Reptile Reverse



The industry standard terms describing windsurfing mast bend curves are:

  • 0-8 = Hard top
  • 9-13 = Constant Curve
  • 14-20 = Flex Top

We not only measured all the mast of the market on our machine, but we constantly speak with many sail makers analyzing all the windsurfing sails geometries of the market. There are countless bend curves for the masts and many sail brands stay in between of the three popular terms above mentioned. They call them in many ways, hard, flex, progressive-flex, mid-flex, diagonal, and more and more.
In the bare reality, most of the windsurfing sails in the market can be rigged with many different masts. For example, a stiff bottom section can be fitted with a constant one, a constant top section with a flex one, a hard-top section with a constant one. It’s not the best option, but it could be done.
During the sail development and many hours spent on the water, riders and designers find a “compromise” (read the “perfect tuning”) between the sail shape and the mast curve. As it’s easily understood, this perfect tuning is affected by the weight and skills of the riders, by the wind and water conditions, by the boards and boom shape used. All variables that can be good for the most, but not for all!
Our gear is affected by the tolerances; if the sails cutting and sewing process are really fast, cut panels and stitches could have tolerances of some millimeters; and millimeters make the difference changing from bend curve to a different one. Pre-preg carbon materials have tolerances, epoxy resins have tolerances, every manufacture process has tolerances that can modify the results of the “perfect tuning” found by the developers.
With our digital bend curve machine, we measured hundreds of masts; each mast has been measured detecting 7 points. At the end of the story we found an average of plus/minus 2,5 % of tolerance on the bend curve results. It means a difference from 2 to 5 mm from mast to mast, it means a mast completely different than the one for example, used by the sail maker and pro riders to developed the sail.
Considering this huge tolerance, we can say that with the Reverse you have a real option to properly rig all the sails of the market. Reptile Reverse covers the range from 61% to 64% on the bottom section and from 74% to 77% on the top sections. The different bend curve of the bottom section will define a different curve of the top section as well.
With one mast you can choose the best tuning for your self’s, switching from CONSTANT/FLEX to HARD TOP depending on your weight, your style. the sails size and the conditions.
Try to explore the different feelings of your sails with our new REPTILE REVERSE RDM.


ONE mast to fit ALL the sails of the market. The exclusive Reptile Reverse is the only mast in the World having TWO different bend curves.
Its cylindrical bottom section is made with a complex carbon plies layup and can be connected to the top section from both side ends, called
“CONSTANT/FLEX ” and ” CONSTANT/HARD”. Depending on the side end used, you obtain the desired bend curve


If you have a sail with a constant/ flex top bend curve (duotone,naish, neil pryde…) the side end CONSTANT/FLEX is your first option. Connect
the bottom section to the top section keeping the CONSTANT/FLEX sticker on the bottom (where you connect the extension), and enjoy your sailing.

Moreover, with Reptile Reverse you can customize the power of your rig depending of your weight, style, sail, wind. What the pro riders make
with many masts and hours spent in the water, with the Reptile Reverse it can be done with one mast in a few minutes. Turn your bottom section
upside down and find new sensations!


Per I possessori di vele tendenti all’Hard top ( come ad esempio Severne) noi suggeriamo di utilizzare l’estremità CONSTANT/HARD( come chiaramente indicato sull’albero). È sufficiente comporre l’albero mantenendo la scritta CONSTANT/HARD dal lato della prolunga, ed il gioco è fatto.

Inoltre, con il Reptile Reverse è possibile modificare le caratteristiche della propria vela semplicemente invertendo la base! Prova entrambe le soluzioni, e scegli quella più adatta al tuo peso e al tuo stile!
