Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.
Size is the most obvious dividing line here. The Sportsman Boats Masters 247 2013 measures 24,3 feet overall (2013), giving it roughly 3,4 additional feet of deck space compared to the Sportsman Boats Discovery 210 2013 at 20,9 feet (2013).

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 Sportsman Boats Masters 247 2013 is rated for 7 passengers, while the Sportsman Boats Discovery 210 2013 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sportsman Boats Masters 247 2013 could be the deciding factor.
Bottom line: Choose the Sportsman Boats Masters 247 2013 if your priority is putting more people on the water - it handles 7 passengers and at 24,3 ft it has the deck room to back that rating up comfortably. The Sportsman Boats Discovery 210 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
