The Maxum 2100 SD 2007 vs Maxum 2100SC Sport Boat 2006 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 — Maxum 2100 SD 2007 at 21,0 ft versus Maxum 2100SC Sport Boat 2006 at 21,0 ft. Weight tells a clearer story for trailering families: the Maxum 2100 SD 2007 tips the scales at 3 953 lbs — 385 lbs more than the Maxum 2100SC Sport Boat 2006 at 3 568 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 — 300 hp for the Maxum 2100 SD 2007 and 300 hp for the Maxum 2100SC Sport Boat 2006. 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 Maxum 2100 SD 2007 carries 55 gallons versus 5 gallons in the Maxum 2100SC Sport Boat 2006. 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.
