Whether you like to keep it simple or prefer things more high-tech there is an expansive lineup of boat network connectors. If you're looking for radio access and weather information without the 5G confusion, our collection of kits will offer you just that. DIY the installation of a Wi-Fi powered by LTE systems (2G, 3G, 4G); the Digital Yacht 4G Connect Pro Model Wi-Fi Router is available and easy to install.

Wiring & Accessories

High-tech or traditional, we have boat network accessories and marine power accessories to accompany your new system. When replacing parts on an existing system check your list twice and choose from an array of power cables, audio cables, and video cables. Don't forget to check the connectors, terminators, and converters needed to accompany your new accessories.

We Know Staying Connected is Important!

From weather conditions to radio contact with other vessels, staying connected is paramount to safety on the water. A trustworthy connection can be more than a matter of making sure the XM Radio will belt out a rocking playlist while you're making that catch - communications with other vessels and updated weather information are essential to your safety. Be confident in your setup - from pleasure to essentials - with updated wiring and accessories from Defender.
