You don't need the whole cable and the boat side outlet matches up with the old outlet.

The Smartplugs are definitely good hardware. And for boats with 30A connections, I'd consider them a very, very good upgrade. The 30A NEMA L5-30 connectors aren't adequate for the abuse they take in a marine installation. However, the 50A 125V and 50A 125/250V connectors (NEMA SS-1 and SS-2) are much, much heavier duty and generally perform well unless damaged. For these applications, the Smartplug is less of an upgrade.
