Meet the 2026 Supra SL550 — a 23.5-foot powerhouse built for those who refuse to compromise between raw performance and refined comfort on the water. Stretching 102 inches wide and driven by the thunderous Indmar Raptor 575 engine pumping out 575 horsepower, this ski and wakeboard boat delivers the kind of pull that turns first-timers into riders and seasoned athletes into believers. Whether you're launching a wakeboarder into the stratosphere or carving a glassy slalom course, the SL550 is engineered to perform at the highest level. Step aboard and you'll immediately notice that Supra loaded this build with every comfort and convenience you could ask for. Cooling seats at the bow and helm keep you refreshed on scorching summer days, while the 4-port heater and interior wash down make shoulder-season sessions just as enjoyable. The electric cooler keeps your drinks cold, the power swim step makes re-entry effortless, and the power folding tower bimini offers shade at the touch of a button. Dual stern thrusters and electric power steering assist make docking this beast surprisingly stress-free, and the docking lights — both bow and tower-mounted — along with underwater and mid-ship lights, mean the fun doesn't have to stop when the sun goes down. Finished in a sleek white hull and available now in Knoxville, this 2026 Supra SL550 is one of the most capable and feature-packed towboats on the market today.

Based on 9 reviews from across the web
The SL550 earns consistent praise from both expert reviewers and owners as one of the stronger all-around watersports boats in its class. Boating Magazine describes the 2026 SL as a benchmark for buyers comparing the very best in the segment. The supercharged Indmar engine delivers confident pull, and the wake and wave tuning system is straightforward enough that riders of all skill levels can get dialed in quickly.
Owners who have come from competing brands note that the SL's build quality holds up well alongside premium alternatives, and several long-time Supra owners keep coming back, with a few now on their fourth or fifth boat. The hull's handling draws particular mention, with owners describing the steering feel as responsive and agile for a boat this size.
Opinions on how the SL stacks up against direct competitors vary from owner to owner. Most feel it runs comfortably with the best in its class; a smaller number consider it a strong but not dominant option in a competitive segment. Either way, the consensus across forums and professional reviews points to a well-rounded, capable boat that suits a wide range of riders and conditions.

We hear this often, and the answer is yes. The wave and wake tuning system is simple to adjust on the fly, so whether you have a beginner or an experienced rider in tow, you can dial in the right setup quickly.
Owners who have come from competing premium brands consistently mention that the SL steers responsively and feels agile for its size, describing it as driving like a proper inboard.
Several of our owners who have owned five or more premium boats from other brands feel the Supra's construction quality is very close to the top names in the segment.
Reviewers and owners alike note strong push and a well-shaped wave. The hull has been refined over multiple model years, and the wave is consistently described as having good energy for surfing.
That is exactly what it is designed for. The adjustable ballast and wave-shaping system let you switch between activities without a lot of fuss, which is one of the things our owners appreciate most about it.
Boating Magazine puts it among the best all-around watersports boats in its size range. A handful of forum owners feel the segment is competitive enough that it is a strong peer rather than a runaway leader, but most agree it holds its own against the best options available.
