The Sun Tracker Party Barge 21 2010 vs Sun Tracker Party Barge 22 Regency Edition 2006 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 — Sun Tracker Party Barge 21 2010 at 21,0 ft versus Sun Tracker Party Barge 22 Regency Edition 2006 at 24,0 ft. Weight tells a clearer story for trailering families: the Sun Tracker Party Barge 22 Regency Edition 2006 tips the scales at 2 121 lbs — 248 lbs less than the Sun Tracker Party Barge 21 2010 at 1 873 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 125 hp, the Sun Tracker Party Barge 22 Regency Edition 2006 has a 35-hp advantage over the Sun Tracker Party Barge 21 2010's 90-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 21 2010 carries 42 gallons versus 3 gallons in the Sun Tracker Party Barge 22 Regency Edition 2006. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

The Sun Tracker Party Barge 22 Regency Edition 2006 comes in at 17 lbs per hp versus 21 lbs per hp for the Sun Tracker Party Barge 21 2010. 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 22 Regency Edition 2006 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 21 2010 is a rigid hull, which typically offers a more confident ride in chop and easier maintenance over the long term.
