Both the MasterCraft 280 SST 2008 and the MasterCraft MasterCraft 300 2010 are modified-V designs, both built in fibreglass, so the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?
Size is the most obvious dividing line here. The MasterCraft MasterCraft 300 2010 measures 33,8 feet overall (2010), giving it roughly 5,8 additional feet of deck space compared to the MasterCraft 280 SST 2008 at 28,0 feet (2008). Weight tells a clearer story for trailering families: the MasterCraft MasterCraft 300 2010 tips the scales at 12 500 lbs - 6 300 lbs less than the MasterCraft 280 SST 2008 at 6 200 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 MasterCraft MasterCraft 300 2010 tops out at 2 hp. Engine specs for the MasterCraft 280 SST 2008 aren't listed - confirm with a dealer before selecting an outboard.Fuel capacity breaks the other way: the MasterCraft MasterCraft 300 2010 carries 200 gallons versus 100 gallons in the MasterCraft 280 SST 2008. 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 280 SST 2008 is rated for 15 passengers, while the MasterCraft MasterCraft 300 2010 caps at 10. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the MasterCraft 280 SST 2008 could be the deciding factor.
Bottom line: Choose the MasterCraft 280 SST 2008 if your priority is putting more people on the water - it handles 15 passengers and at 28,0 ft it has the deck room to back that rating up comfortably. The MasterCraft MasterCraft 300 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 10 that costs less to run day-to-day.
