TB Mainsheet Car With Shackle, Pair of Double Sheaves & Beckets

High-Load Mainsheet Control with Integrated Functionality

The Lewmar TB Mainsheet Car with Shackle, Pair of Double Sheaves & Beckets is engineered to deliver powerful, precise traveller control in demanding sailing environments. Designed for performance cruising yachts and race-ready systems, it integrates load handling, control-line management, and compact purchase capability into a single, highly efficient component.

Track-Bearing (TB) Performance Design

The Track-Bearing (TB) is optimised to transmit high mainsheet loads directly into the traveller track, maintaining excellent alignment and stability. This efficient load path ensures smooth, predictable movement under tension, allowing accurate traveller adjustment even during heavy trimming and dynamic sailing conditions.

Integrated Shackle Attachment

A high-strength, marine-grade shackle provides a secure and versatile connection point for mainsheet blocks or purchase systems. This direct mechanical link ensures efficient load transfer while allowing flexible rigging configuration to suit a wide range of deck layouts and sail plans.

Smooth, Dependable Performance

Precision-engineered bearing surfaces, sheave geometry, and load paths ensure consistent, low-friction operation across the full traveller range. This smooth movement enhances sail-shape control, reduces crew effort, and extends the service life of both traveller and control systems.

Marine-Grade Construction

Constructed from durable, corrosion-resistant marine-grade materials, the TB Mainsheet Car is built to withstand sustained high loads, shock forces, and harsh offshore environments. Its rugged design ensures long-term reliability and dependable performance across intensive cruising and racing use.

System Integration & Application

Designed for seamless compatibility with Lewmar traveller track systems, the TB Mainsheet Car with Shackle, Double Sheaves Beckets is ideal for new installations and professional refits. Commonly specified for high-load mainsheet traveller systems, it provides a refined, system-led solution where strength, efficiency, and control must work together, backed by Lewmar’s long-standing expertise in sail-handling hardware.
