Plunger Stop

Positive Position Control

The Lewmar Plunger Stop is designed to provide secure, repeatable positioning within traveller and track-based sail-handling systems. By offering a positive mechanical stop at defined points along the track, it allows sailors to lock critical sail settings with confidence, ensuring accuracy and consistency under load.

Mechanical Plunger Engagement

At the heart of the design is a spring-loaded plunger mechanism that engages directly into pre-drilled holes or compatible features within the track system. This positive engagement eliminates reliance on friction alone, preventing unwanted movement and maintaining precise trim settings even in strong winds or heavy seas.

Robust Marine-Grade Construction

Manufactured from durable, marine-grade materials, the Lewmar Plunger Stop is built to withstand sustained sailing loads, repeated engagement cycles, and harsh offshore environments. Precision engineering ensures smooth plunger action, reliable engagement, and long-term resistance to wear and corrosion.

Stable, Reliable Performance

By mechanically locking traveller cars on control systems in position, the plunger stop improves trim repeatability and reduces load transfer stress across the rest of the system. This stability enhances sail control, reduces component wear, and increases confidence during high-load manoeuvres and performance sailing.

System Integration & Application

Designed for seamless compatibility with Lewmar track and traveller systems, the Plunger Stop is suitable for both new builds and professional refits. Ideal for mainsheet travellers and other applications where defined, repeatable positions are required, it delivers a clean, system-led solution backed by Lewmar’s long-standing expertise in high-load deck hardware.
