Sea Ray took a hard look at how boaters use boats. We entertain, we swim, we tow kids around. When it comes to choosing the most important feature, some of us would start with the power selection — and the SLX 400 will also be available with outboards by the time you read this. Others (you know who) would start with a civilized enclosed head with a shower, and the list goes on: good tunes, lots of seating, easy water access, enough speed to zoom around, a place to eat, and a place to sleep. With the SLX 400, that's a check in every box.
