The Sun Tracker Party Barge 18 Signature Series 2005 vs Sun Tracker SportFish™ 22 XP3 2022 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 150 hp, the Sun Tracker SportFish™ 22 XP3 2022 has a 75-hp advantage over the Sun Tracker Party Barge 18 Signature Series 2005's 75-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
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.
The Sun Tracker Party Barge 18 Signature Series 2005 is an inflatable design — lighter, easier to store, and quicker to launch from a beach or dock without a slipway. The Sun Tracker SportFish™ 22 XP3 2022 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 SportFish™ 22 XP3 2022 at 24,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Sun Tracker Party Barge 18 Signature Series 2005 at 19,0 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.
