The Pro-Line 27 Sport 2005 vs Pro-Line 29 Super Sport 2005 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.
The power gap is worth calling out. Rated to 600 hp, the Pro-Line 29 Super Sport 2005 has a 200-hp advantage over the Pro-Line 27 Sport 2005's 400-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 2005 carries 192 gallons versus 17 gallons in the Pro-Line 27 Sport 2005. 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 Super Sport 2005 and its 600-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Pro-Line 27 Sport 2005 with its 400-hp rating is the more economical daily driver.
