The Maxum 1800MX Sport Boat 2006 vs Maxum 2100 SC3 2007 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 1800MX Sport Boat 2006 measures 17,0 feet overall (2006), giving it roughly 15,0 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 1800MX Sport Boat 2006 tips the scales at 1 991 lbs — 1 955 lbs more 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 300 hp, the Maxum 2100 SC3 2007 has a 165-hp advantage over the Maxum 1800MX Sport Boat 2006's 135-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 21 gallons in the Maxum 1800MX Sport Boat 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 2100 SC3 2007 is rated for 6 passengers, while the Maxum 1800MX Sport Boat 2006 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Maxum 2100 SC3 2007 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Maxum 2100 SC3 2007 comes in at 0 lbs per hp versus 15 lbs per hp for the Maxum 1800MX Sport Boat 2006. The lower the ratio the more explosive the acceleration — meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.
Bottom line: Choose the Maxum 2100 SC3 2007 if your priority is putting more people on the water — it handles 6 passengers and at 2,0 ft it has the deck room to back that rating up comfortably. The Maxum 1800MX Sport Boat 2006 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
