About this tender
The MasterCraft XT25 is the build we point owners toward when the superyacht programme calls for serious tow-sport capability without fielding two separate boats. At 7.70m on the waterline, with an 18-person capacity and a 348-litre fuel tank, it is the largest boat in MasterCraft's XT crossover line - built to run a full day of wakeboarding, wakesurfing, and slalom skiing on a single fill. The Vector Drive hull was conceived specifically for tow sports: the engine sits aft, the bow stays clear, and the wake shape can be dialled across three distinct modes without touching a rope.
Propulsion runs through an Ilmor-marinised General Motors block. The 2020 model year that anchors this listing ships with the Ilmor 5.3L unit as standard; later iterations of the platform offer an upgrade path to the 6.0L MPI at 380 hp or the 6.2L GDI at 430 hp, all backed by Ilmor's seven-year, 1,000-hour engine warranty. The drivetrain feeds a four-blade nibral prop through a 2:1 gear ratio V-drive, keeping the prop shaft angle optimised for controlled wake geometry at wakeboard and wakesurf speeds.
The surf system is where the XT25 earns its place in a yacht programme. The Gen 2 Surf System - upgraded to SurfStar on the 2024 redesign - shapes waves via port and starboard tabs that extend up to 26 inches, generating over 1,600 distinct wave profiles without any manual ballast redistribution. The 2024 generation added built-in foiling profiles for left and right-side riders, and standard underwater exhaust that reduces both fumes and noise behind the boat. Total ballast capacity is 2,800 lbs on the 2018-to-2022 platform and rose to 3,200 lbs on the 2024 redesign.
Storage and cockpit volume are what separate the XT25 from the smaller XT models. The midship section delivers 120 cubic feet of usable storage, and the cockpit carries rear-facing seating options that convert between bench and spectator configurations. The dual-screen helm - optional on earlier builds, widely specced on later examples - integrates ballast management, surf system control, audio, and engine diagnostics into a single interface. Klipsch audio with six cabin speakers and four tower speakers comes standard. For a yard tender or chase boat crew running a multi-discipline water-toy programme, the XT25 covers the brief without compromise.

Highlights
The four details we'd point out first to a captain who hasn't seen one on the water yet.
The XT25 is rated for 18 passengers across its 7.70m hull, with an interior beam of 2.20m giving genuine elbow room at full load. Rear-facing seats convert between spectator and bench configurations, and the cockpit is the largest in the XT family. This is the number that makes the XT25 relevant to superyacht tenders programmes where guest headcount on the water matters.
MasterCraft's Vector Drive hull places the Ilmor engine aft in a true V-drive configuration, keeping the centre of gravity low and the bow volume open for passengers. The geometry produces a thick, rampy wakeboard wake, a clean slalom track, and - with ballast loaded - a powerful surf wave. All three modes are available from the same hull without any physical reconfiguration.
Port and starboard wake-shaping tabs extend to 26 inches and, combined with speed and ballast inputs, generate over 1,600 distinct wave profiles. The 2024 SurfStar update added integrated foiling presets for both sides of the boat. Rapid Surf software allows adjustments across seven settings between mellow and steep without stopping the boat or moving weight manually.
The standard 5.3L Ilmor unit provides a freshwater and saltwater-capable powerplant; the 6.0L MPI at 380 hp and the 6.2L GDI at 430 hp are upgrade options. The close-cooled 5.3L GDI is the preferred saltwater specification. All Ilmor units carry a seven-year, 1,000-hour warranty - an unusually long term for a marine inboard engine.
The 92-gallon (348-litre) tank is sized for a full operational day without a refuel stop, which matters when the boat is running a mixed programme of wakesurf sessions at low speed, transit legs, and ski sets at higher throttle. For a yacht programme where the mothership cannot always anchor close to the action, the fuel range is a real working advantage.
