Upgrade your sailboat's rigging with the Lewmar Control Block, a compact powerhouse designed for seamless handling of lighter loads like control lines, travelers, and outhaul systems. Sailors appreciate its featherlight construction that doesn't compromise on performance, making it a go-to choice for both racing dinghies and cruising keelboats where every ounce counts. Crafted with innovative materials, this single block delivers smooth line flow and effortless resets, even in choppy conditions.
Beyond the basics, these blocks stand out in real-world sailing. The fiber-reinforced cheeks shrug off impacts from accidental knocks against booms or rails, while the stainless steel ball-bearing race minimizes drag for quicker maneuvers during tacks and gybes. Optimized for hand-held operations, it lets you feather the load without fighting friction—perfect for short-handed crews or when trimming on the fly.
Engineered for precision, this block handles up to 440 pounds of working load while accepting 8mm lines over a 30mm sheave—ideal for common control line diameters on modern sailboats.

Integrate this block into your setup for vangs, cunninghams, or reefing lines where frequent adjustments are key. Pair it with low-stretch Dyneema lines for the smoothest operation. During installs, ensure lashings are pre-loaded to prevent slippage under load. For longevity, rinse after every outing and inspect bearings annually—though the self-flushing design makes corrosion a non-issue.
In racing scenarios, its reduced weight shaves grams off your boat's tally, while cruisers love the black finish that blends discreetly with carbon rigs. Unlike heavier metal blocks, it won't fatigue your hands during long passages.
