These include straight adapters for dry locations, pigtail adapters for wet environments, and &ldquo;Y&rdquo; adapters that allow a single dockside receptacle to serve two vessel inlets simultaneously. Each adapter is built to resolve incompatibility between dock outlet and boat inlet configurations without compromising safety or performance.</p><h3>Why Boaters Trust AFI</h3><ul style="list-style:disc"><li>Part of the Marinco Electrical Group, the marine industry&rsquo;s leading electrical brand family</li><li>Products meet ABYC, NMMA, and U.S. Coast Guard standards</li><li>Corrosion-resistant materials and sealed designs rated for wet marine environments</li><li>Wide range of shore power solutions from 15A to 50A and beyond</li><li>Trusted by OEM boat builders and aftermarket boaters worldwide</li></ul><p>Whether you&rsquo;re outfitting a new vessel or replacing worn components on a seasoned cruiser, AFI delivers the dependability that serious boaters demand.</p>
