Maxum 2100SD Sport Deck 2006 vs Maxum 2400 SR3 2008 - Boat Spec Comparison

Q: Which is the larger boat — the Maxum 2100SD Sport Deck 2006 or the Maxum 2400 SR3 2008?

The Maxum 2400 SR3 2008 is the longer of the two at 24,0 feet overall. The Maxum 2100SD Sport Deck 2006 comes in at 21,0 feet, making it roughly 3,0 ft shorter — a meaningful difference in deck room and overall on-water presence.

Q: Which is easier to trailer — the Maxum 2100SD Sport Deck 2006 or the Maxum 2400 SR3 2008?

For trailering, the Maxum 2400 SR3 2008 has the edge at 437 lbs dry weight versus 3 928 lbs for the Maxum 2100SD Sport Deck 2006. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.

Q: Which boat can handle a bigger outboard?

The Maxum 2400 SR3 2008 is rated to a maximum of 375 hp, giving it the larger power ceiling. The Maxum 2100SD Sport Deck 2006 tops out at 300 hp. Keep in mind that maximum ratings are just that — matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.

Q: How many people can each boat hold?

The Maxum 2100SD Sport Deck 2006 is Coast Guard rated for 1 passengers, while the Maxum 2400 SR3 2008 is certified for 7. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.

Q: Do these boats require an oversize trailer permit to tow on US highways?

Both the Maxum 2100SD Sport Deck 2006 and Maxum 2400 SR3 2008 share an 8 ft. 6 in. (2.59 m) beam — meaning both sit right at the 8’6" threshold that most US states use for standard-width loads. In most states you can tow at that width without a special permit, but regulations vary. Always check the rules for your state and any states you'll be passing through before your first long haul.

Q: Which boat has the larger fuel tank — the Maxum 2100SD Sport Deck 2006 or the Maxum 2400 SR3 2008?

The Maxum 2100SD Sport Deck 2006 has the bigger tank at 55 gallons, versus 7 gallons on the Maxum 2400 SR3 2008. That 48-gallon difference translates to roughly 144–240 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.

Q: Are the Maxum 2100SD Sport Deck 2006 and Maxum 2400 SR3 2008 from the same manufacturer?

Yes — both the Maxum 2100SD Sport Deck 2006 and the Maxum 2400 SR3 2008 are built by Maxum. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.

Detailed Evaluation & Buyer Recommendation

Maxum 2100SD Sport Deck 2006 vs Maxum 2400 SR3 2008 — Same Brand, Different Boat

The Maxum 2100SD Sport Deck 2006 vs Maxum 2400 SR3 2008 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 2100SD Sport Deck 2006 at 21,0 ft versus Maxum 2400 SR3 2008 at 24,0 ft. Weight tells a clearer story for trailering families: the Maxum 2100SD Sport Deck 2006 tips the scales at 3 928 lbs — 3 491 lbs more than the Maxum 2400 SR3 2008 at 437 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 SR3 2008 has a 75-hp advantage over the Maxum 2100SD Sport Deck 2006'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 2100SD Sport Deck 2006 carries 55 gallons versus 7 gallons in the Maxum 2400 SR3 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 SR3 2008 is rated for 7 passengers, while the Maxum 2100SD Sport Deck 2006 caps at 1. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Maxum 2400 SR3 2008 could be the deciding factor.

Bottom line: Choose the Maxum 2400 SR3 2008 if your priority is putting more people on the water — it handles 7 passengers and at 24,0 ft it has the deck room to back that rating up comfortably. The Maxum 2100SD Sport Deck 2006 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 1 that costs less to run day-to-day.
