Selden System 30 Performance Mainsheet Car Double Fixed Block – Ball Bearing

The Selden System 30 Performance Mainsheet Car with Double Fixed Blocks (Art. 443-351-05) is designed for advanced mainsheet systems where efficient load distribution and smooth trimming are essential.

This traveller car features a double fixed sheave configuration, making it ideal for German sheeting systems where the mainsheet is led to both sides of the cockpit. This setup improves trimming ergonomics and allows better sail control from either side.

The system provides a 6:1 purchase ratio, reducing trimming loads while maintaining precise control over the mainsail. The sheaves are precision-machined aluminium wheels running on Torlon® ball bearings, ensuring extremely low friction and smooth operation even under load.

The articulating sheave housing aligns automatically with the load direction, improving efficiency and reducing wear. This ensures consistent performance in dynamic sailing conditions.

Constructed from black anodised aluminium with stainless steel components, the car combines high strength, low weight and excellent corrosion resistance. Designed for Selden System 30 Performance tracks (30 mm), it is suitable for yachts up to approximately 45 ft.
