Detailed Evaluation & Buyer Recommendation

Maxum 3700SY Sport Yacht 2005 vs Maxum 4200 SY 2008 — Same Brand, Different Boat

The Maxum 3700SY Sport Yacht 2005 vs Maxum 4200 SY 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.

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 3700SY Sport Yacht 2005 caps at 12. 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.

Bottom line: Choose the Maxum 4200 SY 2008 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 3700SY Sport Yacht 2005 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 12 that costs less to run day-to-day.
