Control Single Stand Up Block

Controlled, Accessible Line Handling

The Lewmar Control Single Stand-Up Block is designed to improve the efficiency and usability of control lines by keeping them correctly presented and easy to engage. Purpose-engineered for modern deck layouts, it ensures lines remain accessible and aligned, even when unloaded, supporting confident sail handling in dynamic sailing conditions.

Stand-Up Functionality

Featuring an integrated spring-loaded stand-up mechanism, the block automatically supports the sheave in an upright position when the line is slack. This intelligent design improves line pickup and reduces the risk of lines dropping flat on deck, enhancing speed and accuracy during trimming, manoeuvres, or quick adjustments.

Durable Marine-Grade Construction

Manufactured from robust, marine-grade materials, the Control Single Stand-Up Block is built to withstand the rigours of the onboard environment. The reinforced side plates and precision-engineered sheave deliver strength, wear resistance, and long-term reliability under repeated used and exposure to saltwater and UV.

Smooth, Dependable Performance

Designed to minimise friction and promote efficient rope flow, the block delivers predictable, low-effort operation during both trimming and easing. Its stable configuration supports accurate load transfer and consistent control, helping reduce handling effort and maintain smooth sail adjustment over extended sailing periods.

Installation & Application

Well-suited to control lines, deck organisers, and leads to clutches or winches, the Lewmar Control Single Stand-Up Block integrates easily into both new builds and professional refits. Its compact footprint and practical functionality make it a versatile, professional-grade solution backed by Lewmar’s proven deck-hardware expertise.
