Comment from the Wind Lounge team:

The aluminum windsurf mast extension is a classic from Point-7 . It has been known for years as an extremely solid and practical addition to every conceivable rig. The special feature is the double clamp. This allows a sail to be set up from both sides. This may sound trivial, but it is very useful in many situations. In addition, some sail brands use a reverse furling system - here too, the extension clearly scores points. The workmanship is high quality and the pulley system runs smoothly.

The 3.8mm Formuline rope is recommended. This is supplied, but should be replaced at regular intervals. You will of course find this in our store in the future. 

Detailed technical data can be found in the table below. 

Product description from Point-7:

Having the right tools, is half the work done. The Point-7 extensions are based on a very simple indestructible system that is quick and simple to use and allows for effortless downhaul, even on very big sails.
The pulley and cleat system is attached directly onto the aluminum tubing, with no crossing lines. With the brass rollers, downhaul efforts are reduced to the absolute minimum.

Quick functionality points on the base system:

• Double Cleat for rigging on both Starboard and Portack side.
• Guided Cleat for easy rope blocking
• 3 rolls for use with 4 pulley systems on the sail.
  
  
  The extension tubes are made from strong T8 grade aluminum and are available in lengths of 32 cm/48 cm with adjustment increments of 2cm. The extensions can be sailed at the full 32cm or 48cm extension heights and are supplied with the original Marlow 3.8mm Formuline rope.
