When two boats share the same hull type — in this case both the Parker Boats 2100 Big Bay 2013 and the Parker Boats 2100 Special Edition 2011 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 — Parker Boats 2100 Big Bay 2013 at 21,0 ft versus Parker Boats 2100 Special Edition 2011 at 21,0 ft. Weight tells a clearer story for trailering families: the Parker Boats 2100 Special Edition 2011 tips the scales at 2 635 lbs — 2 370 lbs less than the Parker Boats 2100 Big Bay 2013 at 265 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 — 200 hp for the Parker Boats 2100 Big Bay 2013 and 200 hp for the Parker Boats 2100 Special Edition 2011. 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 Parker Boats 2100 Special Edition 2011 carries 95 gallons versus 44 gallons in the Parker Boats 2100 Big Bay 2013. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 6 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.
