When two boats share the same hull type — in this case both the MasterCraft 280 STS 2008 and the MasterCraft X-15 2009 are modified vee designs with fiberglass construction — 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 280 STS 2008 measures 28,0 feet overall (2008), giving it roughly 7,0 additional feet of deck space compared to the MasterCraft X-15 2009 at 21,0 feet (2009). Weight tells a clearer story for trailering families: the MasterCraft X-15 2009 tips the scales at 3 575 lbs — 3 513 lbs less than the MasterCraft 280 STS 2008 at 62 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.

For family outings this is probably the sharpest distinction between the two. The MasterCraft X-15 2009 is rated for 14 passengers, while the MasterCraft 280 STS 2008 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the MasterCraft X-15 2009 could be the deciding factor.
