Pros & Cons

  • C40 is the strongest RDM mast in the range
  • Durability
  • Integrated ferrule allows the mast the bend cleanly at the joint
  • Less reponsive than RDM C60, C80 and C100 spec masts
  • Mastbag is not included - but is available as a separate option

FAQ

Which masts do you measure for the data of the Mast selector Matrix Tool?
Mostly we take multiple C100 masts as the reference of various brands, in general those represent the most accurate bend curve of the sails. This is because sail brands design the sails to perform best on those C100 masts. We also found quite big differences in tolerances regarding production with all brands. Fluctuations of bend curves and stiffness from +/- 1-2 points (bend curve) which proves that none of the brands are 100% consistent. So we measure several masts per brand and take the average of those measurements into account when constructing the Mast Selector Matrix Tool.
Can I interchange top and bottom mast pieces of Unifiber masts - for example a 430 bottom with a 400 top?
Because of the integrated ferrule system we use, each top and base match a pre-defined conical shape determined by the optimum load distribution for that model. In production the top is made to fit precisely on the base of the relevant model. Different bend curves alos have different wall thickness as well as varying geometric shapes, so it's technically not possible or advisable to exchange base and top parts.
What is the internal diameter of Unifiber's RDM masts?
Unifiber RDM masts have a 33-mm. internal diameter up to 600 mm. from the base, tapering to 32mm above 600mm.
What's the minimum overlap required for a mast extension inside a Unifiber mast?
Unifiber recommends a minimum of 100 mm. of mast extension to overlap the inside of the mast to prevent stress load damaging the base of the mast.
What levels of breaking strain can a Unifiber mast take?
In testing Unifiber masts can endure stress of up to 180 kg.
How far into a Unifiber RDM mast doest the internal diameter stay the same width?
Unifiber RDM masts stay at a constant 33 mm. internal width up to 600 mm. into the base section. Beyond 600 mm. the internal width tapers to 32 mm.
Why do Unifiber SDM 100% masts cost more proportionally than the 40/60/80% models?
Unifiber's SDM C100 masts have an additional (radial) compression layer for durability reasons, since many brands' C100 masts were breaking due to an increase in luff curve, on race sails especially. As SDM C100s need to be light and durable there are more costly materials used to reach this objective. Without the additional compression layer the durability aspect would be not as good. We are confident you will find our masts perform well in all 3 bend curves. Reviews - Help us by reviewing our products:
What does 1 Year Unconditional + 1 Year Conditional warranty cover?
Warranty is valid 2 years after date of purchase. When making a warranty claim in the first year the product is unconditionally warranted. When making a warranty claim in the 2nd year the product must have clearly suffered from a manufacturer error.
Why are high specification masts not standard supplied with a mastbag?
According to industry standards at least C80 and C100 masts are supplied including a mastbag. At Unifiber we choose not to for 2 reasons. The 1st reason is that we aim to offer our product for the best price to quality ratio and for example if you have for instance an existing mastbag or equipment bag a mastbag is not neccessary. The 2nd reason is that we have rental centers as customers who are not in the need of mastbags.
