Ritchie Navigation

<h3>Over 170 Years of Navigational Precision</h3><p><strong>Ritchie Navigation</strong> has been shaping the course of marine navigation since 1850, when physicist and inventor Edward S. Ritchie set out to build the first American-manufactured magnetic marine compass. That pioneering spirit — rooted in engineering rigor and hands-on craftsmanship — has carried the company through more than 17 decades of continuous innovation. Today, Ritchie remains a privately held, family-run operation based in Pembroke, Massachusetts, and is still recognized as the marine industry leader in the manufacture of recreational and commercial magnetic compasses.</p><h3>A Legacy Built on Innovation</h3><p>Ritchie's history reads like a timeline of compass technology itself. In 1861, the company delivered the first-ever liquid-filled compass to the U.S. Naval Observatory — a design so groundbreaking that a model of it is still on display at the Museum of Science in London, the only foreign product to receive that honor. Post-World War II, Ritchie capitalized on newly developed materials science, introducing spherical bowls, internal gimbals, jeweled pivot systems, and lightweight aluminum dials to improve stability and accuracy. Later, acrylic domes replaced glass and high-strength plastics replaced metal castings, making compasses more durable and easier to maintain.</p><p>Today, every Ritchie compass features a hardened steel pivot and triple cup sapphire jewel movement, microscopically matched to deliver smooth dial operation and fast heading lock-on — even in the most demanding sea conditions. There are no plastic pivots or jewels in any Ritchie compass, a testament to the brand's commitment to uncompromising quality.</p><h3>Compasses for Every Boater and Every Boat</h3><p>One of Ritchie's greatest strengths is the sheer breadth of its lineup. Whether you're a weekend recreational boater, a competitive sailor, a kayak explorer, or a professional boat builder specifying instruments for production vessels, there's a Ritchie compass built for your application. Popular series include the Voyager, Globemaster, Navigator, Helmsman, Explorer, SuperSport, and Angler — each engineered for specific mounting styles, vessel types, and dial preferences. The brand also produces the RitchieSport® series for on- and off-road vehicles, the Kayaker series for sea kayaks, and the Trek&trade; series with Mossy Oak&reg; camouflage coloration for outdoor enthusiasts.</p><p>Browse the full selection of <a href="/7528-ritchie-navigation-compasses-200280">Ritchie Navigation Compasses</a> to find the right model for your vessel, whether you prefer flush mount, surface mount, binnacle mount, bracket mount, or bulkhead mount configurations.</p><h3>Why a Magnetic Compass Still Matters</h3><p>GPS devices are powerful tools, but magnetic compasses offer something no satellite system can: real-time heading data that requires no power, no signal, and no electronics. A magnetic compass functions independently of any external infrastructure, making it an essential backup — and often a primary reference — for any serious mariner. The ideal setup for most boaters combines a quality GPS system with a reliable magnetic compass, and Ritchie has been the trusted choice for that magnetic compass for generations.</p><h3>Parts & Accessories to Keep You Calibrated</h3><p>Ritchie Navigation doesn't stop at the compass itself.
