When two boats share the same hull type — in this case both the Pathfinder 2100 Fusion 2009 and the Pathfinder 2200 2008 are modified vee designs with fiberglass 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 — Pathfinder 2100 Fusion 2009 at 21,0 ft versus Pathfinder 2200 2008 at 21,0 ft. Weight tells a clearer story for trailering families: the Pathfinder 2200 2008 tips the scales at 2 415 lbs — 2 170 lbs less than the Pathfinder 2100 Fusion 2009 at 245 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 — 250 hp for the Pathfinder 2100 Fusion 2009 and 250 hp for the Pathfinder 2200 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. Fuel capacity breaks the other way: the Pathfinder 2100 Fusion 2009 carries 48 gallons versus 6 gallons in the Pathfinder 2200 2008. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
For family outings this is probably the sharpest distinction between the two. The Pathfinder 2200 2008 is rated for 6 passengers, while the Pathfinder 2100 Fusion 2009 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Pathfinder 2200 2008 could be the deciding factor.
Bottom line: Choose the Pathfinder 2200 2008 if your priority is putting more people on the water — it handles 6 passengers and at 21,0 ft it has the deck room to back that rating up comfortably. The Pathfinder 2100 Fusion 2009 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
