The 2020 Supra SL 400 is a head-turning wake boat that commands attention on the water the moment it leaves the dock. Dressed in a striking Dark Red hull, this 23-foot powerhouse is as bold in appearance as it is in performance — and at $99,999, it represents serious value for a boat of this caliber. Whether you're carving up wakes, pulling tubes, or simply cruising the lake in style, the Supra SL 400 is built to deliver an unforgettable experience every time out. Under the hull lies the heart of this machine: an Indmar 400 Raptor engine pumping out a full 400 horsepower. That kind of power means effortless pull for wakeboarders and surfers alike, with the torque to get riders up quickly and the speed to keep the fun going all day long. The Supra SL platform has long been celebrated in the watersports community for its exceptional wake shaping and on-water feel, and this 2020 model brings all of that proven performance in a well-maintained used package. Located in the Nashville/Gallatin area and ready to find its next home on the water, this Supra SL 400 is a rare opportunity to step into a premium wake boat without the new-boat price tag. Don't let this Dark Red beauty slip away — contact us today to schedule a showing or sea trial and experience the Supra difference for yourself.

The SL 400 holds up well when measured against its competition. Boating Magazine called it one of the best all-around wakeboats in its class, and Power Boating Magazine found it capable across every performance category. We hear similar things from owners who have surfed behind the SL consistently over multiple seasons.
Where the SL genuinely stands out is surf performance and wave-shaping technology. The onboard ballast system, intuitive stern thruster control, and AutoWake system give riders a high degree of customization without a steep learning curve. One owner noted that the SL tracks straight in surf mode, which is a real-world advantage worth knowing. Fit and finish are strong, though some forum comparisons put a competitor or two a small step ahead in that area.
Opinions on how it stacks up overall vary from owner to owner. Most who spend time behind it come away impressed, but a handful of forum voices note that the competitive segment is strong and the SL does not dramatically separate itself from the pack. For buyers who want proven surf and wake performance with solid technology built in, it covers a lot of ground.
We hear consistently strong feedback on surf performance. The combination of the Swell Surf System and standard subfloor ballast gives riders a lot of shaping flexibility, and the boat tracks straight in surf mode without pulling to one side.
The SL uses an intuitive rotating knob on the shifter to control the stern thruster, which owners find easy to dial in compared to button-based systems on some competitors.
It is genuinely strong, though a few owners who have compared it directly to competitors like Nautique rate it just a small notch below in overall fit and finish. Most find it well within the premium range.

It runs on par with strong competitors in the segment, and most owners who spend time on the water with it come away satisfied. A few forum comparisons note the segment is competitive, so there are capable alternatives, but the SL holds its own well.
