Sea-Dog Line

<h3>About Sea-Dog Line</h3><p>Few names in the marine hardware world carry the same weight as <strong>Sea-Dog Line</strong>. Rooted in the early 1920s and headquartered in Everett, Washington, the company traces its origins to a uniquely inventive sales strategy: its founder, Hans &ldquo;Action&rdquo; Broson Sneve, showcased marine hardware by sailing his wares up and down the Pacific Coast aboard the M.V. Sea-Dog &mdash; a 55-foot cruiser that became the brand&rsquo;s namesake. That spirit of hands-on, on-the-water ingenuity has defined Sea-Dog ever since.</p><p>Today, Sea-Dog Line operates as the Sea-Dog Corporation, a third-generation family business that has expanded from a regional Pacific Coast distributor into a nationally recognized supplier of marine, industrial, and rigging hardware. The company serves everyone from professional shipbuilders to weekend boaters, earning repeat recognition from the National Marine Distributors Association for its supply chain standards and product quality.</p><h3>What Sea-Dog Line Makes</h3><p>Sea-Dog&rsquo;s catalog is remarkably broad. At its core, the brand specializes in providing hardware that must hold up in some of the harshest environments on earth &mdash; saltwater, UV radiation, temperature swings, and constant vibration. To meet those demands, Sea-Dog builds its products from marine-grade materials including 304 and 316 stainless steel, investment-cast bronze, chrome-plated brass, and UV-resistant injection-molded polymers.</p><p>The product lineup spans anchoring and docking hardware, deck fittings, cabin and hatch hardware, chain and rigging components, electrical panels, lighting, plumbing fittings, ventilation equipment, boat hooks, rod holders, and much more. Whether you&rsquo;re outfitting a new build or replacing a worn component, Sea-Dog likely has the part you need.</p><p>Among Sea-Dog&rsquo;s most well-regarded marine electrical and windshield products is their comprehensive lineup of <a href="/7549-sea-dog-line-windshield-wiper-motor-8824">Windshield Wiper Motors</a>. Engineered specifically for the marine environment, these motors feature corrosion-resistant aluminum and stainless steel construction, adjustable sweep angles, and a &ldquo;coast-to-park&rdquo; function that automatically returns the blade to its set position when power is cut &mdash; exactly the kind of thoughtful design detail that sets Sea-Dog apart from generic alternatives.</p><h3>Why Boaters Trust Sea-Dog Line</h3><p>Sea-Dog&rsquo;s longevity in the marine hardware market is no accident. The brand has built its reputation on producing components that align with ABYC (American Boat and Yacht Council) standards, giving boat builders and DIY installers confidence that each part meets recognized safety benchmarks. Products are designed for both recreational and commercial applications, meaning whether you&rsquo;re a weekend angler or a working captain, Sea-Dog hardware is built for your level of use.</p><p>With over a century in the marine industry, an ever-expanding product catalog, and a family-run culture that keeps quality at the forefront, Sea-Dog Line remains one of the most trusted names on the water. Browse the full Sea-Dog lineup to find the right hardware for your vessel.</p>

Thanks

Excellent

Thank you for the quick turnaround from order to shipping the products I ordered

Fast / Easy Straightforward

Product was accurate and shipment was prompt. Could'nt find a better price.

Excellent experience. Cheapest price I could possibly find, reasonable shipping cost (other people tried to charge upwards of $20 where I was only charged $14). Shipping was VERY quick. <br><br>I was slightly weary of ordering from Autoplicity as I had never heard of them before but from here on out they will be the first place I check. Could not be happier. <br><br>There is nothing that could have made this experience more enjoyable for me.

Your the only place that had the parts!

I will be back with you guys

Easy shopping

Your site said if I signed up I could get a discount of some sort. Did not specify the amount. Would like to have that applied.

Fast -regular- shipping even on large items. I was skeptical at first but I am happy and don't regret my purchase!!!
