Matching a modified vee Pro-Line 23 Bay 2010 against a deep vee Pro-Line 29 Super Sport 2008 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 29 Super Sport 2008 measures 28,0 feet overall (2008), giving it roughly 5,0 additional feet of deck space compared to the Pro-Line 23 Bay 2010 at 23,0 feet (2010). Weight tells a clearer story for trailering families: the Pro-Line 23 Bay 2010 tips the scales at 345 lbs — 292 lbs more than the Pro-Line 29 Super Sport 2008 at 53 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 600 hp, the Pro-Line 29 Super Sport 2008 has a 300-hp advantage over the Pro-Line 23 Bay 2010's 300-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 29 Super Sport 2008 carries 192 gallons versus 8 gallons in the Pro-Line 23 Bay 2010. 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 29 Super Sport 2008 is rated for 8 passengers, while the Pro-Line 23 Bay 2010 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Pro-Line 29 Super Sport 2008 could be the deciding factor.
Bottom line: Choose the Pro-Line 29 Super Sport 2008 if your priority is putting more people on the water — it handles 8 passengers and at 28,0 ft it has the deck room to back that rating up comfortably. The Pro-Line 23 Bay 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.
