Quick functionality points on the base system:

• Double inverted XXL pulleys to save lots of power for pulling downhaul.
• Easy clean free threading through pulley to use gravity to insert the rope.
• Free cleat for no rope friction when down hauling.
• Rigs on both sides as the cleat is on the side of the pulley system.  

The 2XXL pulleys allow you to downhaul the sail with much less power than with a normal wheel size. More space to insert the rope in the pulleys. The cleat has no bridge on top to guide the rope when downhauling. This gives much more freedom to pull, less friction, and when combining the two characteristics, it makes downhauling much lighter and easier. There is no need to have cleats on both sides for rigging on port tack or starboard tack as the cleat is free and easy to lock the rope on both tacks.

The extension tubes are made from strong T8 grade aluminum and are available in lengths of 32 cm/48 cm with adjustment increments of 2 cm. The extensions can be sailed at the full 32 cm or 48 cm extension heights and are supplied with the original Marlow 3.8 mm Formuline rope.
