The 2026 Supra SL550 is the pinnacle of performance wakeboarding and waterskiing — a 23.5-foot powerhouse built for riders who refuse to settle for anything less than perfect. Powered by the thunderous Indmar Raptor 575, this sleek White hull commands the water with 575 horsepower on tap, ensuring massive, surf-ready wakes and effortless pull for skiers and wakeboarders of every skill level. With an 83-gallon fuel capacity and dual stern thrusters complemented by electric power steering assist, the SL550 delivers both raw performance and refined, confidence-inspiring control every time you leave the dock. Step aboard and you'll immediately notice that Supra has thought of everything. The power folding tower bimini and power swim step make transitions from cruising to riding seamless, while cooling seats at the observer bench and helm keep everyone comfortable even on the hottest summer days. An electric cooler keeps refreshments cold, and the interior wash down ensures cleanup is never a chore. When the sun goes down, underwater lights and underwater mid-ship lights transform the SL550 into a stunning centerpiece on the water, while docking lights fore and tower-mounted make returning to the slip a breeze. The 3-layer non-skid deck, PTM 140 mirror, 4-port heater, and tower-down cover round out a feature set that makes the 2026 Supra SL550 a true four-season, all-day boat ready for Knoxville's best waterways. Whether you're launching a first-timer on the rope or charging through competition-level sets, this is the boat that delivers.

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.

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.
