Founded in the early 1920s by entrepreneur Hans "Action" Broson Sneve, the company began with a unique sales approach—showcasing marine hardware aboard a 55-foot cruiser that sailed from Alaska to Mexico. This hands-on philosophy continues to shape Sea-Dog's commitment to producing hardware that performs reliably in the harshest saltwater environments.</p><h3>Industry-Leading Marine Hardware Manufacturing</h3><p>Based in Everett, Washington, Sea-Dog Corporation operates a 75,000-square-foot warehouse stocking over 8 million parts and runs an injection molding facility with 16 machines producing more than 17 million components annually. The company's extensive product line spans anchoring systems, deck hardware, electrical components, plumbing fittings, and lighting solutions—all engineered with marine-grade materials like stainless steel, brass, and UV-resistant polymers. Sea-Dog's recognition as a multiple-time NMDA Supplier of the Year underscores the brand's excellence in both product quality and customer service, while their on-staff ABYC-certified marine technician provides invaluable installation and technical support.</p><h3>Premium Marine Components for Every Vessel</h3><p>Sea-Dog's <a href="/7549-sea-dog-line-windshield-washers-wipers-replacement-motors-201195">windshield washers, wipers, and replacement motors</a> deliver crystal-clear visibility during inclement weather, with both manual and electric options featuring corrosion-resistant stainless steel arms and UV-stable blades designed specifically for marine windshield applications.
