NTR SR Car With Shackle & Plunger Stop

Precise Traveller Control Under Load

The Lewmar NTR SR Car with Shackle & Plunger Stop is engineered to deliver smooth, reliable mainsheet traveller performance with the added security of positive, repeatable positioning. Designed for performance cruising and racing yachts, it offers confident control in high-load scenarios where accuracy strength, and responsiveness are essential.

Self-Riding (SR) Car Design

The Self-Riding (SR) design allows the traveller car to move smoothly along the NTR track under load, reducing friction and eliminating binding during trimming and easing. This controlled, low-resistance movement supports precise sail shape adjustment without the need to fully unload the mainsheet, enabling faster response and improved efficiency in dynamic sailing conditions.

Integrated Shackle Attachment

Fitted with a robust, high-strength shackle, the NTR SR Car provides a secure and versatile attachment point for mainsheet blocks or purchase systems. This direct mechanical connection ensures efficient load transfer while allowing flexibility in rig configuration to suit a wide range of deck layouts and sail-handling arrangements.

Positive Plunger Stop Positioning

The integrated plunger stop enables the car to be mechanically locked at defined positions along compatible drilled NTR tracks. This positive engagement eliminates reliance on friction alone, ensuring that traveller settings remain secure and repeatable under sustained load. The result is consistent trim accuracy, particularly valuable in performance sailing where repeatable traveller positions are critical.

Marine-Grade Construction

Manufactured from durable, marine-grade materials and precision-engineered to Lewmar’s exacting standards, the NTR SR Car with Shackle & Plunger Stop is built to withstand sustained sailing loads, shock forces, and frequent adjustment. Its robust construction offers excellent resistance to corrosion, wear, and fatigue in demanding offshore and performance environments.

Smooth, Confident Operation

Carefully engineered bearing surfaces and internal load paths ensure predictable, low-friction travel across the NTR track. Combined with the secure engagement of the plunger stop, this design delivers a balance of smooth movement and firm positioning, enhancing handling confidence and reducing wear on tracks, cars, and associated deck hardware.

System Integration & Application

Designed for seamless compatibility with Lewmar NTR traveller systems, the NTR SR Car with Shackle & Plunger Stop is suitable for both new installations and professional refits. Commonly specified for mainsheet traveller systems on performance cruisers and race yachts, it offers a refined system-led solution backed by Lewmar’s long-standing expertise in high-load sail-handling hardware.
