The Maxum 2100 SC3 2008 is a deep-V design and the Maxum 4200 SY 2008 is a modified-V design, so you're likely deciding between two noticeably different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.

Size is the most obvious dividing line here. The Maxum 4200 SY 2008 measures 42,0 feet overall (2008), giving it roughly 22,0 additional feet of deck space compared to the Maxum 2100 SC3 2008 at 20,0 feet (2008). Weight tells a clearer story for trailering families: the Maxum 4200 SY 2008 tips the scales at 27 392 lbs - 23 909 lbs less than the Maxum 2100 SC3 2008 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 Maxum 2100 SC3 2008 carries a rated maximum of 300 hp. Engine data for the Maxum 4200 SY 2008 wasn't available in our records - check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Maxum 4200 SY 2008 carries 480 gallons versus 55 gallons in the Maxum 2100 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 4200 SY 2008 is rated for 13 passengers, while the Maxum 2100 SC3 2008 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Maxum 4200 SY 2008 could be the deciding factor.
