Maxum 3100 SE 2008 vs Maxum 4200 SY 2007 - Boat Spec Comparison

Q: Which is the larger boat — the Maxum 3100 SE 2008 or the Maxum 4200 SY 2007?

The Maxum 4200 SY 2007 is the longer of the two at 42,0 feet overall. The Maxum 3100 SE 2008 comes in at 3,0 feet, making it roughly 39,0 ft shorter — a meaningful difference in deck room and overall on-water presence.

Q: Which is easier to trailer — the Maxum 3100 SE 2008 or the Maxum 4200 SY 2007?

For trailering, the Maxum 4200 SY 2007 has the edge at 357 lbs dry weight versus 10 765 lbs for the Maxum 3100 SE 2008. 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: How many people can each boat hold?

The Maxum 3100 SE 2008 is Coast Guard rated for 9 passengers, while the Maxum 4200 SY 2007 is certified for 13. 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: Which boat is wider, and does it affect trailering?

The Maxum 4200 SY 2007 measures 166" wide, compared to 126" for the Maxum 3100 SE 2008. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.

Q: Which boat has the larger fuel tank — the Maxum 3100 SE 2008 or the Maxum 4200 SY 2007?

The Maxum 4200 SY 2007 has the bigger tank at 48 gallons, versus 15 gallons on the Maxum 3100 SE 2008. That 33-gallon difference translates to roughly 99–165 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.

Q: Are the Maxum 3100 SE 2008 and Maxum 4200 SY 2007 from the same manufacturer?

Yes — both the Maxum 3100 SE 2008 and the Maxum 4200 SY 2007 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 3100 SE 2008 vs Maxum 4200 SY 2007 — Same Brand, Different Boat

The Maxum 3100 SE 2008 vs Maxum 4200 SY 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 4200 SY 2007 measures 42,0 feet overall (2007), giving it roughly 39,0 additional feet of deck space compared to the Maxum 3100 SE 2008 at 3,0 feet (2008). Weight tells a clearer story for trailering families: the Maxum 3100 SE 2008 tips the scales at 10 765 lbs — 10 408 lbs more than the Maxum 4200 SY 2007 at 357 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.

For family outings this is probably the sharpest distinction between the two. The Maxum 4200 SY 2007 is rated for 13 passengers, while the Maxum 3100 SE 2008 caps at 9. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Maxum 4200 SY 2007 could be the deciding factor.

Bottom line: Choose the Maxum 4200 SY 2007 if your priority is putting more people on the water — it handles 13 passengers and at 42,0 ft it has the deck room to back that rating up comfortably. The Maxum 3100 SE 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 9 that costs less to run day-to-day.
