When two boats share the same hull type — in this case both the Maxum 2100 SC3 2009 and the Maxum 2400 SC3 2008 are deep 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?

Size is the most obvious dividing line here. The Maxum 2400 SC3 2008 measures 24,0 feet overall (2008), giving it roughly 22,0 additional feet of deck space compared to the Maxum 2100 SC3 2009 at 2,0 feet (2009). Weight tells a clearer story for trailering families: the Maxum 2400 SC3 2008 tips the scales at 4 546 lbs — 1 063 lbs less than the Maxum 2100 SC3 2009 at 3 483 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 375 hp, the Maxum 2400 SC3 2008 has a 75-hp advantage over the Maxum 2100 SC3 2009'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 2009 carries 55 gallons versus 7 gallons in the Maxum 2400 SC3 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 Maxum 2400 SC3 2008 is rated for 7 passengers, while the Maxum 2100 SC3 2009 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Maxum 2400 SC3 2008 could be the deciding factor.
