MasterCraft XT21 Boats for Sale
The MasterCraft XT21 is a versatile twenty-one-foot inboard boat that blends premium performance with family-friendly comfort. Designed as a true crossover model, the XT21 delivers excellent wakes for surfing and boarding along with smooth handling and a balanced ski wake. With its spacious interior, customizable ballast, and refined styling, the XT21 offers the flexibility to enjoy every watersport while maintaining the quality and craftsmanship that define the MasterCraft brand.
The MasterCraft XT21 was introduced as part of the XT Series lineup, which was created to offer high-end crossover capability across a range of sizes. The XT21 quickly became one of the most popular models in the series because it strikes a balance between manageability, interior space, and wake performance. Measuring twenty-one feet and three inches in length, the XT21 is large enough to handle rougher water while still easy to tow, store, and operate.
Built on MasterCraft’s precision-engineered inboard hull, the XT21 was designed to perform across multiple disciplines. With the available Gen 2 Surf System, owners can shape powerful, adjustable surf waves with the touch of a button. The integrated ballast system delivers excellent wakeboarding performance, and at ski speeds the hull produces a smooth, clean wake that works well for recreational slalom skiing. This versatility makes the XT21 a true multi-sport boat that adapts easily to different riders and conditions.
Inside, the XT21 offers a spacious layout that maximizes comfort and functionality. The deep bow design provides additional seating and safety for passengers, while the wraparound cockpit seating creates an inviting social area. Storage compartments are integrated throughout the boat, and the transom walkthrough offers convenient access to the swim platform. Premium upholstery, convertible seating options, and a choice of interior color schemes allow owners to personalize the look and feel.
Technology and convenience features are central to the XT21’s appeal. Many models include digital touchscreen displays for surf and ballast control, premium Klipsch audio systems, and options for heaters, bimini tops, and board racks. Power is provided by Ilmor inboard engines known for their smooth operation, strong torque, and dependable performance. The combination of modern controls, powerful engines, and proven hull design gives the XT21 excellent all-around capability for every kind of water activity.
Over the years, MasterCraft has refined the XT21 with subtle styling updates and technology enhancements to keep it among the best crossover boats in its class. It remains a top choice for families who want premium quality and versatility without moving to a larger footprint. The XT21 continues to represent the core philosophy of the XT Series—delivering the performance of a dedicated towboat with the comfort and adaptability of a family cruiser.
Today, the MasterCraft XT21 stands out as a balanced and capable inboard that performs equally well for surfing, wakeboarding, skiing, and cruising. Its combination of size, luxury, and flexibility has made it a favorite among owners who want all-around performance in a boat that fits nearly any lifestyle.
