We recommend our Professional Series systems (50 ft. + boat) and Rogue Series for ( < 50 ft. boat). Still, it’s not a hard line as other things can affect the choice such as the number of guests/crew, usage – e.g., lots of streaming to portables and televisions requiring more speed/bandwidth.
We have both our Rogue Pro series and our Professional Series. The professional series is a more demanding installation, with coax cable runs for topside antennas. In contrast, the Rogue series is just the unit installation and a CAT5 network cable run down inside the boat. HP-DB-AC and Tidal Wave have WiFi 5 (802.11ac), whereas the Rogue Series has WiFi 4 (802.11n) and a single antenna only. With multiple antennas and WiFi 5, you have MU-MIMO with a compatible marina Hotspot; you can have multi-user, multi-in/multi-out for numerous simultaneous transmissions (=faster speeds.)
