The MasterCraft MasterCraft 300 2010 vs Mastercraft XT22T 2018 comparison sits squarely in the category of decisions where specs alone won't tell the whole story: intended use, storage, and long-term ownership costs all factor in.
Size is the most obvious dividing line here. The MasterCraft MasterCraft 300 2010 measures 33,8 feet overall (2010), giving it roughly 12,7 additional feet of deck space compared to the Mastercraft XT22T 2018 at 21,1 feet (2018). Weight tells a clearer story for trailering families: the MasterCraft MasterCraft 300 2010 tips the scales at 12 500 lbs - 7 225 lbs more than the Mastercraft XT22T 2018 at 5 275 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.
The power gap is worth calling out. Rated to 350 hp, the Mastercraft XT22T 2018 has a 348-hp advantage over the MasterCraft MasterCraft 300 2010's 2-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the MasterCraft MasterCraft 300 2010 carries 200 gallons versus 75 gallons in the Mastercraft XT22T 2018. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
For family outings this is probably the sharpest distinction between the two. The MasterCraft MasterCraft 300 2010 is rated for 10 passengers, while the Mastercraft XT22T 2018 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the MasterCraft MasterCraft 300 2010 could be the deciding factor.
Bottom line: Choose the MasterCraft MasterCraft 300 2010 if your priority is putting more people on the water - it handles 10 passengers and at 33,8 ft it has the deck room to back that rating up comfortably. The Mastercraft XT22T 2018 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
