NTR TB Car With Upstand & 1 Pair CL Sheaves

CONTROLLED PERFORMANCE FOR HIGH‑LOAD TRAVELLER SYSTEMS

The Lewmar® NTR TB Car with Upstand & 1 Pair Control Line Sheaves is engineered to deliver smooth, precise traveller control in demanding sailing environments. Designed for performance cruising and racing yachts, it combines robust load‑handling capability with refined control‑line management to ensure accurate, dependable sail trim under sustained load.

TRACK‑BEARING (TB) CAR DESIGN

The Track‑Bearing (TB) configuration is optimised to transmit loads directly into the Lewmar® NTR track, maintaining stable alignment and predictable movement during high‑load trimming and easing. This efficient load path reduces friction and binding, ensuring consistent traveller performance—even in aggressive sailing conditions with powerful mainsails.

INTEGRATED UPSTAND FOR OPTIMISED LINE LEADS

The built‑in upstand raises the control‑line sheaves above the car body, improving line lead angles and keeping control lines clear of the deck when unloaded. This enhances accessibility, reduces the risk of snagging, and supports cleaner feeds into clutches or cleats—particularly valuable in high‑traffic cockpit layouts and performance‑oriented installations.

SINGLE PAIR OF CONTROL LINE SHEAVES

The integrated pair of control line sheaves provides smooth, low‑friction routing for traveller lines, enabling efficient trimming from both sides of the track. This balanced configuration ensures consistent load distribution, improved handling feel, and reduced wear on control lines during repeated adjustments under load.

MARINE‑GRADE CONSTRUCTION

Manufactured from durable, corrosion‑resistant marine‑grade materials, the Lewmar® NTR TB Car is built to withstand sustained loads, dynamic forces, and harsh marine environments. Its robust construction ensures long‑term reliability and consistent performance in both offshore and coastal sailing applications.

SMOOTH, RELIABLE OPERATION

Precision‑engineered bearing surfaces and load paths deliver low‑friction, predictable travel across the NTR track. This smooth operation supports accurate sail‑shape control, reduces crew effort, and extends the service life of both the traveller system and associated deck hardware. 

SYSTEM INTEGRATION & APPLICATION

Designed for seamless compatibility with Lewmar® NTR traveller systems, the NTR TB Car with Upstand & 1 Pair Control Line Sheaves is suitable for both new builds and professional refits. Commonly specified for mainsheet traveller systems on performance cruising yachts and race boats, it offers a refined, system‑led solution backed by Lewmar’s long‑standing expertise in high‑load sail‑handling hardware.
