Detailed Evaluation & Buyer Recommendation

Maxum 3700 SY 2009 vs Maxum 4200SY Sport Yacht 2005: Same Brand, Different Boat

The Maxum 3700 SY 2009 vs Maxum 4200SY Sport Yacht 2005 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.

The Maxum 3700 SY 2009 carries a rated maximum of 420 hp. Engine data for the Maxum 4200SY Sport Yacht 2005 wasn't available in our records - check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Maxum 4200SY Sport Yacht 2005 carries 480 gallons versus 300 gallons in the Maxum 3700 SY 2009. 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 4200SY Sport Yacht 2005 is rated for 13 passengers, while the Maxum 3700 SY 2009 caps at 11. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Maxum 4200SY Sport Yacht 2005 could be the deciding factor.

Bottom line: Choose the Maxum 4200SY Sport Yacht 2005 if your priority is putting more people on the water - it handles 13 passengers and at 0,0 ft it has the deck room to back that rating up comfortably. The Maxum 3700 SY 2009 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 11 that costs less to run day-to-day.
