About this tender
The MasterCraft ProStar is the build we go to when a programme calls for a single-purpose ski boat with tournament pedigree and nothing extraneous designed in. At 6.10m on the waterline with a 2.44m beam, this is a 20-foot direct-drive inboard that has been refined across several generations to do one job - pull a skier through a slalom course with the flattest, most consistent wake available from any production boat. Seven passengers, a fiberglass-composite hull, and an Ilmor V8 driveline sit at the core of the package.
The hull design is the reason the ProStar holds its position in the market. MasterCraft's in-house naval architects have developed a modified-V, partial-step running surface with four tracking fins and proprietary hull rails that deliver what the manufacturer describes as the flattest wakes at any speed and any line length, with minimal spray. That is a claim that tournament results across multiple decades support. The 2020 model year brought a 6.0L MPI Ilmor engine rated at 380 hp as standard, with the 6.2L GDI available as an upgrade at 440 hp or beyond.
On deck, the ProStar's layout is built around the skier and the judge: a floor-mounted ski pylon sits directly ahead of the centre motorbox, gunnel-integrated ski racks clear the cockpit of clutter, and the helm runs a 10-inch touchscreen with Zero Off GPS speed control accurate to a tenth of a mile per hour. The convertible bow - a removable fiberglass lid that converts the open bow to a closed deck - is a feature no other production ski boat currently offers. Modular stern seating folds or removes to keep the aft platform clear when the programme calls for it.
We would put the ProStar alongside the Nautique Ski 200 for any client whose primary requirement is slalom and three-event competition. The MasterCraft build quality holds up - fiberglass-composite construction, CoolFeel vinyl throughout, and Ilmor powertrain warranty coverage of seven years or 1,000 hours on standard engine configurations. For a vessel that will see serious use behind a superyacht or at a private lake facility, that warranty position is meaningful. The 98-litre tank on the 2020 UK-specification model is modest by design; the ProStar is propped and tuned for the 34-36 mph operating band, not open-water range.

Highlights
The four details we'd point out first to a captain who hasn't seen one on the water yet.
The ProStar runs a modified-V partial-step hull with four tracking fins and proprietary hull rails developed by MasterCraft's in-house naval architects. The combination delivers the flattest wakes at competition line lengths and speeds, with minimal spray - a platform on which tournament world records have been set across multiple disciplines.
A removable fiberglass bow lid converts the ProStar from an open-bow configuration with seating for two or three to a fully closed deck. MasterCraft is the only production ski boat manufacturer currently offering this feature, giving the owner two distinct boat layouts without additional canvas or structural compromise.
Standard power on the 2020 ProStar is the Ilmor 6.0L MPI V8 at 380 hp, with the 6.2L GDI at 440 hp available as a factory option. Ilmor backs standard engine configurations with a seven-year, 1,000-hour warranty - the longest powertrain warranty in the inboard towboat segment.
Zero Off is fitted as standard equipment on every ProStar, delivering GPS-based speed control accurate to one-tenth of a mile per hour. The 10-inch touchscreen helm integrates three-event competition software for slalom, tricks, and jump, with stereo and boat management controls consolidated into a single display.
A 98-litre fuel tank on UK-specification 2020 models, along with a dry weight of approximately 1,497 kg, reflects MasterCraft's deliberate design strategy: keep unsprung mass low to maintain flat wakes and predictable pulls across the full range of skier weights and rope lengths.
