The Sun Tracker Party Barge 20 Signature Series 2007 vs Sun Tracker Party Barge 22 Sport Fish 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.
Size is the most obvious dividing line here. The Sun Tracker Party Barge 22 Sport Fish 2011 measures 24,3 feet overall (2011), giving it roughly 3,3 additional feet of deck space compared to the Sun Tracker Party Barge 20 Signature Series 2007 at 21,0 feet (2007). Weight tells a clearer story for trailering families: the Sun Tracker Party Barge 20 Signature Series 2007 tips the scales at 1 595 lbs — 1 563 lbs more than the Sun Tracker Party Barge 22 Sport Fish 2011 at 32 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 150 hp, the Sun Tracker Party Barge 22 Sport Fish 2011 has a 35-hp advantage over the Sun Tracker Party Barge 20 Signature Series 2007's 115-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Sun Tracker Party Barge 22 Sport Fish 2011 carries 45 gallons versus 3 gallons in the Sun Tracker Party Barge 20 Signature Series 2007. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
Both boats are rated for 12 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.
At this size, power-to-weight ratio matters more than outright horsepower. The Sun Tracker Party Barge 22 Sport Fish 2011 comes in at 0 lbs per hp versus 14 lbs per hp for the Sun Tracker Party Barge 20 Signature Series 2007. The lower the ratio the more explosive the acceleration — meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.
The Sun Tracker Party Barge 20 Signature Series 2007 is an inflatable design — lighter, easier to store, and quicker to launch from a beach or dock without a slipway. The Sun Tracker Party Barge 22 Sport Fish 2011 is a rigid hull, which typically offers a more confident ride in chop and easier maintenance over the long term.
Bottom line: The Sun Tracker Party Barge 22 Sport Fish 2011 at 24,3 ft is the right call if deck space, comfort, and entertaining are top of your list. The Sun Tracker Party Barge 20 Signature Series 2007 at 21,0 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.
