Matching a modified vee Pro-Line 20 Express 2008 against a deep vee Pro-Line 24 Super Sport 2009 means you're likely deciding between two genuinely different on-water experiences. 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 Pro-Line 24 Super Sport 2009 measures 24,0 feet overall (2009), giving it roughly 22,0 additional feet of deck space compared to the Pro-Line 20 Express 2008 at 2,0 feet (2008). Weight tells a clearer story for trailering families: the Pro-Line 20 Express 2008 tips the scales at 275 lbs — 241 lbs more than the Pro-Line 24 Super Sport 2009 at 34 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 300 hp, the Pro-Line 24 Super Sport 2009 has a 100-hp advantage over the Pro-Line 20 Express 2008's 200-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Pro-Line 24 Super Sport 2009 carries 14 gallons versus 7 gallons in the Pro-Line 20 Express 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 Pro-Line 24 Super Sport 2009 is rated for 7 passengers, while the Pro-Line 20 Express 2008 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Pro-Line 24 Super Sport 2009 could be the deciding factor.
Bottom line: Choose the Pro-Line 24 Super Sport 2009 if your priority is putting more people on the water — it handles 7 passengers and at 24,0 ft it has the deck room to back that rating up comfortably. The Pro-Line 20 Express 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
