Attwood Marine

<h3>About Attwood Marine</h3><p><strong>Attwood Marine</strong> has been a cornerstone of the boating world for well over a century. <a href="/7239-attwood-marine">Founded in 1893</a>, the company began by manufacturing precision underwater hardware and on-deck fittings — rudders, struts, cleats, and lights — and quickly earned a reputation for fine engineering and enduring quality. After World War I, the brand's craftsmanship was so well regarded that legendary boatbuilder Chris-Craft turned to Attwood for brass fittings on their iconic pleasure boats.</p><p>Today, Attwood operates as part of the Navico Group by Brunswick, a global family of industry-leading marine companies, yet it has never lost the boater-first focus that built its name. What distinguishes Attwood from many competitors is their end-to-end philosophy: they design, manufacture, test, and distribute their own products rather than simply sourcing components from third parties. Every item in the Attwood catalog is rigorously tested to meet or exceed U.S. Coast Guard (USCG), American Boat and Yacht Council (ABYC), and CE standards — giving boaters and OEM manufacturers alike the confidence to rely on Attwood gear season after season.</p><h3>A Complete Marine Accessories Ecosystem</h3><p>Attwood's catalog spans an impressively broad range of marine needs. On the comfort and ergonomics side, their <a href="/7239-attwood-marine-seat-pedestal-packages-200926">Seat &amp; Pedestal Packages</a> deliver complete, ready-to-install seating system solutions backed by decades of engineering refinement. For boaters who prefer to build or customize their setup, Attwood's <a href="/200999-pedestals-fixed-mount-attwood-marine-7239">Fixed Mount Pedestals</a> provide a sturdy, reliable foundation engineered for lasting stability on the water.</p><p>When it comes to protecting your hull at the dock, Attwood's <a href="/7239-attwood-marine-fenders-200396">Fenders</a> offer dependable, marine-grade cushioning against docks, pilings, and other vessels — an often-overlooked but essential piece of gear for every boat owner. Getting on and off the boat safely is equally important, and Attwood's <a href="/200179-boarding-ladders-attwood-marine-7239">Boarding Ladders</a> are designed with heavy-duty construction, rated hardware, and user-friendly features to make every entry and exit as secure as possible.</p><p>Beyond these categories, Attwood is also widely recognized for its bilge and aerator pumps, navigation lighting, fuel systems, rod holders, and trailering accessories — making the brand a true one-stop resource for outfitting or refreshing virtually any powerboat, fishing boat, or recreational vessel.</p><h3>Why Boaters Choose Attwood</h3><ul style="list-style:disc"><li><strong>100+ Years of Proven Experience</strong> — A heritage of quality engineering stretching back to 1893.</li><li><strong>Multi-Standard Compliance</strong> — Products tested to USCG, ABYC, and CE standards for safety and performance.</li><li><strong>OEM-Trusted</strong> — A leading supplier to major boat manufacturers across a wide range of product categories.</li><li><strong>Corrosion-Resistant Materials</strong> — Extensive use of 304 and 316 stainless steel, chrome-plated zinc, and marine-grade synthetics built for harsh saltwater environments.</li><li><strong>In-House Engineering</strong> — Advanced prototyping, simulation, and real-world testing ensure reliability before any product reaches the water.</li></ul>

Autoplicity won my loyalty as a customer on two separate counts. Firstly, I am always researching the web for the lowest possible price on an item even while I am in the process of actually ordering it. I had filled in all of my info on their order page and had competed almost everything required concerning making this order. All that was left to do was my clicking of the final 'link' actually confirming the order. At this point I totally stopped and looked elsewhere on the web. A couple of hours later I came back to my computer and was surprised to see an email from Autoplicity asking me why I hadn't fully completed my order and offering me 3% off the purchase price if I would complete it. I immediately finished and submitted the order without hesitation. Secondly, a day or so after I had made the order, I received another email from Autoplicity offering me an additional $5.00 rebate if I wrote a review of my experience with them. Do you think they really want me as a customer? YOU BET!! I like companies that do business like this. They know how to make and keep loyal customers.

They are excellent. They were able to send out my item as early as the next day. I am anticipating my product by early next week. Great!

Seemed fine.

Placed order on Tuesday late afternoon, item shipped next day. One of the fastest turn around times I expereniced online yet. Thank you

Great Price! Great Service!
