DESCRIPTION

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.
