Lewmar 29901341BK Sailboat Block — Product description
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.
Why Sailors Trust Lewmar Control Blocks
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.
- Exceptional Durability: Long Fiber Technology weaves strength into every component, outlasting traditional plastic blocks in UV-heavy environments.
- Low Maintenance Design: The flush-through architecture rinses away grit and salt with a simple freshwater hose, keeping it spinning like new after every sail.
- Versatile Mounting: Fixed lashing eye simplifies installation on pad eyes, toe rails, or custom brackets without needing extra hardware.
- Backed by Reliability: Comes with a limited three-year warranty, reflecting Lewmar's confidence in marine-grade toughness.

Pro Tips for Maximizing Your Block's Potential
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.
Simple Care for Lasting Performance
Keep it performing flawlessly with these sailor-tested steps:
- Rinse with fresh water after sailing to expel salt and sand.
- Inspect for wear on the sheave groove and lashing eye.
- Lubricate bearings sparingly with marine grease if resets feel gritty.
- Store in a dry locker to avoid prolonged UV exposure.
This routine ensures it outperforms expectations season after season.
