FEATURES
FEATURES
- The MDS full-batten concept - Full support in all directions.
- As the name implies, Seldén’s MDS (Multi-Directional Support) cars are supported in all directions, making sail handling simpler.
- A full batten always creates a side load on the cars, particularly when you release the halyard for taking a reef.
- Each MDS car has side-load absorbing wheels that run against the guiding flanges in the luff groove.
- The interaction between the mast section and the MDS car deals with longitudinal loads, as well as side loads.
- This is the essence of the MDS concept.
