The Maxum 2100 SC3 2007 vs Maxum 4200SY Sport Yacht 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.

Size is the most obvious dividing line here. The Maxum 4200SY Sport Yacht 2006 measures 42,0 feet overall (2006), giving it roughly 40,0 additional feet of deck space compared to the Maxum 2100 SC3 2007 at 2,0 feet (2007). Weight tells a clearer story for trailering families: the Maxum 4200SY Sport Yacht 2006 tips the scales at 288 lbs — 252 lbs less than the Maxum 2100 SC3 2007 at 36 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.

The power gap is worth calling out. Rated to 425 hp, the Maxum 4200SY Sport Yacht 2006 has a 125-hp advantage over the Maxum 2100 SC3 2007's 300-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Maxum 2100 SC3 2007 carries 55 gallons versus 48 gallons in the Maxum 4200SY Sport Yacht 2006. 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 Maxum 4200SY Sport Yacht 2006 is rated for 13 passengers, while the Maxum 2100 SC3 2007 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Maxum 4200SY Sport Yacht 2006 could be the deciding factor.
