Winner of an NMMA Innovation Award, Sea Ray's SLX 400, "The Entertainer", combines peak performance, superior comfort, incredible versatility and style, and state-of-the-art technology. The result is more than a boat — it's a premium socializing environment. Every facet of the SLX 400 has been thoughtfully designed for maximum enjoyment, from the inviting cockpit and cabin to the sleek digital helm to the innovative fold-down swim terrace. So you and your friends can experience richer, fuller days on the water.
Mercury-connected performance, Quiet Ride hull, Sea Ray+ remote monitoring. Engineered to be as smart as it is striking.
Turn heads with the revolutionary fold-down swim terrace. This innovative feature generously extends your swim platform and your fun on the water, transforming the stern into a wide stage that meets the waterline.
For overnighting, premium comforts extend to the cabin via a queen-sized bed in the aft section and a forward bunk that converts to form a social gathering area. Up at the bow, find a row of forward touring seats with armrests and additional benches surrounding a stylish bow table that converts into a sunpad.
Built on 65+ years of marine craftsmanship, the SLX 400 is the NMMA Innovation Award-winning flagship of the SLX line. The Sea Ray+ mobile app keeps you connected to your boat from anywhere. Premium materials, ergonomic design, and obsessive attention to detail are standard on every Sea Ray we build.
Watch the SLX 400 from bow to stern, with the fold-down swim terrace, accent-lit cockpit, and digital helm on full display.
Mercury VesselView Mobile keeps you fully connected with your engine through your phone. Customize digital gauges, monitor fuel, and compare performance metrics to optimize speed and efficiency.
Innovative hull design significantly reduces noise and vibration for a smoother, quieter ride. Better fuel efficiency means more time on the water.
