The Sun Tracker Party Barge 22 XP3 2004 vs Sun Tracker Party Barge 22 XP3 I/O Regency Edition 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.
On paper these two are close siblings in the size department — Sun Tracker Party Barge 22 XP3 2004 at 22,0 ft versus Sun Tracker Party Barge 22 XP3 I/O Regency Edition 2005 at 25,0 ft. Weight tells a clearer story for trailering families: the Sun Tracker Party Barge 22 XP3 I/O Regency Edition 2005 tips the scales at 3 266 lbs — 3 030 lbs less than the Sun Tracker Party Barge 22 XP3 2004 at 236 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.
Both boats are rated for 14 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.
Both are inflatable designs, which means they pack down for compact storage, can be carried in a bag, and are dramatically lighter than equivalent rigid hulls. The trade-off is setup time and the need to monitor tube pressure regularly.
Bottom line: The Sun Tracker Party Barge 22 XP3 I/O Regency Edition 2005 at 25,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Sun Tracker Party Barge 22 XP3 2004 at 22,0 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.
