When two boats share the same hull type — in this case both the Sun Tracker Party Barge 20 2011 and the Sun Tracker Party Barge 22 Sport Fish Regency Edition 2008 are pontoon designs with aluminum construction — the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?

On paper these two are close siblings in the size department — Sun Tracker Party Barge 20 2011 at 21,7 ft versus Sun Tracker Party Barge 22 Sport Fish Regency Edition 2008 at 24,0 ft. Weight tells a clearer story for trailering families: the Sun Tracker Party Barge 20 2011 tips the scales at 1 615 lbs — 1 583 lbs more than the Sun Tracker Party Barge 22 Sport Fish Regency Edition 2008 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.

Both boats share a closely matched power ceiling — 115 hp for the Sun Tracker Party Barge 20 2011 and 135 hp for the Sun Tracker Party Barge 22 Sport Fish Regency Edition 2008. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Both carry nearly identical fuel loads — 42 gal and 45 gal — so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The Sun Tracker Party Barge 22 Sport Fish Regency Edition 2008 is rated for 12 passengers, while the Sun Tracker Party Barge 20 2011 caps at 10. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sun Tracker Party Barge 22 Sport Fish Regency Edition 2008 could be the deciding factor.
