TB Car With 3 Upstands, 2 Double CL Sheaves

Maximum Control for High-Load Traveller Systems

The Lewmar TB Car with 3 Upstands & 2 Double Control Line Sheaves is engineered to deliver precise, powerful traveller control in demanding sailing environments. Designed for yachts carrying substantial mainsheet loads, this advanced traveller car combines stable track engagement with refined control-Ine management, supporting confident sail trimming in cruising and high-performance applications.

Track-Bearing (TB) Car Design

The Track-Bearing (TB) configuration is purpose-designed to transmit high loads directly into the traveller track, maintaining accurate alignment and predictable movement under tension. This stable load path ensures smooth, controlled travel along the track, reducing binding and improving consistency when trimming or easing under load, particularly valuable on yachts with large mainsails and high-powered applications.

Three Upstands for Optimised Line Management

The integrated three-upstand arrangement elevates the control-line sheaves above the car body, maintaining clean lead angles and keeping lines clear of the deck when unloaded. This configuration improves ergonomics, reduces the risk of line snagging, and supports clean feeds into clutches or cleats, particularly in high-traffic cockpit areas and performance-oriented deck layouts.

Twin Double Control Line Sheaves

Equipped with two double control line sheaves, the car allows control lines to be led cleanly and symmetrically from both sides of the traveller. This balanced, multi-sheave arrangement minimises friction and distributes load evenly, delivering smooth, responsive traveller adjustment with reduced handling effort and significantly lower wear on control lines during repeated high-load trimming.

Smooth, Dependable Performance

Precision-engineered bearing surfaces, sheave geometry, and internal load paths ensure consistent, low-friction operation across the full traveller range. This refined movement supports accurate sail-shape control, improves trimming feel, and contributes to long-term system reliability during extended cruising or intensive race programmes.

Marine-Grade Construction

Manufactured from durable, marine-grade materials and engineered to withstand sustained loads, shock forces, and repetitive adjustment, the Lewmar TB Car with 3 Upstands & 2 Double Control Line Sheaves is built for long service life in harsh marine environments. Its robust construction resists corrosion, deformation, and wear, maintaining dependable performance offshore and in demanding conditions.

System Integration & Application

Designed for compatibility with Lewmar traveller track systems, the TB Car with 3 Upstands & 2 Double Control Line Sheaves is suitable for both new installations and professional refits. Commonly specified for mainsheet traveller systems on performance cruiser and offshore race yachts, it delivers a refined, system-led solution where strength, control line efficiency, and clean deck integration must work seamlessly together, backed by Lewmar’s long-standing expertise in high-load sail-handling hardware.
