     DETAILS

Uni.XT Series

UNI.XT – the most technically advanced and yet the most lightweight standard aluminium extension we have ever built. Now also built using SLS carbon technology to create the most lightweight extension in the world.

When it comes to standard extensions, everyone has probably experienced some nasty surprises at some point. They rarely fit with the rope alignment on the sail, most of them need high downhaul forces, and more often than not the mechanism for adjusting the height is extremely fiddly. Before designing the UNI.XT we analysed all of these issues in detail and came up with workable solutions. The strong and super-solid UNI.XT extension may look like numerous other standard extensions at first glance, yet it is replete with innovations which make it a far superior product. The latest version comes with a completely new adjustment ring, which offers a unique feature: based on the tried-and-tested SDM adjustment ring, the RDM version now for the first time ensures that the aluminum tube does not come into contact with the mast anymore, which avoids any contact corrosion. No other RDM extension can offer that! In order to guarantee the same durability despite the reduced diameter, a double-walled construction of 7075 aluminum outer tube and ovalized T8 inner tube is used (patent pending).   

   

     Tips & Tricks

Using all 3 rollers of your sails tack roller vs. quick loop using only the 2 outside rollers â–ºvideo

The UNI.XT allows the most universal usage of any extension out there. With its different thread options it fits to any sail brand and -model without the rope ever getting crossed or tangled.

In addition you can either use all 3 rollers at the sail plus the 2 rollers at the base (THREAD THROUGH OPTION = 6:1 power-ratio).
Or you just loop the rope through the 2 outside rollers at the sail and over 1 of the rollers at the base (LOOP LOOP GO OPTION = 4:1 power-ratio).

When designing the UNI.XT we measured the downhaul forces of both options on all kind of sails.
We've found out these interesting facts:

  1. Threading the rope through all rollers (without the rope getting crossed) takes at least 4 times as long as just looping the rope.
     
  2. When downhauling a cambered slalom sail the forces necessary are nearly 3 times as high as when downhauling a no-cam wave sail (160 kg vs. 60kg).
     
  3. With a 6:1 power-ratio you need to pull twice as much rope-length as with a 4:1 ratio. Therefore with a 4:1 ratio you can downhaul the sail in one go whereas with a 6:1 ratio you need to retighten the rope.
     
  4. In theory with a 6:1 power-ratio the downhaul forces should only be half as high compared to a 4:1 ratio. Though in real life the friction loss at all rollers reduces the downhaul tension by only 15% at most (wave sail: 57 kg vs. 60 kg / slalom camber sail: 135 kg vs. 160 kg).
     

HERE ARE OUR RECOMMENDATIONS:

  • For no-cam sails the massive comfort- and speed advantages of the 4:1 ratio (LOOP LOOP GO OPTION) outweigh the very slightly reduced downhaul forces of the 6:1 ratio
     
  • On cambered sails the downhaul forces are so massive that even a small reduction helps. Here you should use the 6:1 ratio (THREAD THROUGH OPTION)

Pull vs. push
  • Downhauling is a combination between pulling with your arms and lower back and pushing with your feet.
     
  • To avoid back strains you should try to push more with your feet (min. 60%) versus pulling with your arms/back.
     
  • With all current standard extensions so far you could just prop with one foot against the cup.
     
  • With the UNI.XT you now can prop with both feet against the base cup.
     
  • This results in 30% more efficient trimming and reduced back strain.

UNI.XT maintenance
  1. Over time even stainless steel and aluminium parts get affected by salt water. Therefore after holidays in salt water please put the UNI.XT in a bucket full of sweet water. 
  2.  

  1. Once or twice a year spraying some WD40 or Caramba onto both axles helps to reduce the friction and thus reduces the downhaul forces. When done wipe the UNI.XT clean with a cloth to remove all excess oil. Especially the teeth of the cleat must be free of oil.
Can I really use the full adjustment range of the mast extension

With alloy booms we don't recommend to use the whole extension range - at least if you're a heavy guy and/or are sailing in heavy conditions.
However with mast extensions you can use the entire range. At least our tests and experience have shown no difference in durability by doing so.
