A headboard car including a stanless headboard toggle with a ø14 mm clevis pin and split ring to attach the headboard. Three 80 mm MDS cars in aluminium. 

Dimensioned for a righting moment at 30° heel of maximum 550 kNm on a masthead rigged monohull yacht and 450 kNm on a fractional rig.

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. Since the cars need no external track, there is also less weight aloft.

The MDS cars are easy to keep clean and are easy to install or remove from the luff groove. 

The MDS system is a suitable complement to the Seldén Single Line Reef boom. With such a combination on board, you have a simple and easily manoeuvred system for handling the mainsail in all weathers.

Good looking, quality control needs improvement
Color: Acacia
The shelves are fine but one of the mounting blocks was glued on backwards which meant the holes for countersinking the mounting screwed ended up on the wrong side. It was easy to drill new countersinks so no big deal but a star is docked for quality control. They are cheap and looks good so I can't complain much.

Good looking shelves
Color: Acacia
The shelves look great and are exactly what was needed for the application chosen. It wasn’t an issue for me, but the mounting hardware was missing. I always use my own wall anchors so it didn’t affect me, but it may have others.
