The Sun Tracker Fishin Barge 21 Signature Series 2007 vs Sun Tracker Party Barge 20 2010 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 Fishin Barge 21 Signature Series 2007 at 21,0 ft versus Sun Tracker Party Barge 20 2010 at 21,0 ft. At 1 675 lbs and 1 678 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.
The power gap is worth calling out. Rated to 115 hp, the Sun Tracker Party Barge 20 2010 has a 25-hp advantage over the Sun Tracker Fishin Barge 21 Signature Series 2007'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 20 2010 carries 42 gallons versus 3 gallons in the Sun Tracker Fishin Barge 21 Signature Series 2007.

The Sun Tracker Party Barge 20 2010 comes in at 15 lbs per hp versus 19 lbs per hp for the Sun Tracker Fishin Barge 21 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.
