Description

Efficient Control for Performance Systems

The Lewmar HTX Single Block with Swivel Head is engineered to deliver smooth, reliable handling of high-load running rigging in modern sailing applications. Designed for performance cruising and racing yachts, it provides precise control, efficient load management, and durable operation where consistency and responsiveness are essential.

Single-Sheave Performance Design

The single-sheave configuration offers a clean, direct lead for control lines, making it an ideal for deflection points, fine-tune systems, and lightly to moderately loaded trimming applications. Its compact form supports space-efficient deck layouts while maintaining predictable, low-loss load transfer under sail.

Self-Aligning Swivel Head

Fitted with a freely rotating swivel head, the block automatically aligns with changing lead angles as loads move through the system. This self-orienting action reduces sideloading and friction, promoting smooth rope flow and extending the service life of both rope and hardware in dynamic sailing conditions.

HTX High-Strength Construction

Manufactured using Lewmar’s advanced HTX composite technology, the block delivers exceptional strength-to-weight performance. Reinforced composite cheeks and a precision-engineered sheave are designed to withstand demanding working loads while minimising flex, friction, and long-term wear, ensuring dependable performance in challenging deck environments.

Smooth, Low-Friction Operation

Optimised sheave geometry ensures efficient rope movement during trimming and easing, delivering predictable handling and reduced effort at the control line. The stable, well-balanced design supports accurate sail adjustment and consistent feedback, even during prolonged or high-workload sailing.

Installation & Application

Well-suited to control lines, deflectors and performance-oriented deck systems, the Lewmar HTX Single Block with Swivel Head integrates seamlessly into modern cruising and racing yacht layouts. Its combination of strength, adaptability, and compact efficiency makes it a professional-grade solution backed by Lewmar’s proven deck-hardware expertise.
