Seldén’s collaboration with sailmakers all over the world goes way back and the synergy provides well functional sail handling in all respects. Our Sailmaker Hardware is the connection between the rig and the sails and a real game changer for your sailing experience.

IWS – INNER WHEEL SLIDER (C137 C153 C180 C192 C208 C225 C242 C261 C280)
The four wheel IWS car simplifies hoisting, reefing and dousing and is used for Seldén’s newest C-sections. The side load created by the full-batten is taken up by the wheels as the slider tilts to the side and a buffer bearing centers the slider in the groove. The mast groove and the car makes for a perfect match handling loads from all direction without any extra hardware fitted to the mast. The full-batten cars come with a M10 stud and the intermediate cars with a bushing for webbing.
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 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.
OWS is an excellent upgrade from traditional sail slides to reduce friction when hoisting and dousing the main sail.
It fits earlier models of Seldén sections (E-sections and D-sections) and most other mast makes. The four wheels roll on the aft side of the mast section while the slug slides inside the luff groove. The depth and the shape of the slug is designed for dedicated mast sections and there are five different designs to chose between. Our guidelines show you which to select.

Round Circulating Ball Bearings
The RCB system offers a radical solution to the problems with jamming sliders in an old mast. Basically, you fit a track on your mast and cars with Torlon ball bearings eliminate all that unnecessary friction you are so fed up with. The RCB track, which comes complete with screws and special nuts, is easy to fit on a Seldén E- or D-section. Just push the track into the original mast groove and tighten up. The attachment system is tailored to Seldén masts, but it will also fit those with a similar luff gap (approx. 6 mm or 1/4″). Other masts can be fitted with the track by screwing it directly in place.
Seldén’s composite receptacles are available for boats up to approximately 45’ and allow for round and flat battens. They all connect to cars with M10 studs such as MDS, OWS, IWS and RCB.
To open the cover, just unscrew the locking screw a few turns and push the cover back. If you would drop it – it is secured to the body with a safety cord. Through the slot in the cover you will see the tensioning device and indicators on the cover will enable you to record the perfect batten tension. A unique feature of the A17, FA-22 and FA-30 is that the tension of the batten can be adjusted both from the front end of the fitting as well as from the rear.
