When two boats share the same hull type — in this case both the Maxum 2400 SC3 2008 and the Maxum 2900 SE 2009 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 21,0 additional feet of deck space compared to the Maxum 2900 SE 2009 at 3,0 feet (2009). Weight tells a clearer story for trailering families: the Maxum 2900 SE 2009 tips the scales at 10 187 lbs — 5 641 lbs less than the Maxum 2400 SC3 2008 at 4 546 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 2900 SE 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 2900 SE 2009 carries 125 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 2900 SE 2009 is rated for 9 passengers, while the Maxum 2400 SC3 2008 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Maxum 2900 SE 2009 could be the deciding factor.
