Davis Instruments

<h3>Davis Instruments: Precision Tools for Sailors and Boaters Since 1963</h3><p>Founded in 1963 and headquartered in Hayward, California, Davis Instruments has spent over six decades earning the trust of sailors, power boaters, and weather enthusiasts around the world. What began as a focused engineering effort to bring precision instrumentation to the marine market has grown into one of the most recognized names on the water — a brand whose products can be spotted on racing dinghies, offshore cruisers, and commercial vessels alike.</p><p>Davis Instruments occupies a unique space in the marine world: the brand bridges the gap between serious weather science and practical seamanship. Their legendary Vantage Pro2 weather station has become an industry benchmark for accurate, real-time environmental monitoring, trusted by everyone from backyard hobbyists to professional meteorologists. That same commitment to reliable data collection carries over to every product in their marine lineup.</p><p>On deck and at the helm, Davis products are equally at home. Their <a href="/200714-navigation-parts-accessories-davis-instruments-7311">navigation parts and accessories</a> — including precision hand bearing compasses, sextants, and an extensive library of quick-reference piloting guides — give mariners the confidence to navigate safely whether electronics are available or not. A Davis sextant is widely regarded as an excellent backup for any vessel, blending traditional celestial navigation with modern build quality.</p><p>Few brands have had as much influence on sail trim as Davis. The iconic Windex wind direction indicator has become a fixture at mastheads around the world, while the WindTrak series of wind vanes — featuring sapphire jewel suspension bearings and wind-tunnel-tested durability to 80 knots — represents the gold standard in <a href="/7311-davis-instruments-tell-tales-wind-direction-indicators-accessories-201057">tell-tales, wind direction indicators, and accessories</a>. Whether you sail a 15-foot dinghy or a 100-foot offshore passage maker, there is a Davis wind indicator designed for your rig.</p><p>Keeping a boat securely and safely moored is another Davis strength. Their <a href="/7311-davis-instruments-mooring-snubbers-200696">mooring snubbers</a> — including the innovative LineSnubber with its progressive tension design and the versatile Shockle — protect dock lines, cleats, and hull fittings from the relentless stress of wave action and tidal surge. These solutions are engineered to outlast traditional rubber snubbers and are simple to reposition as conditions change.</p><p>Boat maintenance is never overlooked in the Davis catalog. Their <a href="/7311-davis-instruments-fiberglass-general-purpose-cleaners-200398">fiberglass and general purpose cleaners</a>, led by the fan-favorite FSR (Fiberglass Stain Remover), offer a non-abrasive gel formula that lifts oil, rust, exhaust, and waterline stains from gel-coat and painted surfaces without sanding or compounding. It is one of the most straightforward, effective hull-care products available to recreational boaters.</p><p>For power boaters, Davis also offers practical solutions for the engine transom area, including <a href="/200751-outboard-motor-transom-padssupport-plates-davis-instruments-7311">outboard motor transom pads and support plates</a> and the original Doel-Fin hydrofoil — a product developed by an aeronautical engineer to reduce bow rise and improve planing performance on outboard- and outdrive-powered boats.</p><p>Across all of these categories, Davis Instruments delivers what their customers have come to expect: thoughtfully engineered, field-proven products that make life on the water safer, more efficient, and more enjoyable.</p>

Product Details

The Davis Instruments 352 Rocker Stopper is a hydrodynamic stabilization device engineered to reduce boat roll and rocking motion while moored, anchored, or drifting. This scientifically designed stabilizer effectively dampens the uncomfortable effects of waves, wakes, and swells, creating a more stable and comfortable onboard experience.

Key Features:

  • Hydrodynamic design uses water resistance to counteract rolling motion
  • Effective for boats at anchor, moored to a dock, or drifting
  • Significantly reduces the rocking and rolling caused by waves and boat wakes
  • Deploys underwater to work below the surface
  • Durable marine-grade construction for saltwater and freshwater use
  • Individual unit can be used alone or paired for enhanced stabilization

The Rocker Stopper works by creating drag and resistance underwater, opposing the boat's rolling motion and absorbing wave energy before it can rock your vessel. Ideal for overnight anchorages, fishing trips, or any situation where a stable platform is desired. This is a single unit; multiple units can be deployed for larger vessels or enhanced stability.

Went well. Had to re enter everything because I am having it shipped to where I am working instead of my home. But, for security, I understand that. So, good experience.
