Pro-Line 28 Express 2006 vs Pro-Line 29 Grand Sport 2011 — Same Brand, Different Boat

The Pro-Line 28 Express 2006 vs Pro-Line 29 Grand Sport 2011 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.

On paper these two are close siblings in the size department — Pro-Line 28 Express 2006 at 29,0 ft versus Pro-Line 29 Grand Sport 2011 at 29,3 ft. Weight tells a clearer story for trailering families: the Pro-Line 29 Grand Sport 2011 tips the scales at 631 lbs — 556 lbs less than the Pro-Line 28 Express 2006 at 75 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 Grand Sport 2011 has a 100-hp advantage over the Pro-Line 28 Express 2006's 500-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 Grand Sport 2011 carries 24 gallons versus 2 gallons in the Pro-Line 28 Express 2006. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 8 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

Bottom line: Performance buyers should lean toward the Pro-Line 29 Grand Sport 2011 and its 600-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Pro-Line 28 Express 2006 with its 500-hp rating is the more economical daily driver.

Pro-Line 28 Express 2006 vs Pro-Line 29 Grand Sport 2011 — Common Questions

Which is the larger boat — the Pro-Line 28 Express 2006 or the Pro-Line 29 Grand Sport 2011?
The Pro-Line 29 Grand Sport 2011 is the longer of the two at 29,3 feet overall. The Pro-Line 28 Express 2006 comes in at 29,0 feet, making it roughly 0,3 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Pro-Line 28 Express 2006 or the Pro-Line 29 Grand Sport 2011?
For trailering, the Pro-Line 28 Express 2006 has the edge at 75 lbs dry weight versus 631 lbs for the Pro-Line 29 Grand Sport 2011. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
Which boat can handle a bigger outboard?
The Pro-Line 29 Grand Sport 2011 is rated to a maximum of 600 hp, giving it the larger power ceiling. The Pro-Line 28 Express 2006 tops out at 500 hp. Keep in mind that maximum ratings are just that — matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.
How many people can each boat hold?
The Pro-Line 28 Express 2006 is Coast Guard rated for 8 passengers, while the Pro-Line 29 Grand Sport 2011 is certified for 8. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.
Which boat is wider, and does it affect trailering?
The Pro-Line 28 Express 2006 measures 126" wide, compared to 116" for the Pro-Line 29 Grand Sport 2011. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.
Which boat has the larger fuel tank — the Pro-Line 28 Express 2006 or the Pro-Line 29 Grand Sport 2011?
The Pro-Line 29 Grand Sport 2011 has the bigger tank at 24 gallons, versus 2 gallons on the Pro-Line 28 Express 2006. That 22-gallon difference translates to roughly 66–110 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Pro-Line 28 Express 2006 and Pro-Line 29 Grand Sport 2011 from the same manufacturer?
Yes — both the Pro-Line 28 Express 2006 and the Pro-Line 29 Grand Sport 2011 are built by Pro-Line. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.
