Both the Parker Boats 2100 Big Bay 2008 and the Parker Boats 2100 Special Edition 2009 are modified-V designs, both built in fibreglass, so 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 2008 at 21,0 ft versus Parker Boats 2100 Special Edition 2009 at 21,0 ft. Weight tells a clearer story for trailering families: the Parker Boats 2100 Big Bay 2008 tips the scales at 2 650 lbs - 200 lbs more than the Parker Boats 2100 Special Edition 2009 at 2 450 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 2008 and 200 hp for the Parker Boats 2100 Special Edition 2009. 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 2009 carries 95 gallons versus 50 gallons in the Parker Boats 2100 Big Bay 2008. 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.
