decided to clean up our RDM-I range by offering 2 very distinctive models. The K87 and the K97. 87% carbon mast to bring a durable mast with the highest carbon % possible. A 100% carbon mast is the K97, but with extra reinforcements to give the extra durability to the normal 100%, making itself a 97% carbon mast. A new rubber cap at the joints, to clean up the inside part of the mast from dirt, while uniting the top to the base.

K97 CARBON MAST

K97 CARBON MAST: The best possible performance for your sail for tough riders and conditions. Great pumping response, acceleration, light feel and absorption of the hardest conditions for optimal comfort and control. Extra reinforcements added to increase strength for toughest conditions. Inverted ferrule for higher balance and structural strength. Knowing the mast will used in waves and strong wind slalom, we made sure to add the extra reinforcements to increase strength for toughest conditions. Bringing a 100% mast close to the durability of an 80% carbon mast.

WHY THIS MAST: No compromise in its performance. Best reflex and light weight. If you choose this mast, it’s because you want to have the best possible product on the market. Probably the lightest mast with this percentage.
