About the MasterCraft XT21
The MasterCraft XT21 was part of the XT series, created to give owners premium crossover capability in a range of sizes. It quickly became a favorite because it balances manageable size, interior space and wake performance, and today it's a popular pick on the used market for families who want a true multi sport boat.
Behind the boat, factory ballast and MasterCraft's surf system build an adjustable surf wave, and the hull throws solid wakeboard wakes. At ski speeds it produces a smooth, clean wake that works well for recreational slalom. Features vary by year and options, but most XT21s include a touchscreen dash, a folding tower with board racks, quality audio and comfortable wraparound seating.
What to Check When Buying a Used XT21
- Confirm which surf system and engine the boat has, since both varied by year
- Make sure the touchscreen and every surf and ballast function work properly
- Run the ballast system to confirm each pump fills and drains
- Inspect the tower, hinges and any tower speakers
- Ask for service records, especially on higher hour engines
For families who want one boat that can surf, wakeboard and ski well, the XT21 is a versatile used option with MasterCraft quality.
