Sea-Dog Line

<p>For over a century, Sea-Dog Line has stood as a cornerstone of the marine hardware industry, delivering innovative solutions that meet the demanding needs of recreational and commercial boaters. 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. Their <a href="/7549-sea-dog-line-electric-horns-200351">electric horns</a> include the popular MaxBlast line, which passed rigorous 600-hour salt spray testing while meeting US Coast Guard COLREGS and ABYC standards for audible warning devices. For fuel and water system integrity, Sea-Dog's <a href="/7549-sea-dog-line-deck-fills-200307">deck fills</a> provide secure, leak-free access points constructed from durable stainless steel with snap-in designs that resist corrosion in saltwater environments.</p><p>When maneuvering in low-light conditions, Sea-Dog's <a href="/7549-sea-dog-line-docking-lights-200335">docking lights</a> offer bright LED illumination with minimal power draw, featuring injection-molded housings that withstand impacts and temperature extremes. Proper airflow is essential for preventing moisture buildup below deck, and Sea-Dog's <a href="/7549-sea-dog-line-hose-and-cowl-vents-200534">hose and cowl vents</a> deliver reliable ventilation with low-profile designs that include snap-in deck plates for bilge applications or dorade box compatibility for cabin use.

Great service

Everything went well ordering

Very easy process. Not all sites this easy to navigate. Thank you!

Lowest price and free shipping life is good

Good selection of auto parts, great parts, and really fast shipping. Honestly I don't understand why there are so many negative reviews for this company. I received no compensation for this review, will certainly use Autoplicity again.

Great price and nice shipping discount coupon

ordering was easy

Went well overall. I hope these fit my truck which are larger than the generic applications that fit 25 other vehicles except my truck. Every application I have received so far are about 2/3eds the size they should be for a truck application. Hope I won't

Quick and easy.great price

very happy with Autoplicity.com, good price and they had the shocks I needed, fast shipping. I will be doing more shopping at autoplicity.com. Thanks Mark

Lowest prices around the web and excellent customer service. The only real issue was the wait between placing the order and when it was shipped. Took 4 days but I chalk that up to the large amount of business they due to their prices being so competitive. For the lowest prices that I've seen I didn't mind waiting a bit longer!

Adequate.

fast and easy competitive pricing

hopefully receive by weekend

very easy
