The Sundance F17 FLX 2006 vs Sundance SV23 2009 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.
Size is the most obvious dividing line here. The Sundance SV23 2009 measures 23,1 feet overall (2009), giving it roughly 7,1 additional feet of deck space compared to the Sundance F17 FLX 2006 at 16,0 feet (2006). Weight tells a clearer story for trailering families: the Sundance F17 FLX 2006 tips the scales at 1 045 lbs — 1 022 lbs more than the Sundance SV23 2009 at 23 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 200 hp, the Sundance SV23 2009 has a 130-hp advantage over the Sundance F17 FLX 2006's 70-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Sundance SV23 2009 carries 72 gallons versus 24 gallons in the Sundance F17 FLX 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 7 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: The Sundance SV23 2009 at 23,1 ft is the right call if deck space, comfort, and entertaining are top of your list. The Sundance F17 FLX 2006 at 16,0 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.
