Maxum 1800MX Sport Boat 2005 vs Maxum 3700SY Sport Yacht 2005 - Boat Spec Comparison

Q: Which is easier to trailer — the Maxum 1800MX Sport Boat 2005 or the Maxum 3700SY Sport Yacht 2005?

For trailering, the Maxum 3700SY Sport Yacht 2005 has the edge at 178 lbs dry weight versus 1 991 lbs for the Maxum 1800MX Sport Boat 2005.

The Maxum 1800MX Sport Boat 2005 is Coast Guard rated for 5 passengers, while the Maxum 3700SY Sport Yacht 2005 is certified for 12. 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 3700SY Sport Yacht 2005 measures 156" wide, compared to 84" for the Maxum 1800MX Sport Boat 2005. 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 1800MX Sport Boat 2005 or the Maxum 3700SY Sport Yacht 2005?

The Maxum 1800MX Sport Boat 2005 has the bigger tank at 21 gallons, versus 3 gallons on the Maxum 3700SY Sport Yacht 2005. That 18-gallon difference translates to roughly 54–90 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.

Q: Are the Maxum 1800MX Sport Boat 2005 and Maxum 3700SY Sport Yacht 2005 from the same manufacturer?

Yes — both the Maxum 1800MX Sport Boat 2005 and the Maxum 3700SY Sport Yacht 2005 are built by Maxum. That means shared dealer networks, common parts availability, and consistent build quality across the line.

Detailed Evaluation & Buyer Recommendation

Maxum 1800MX Sport Boat 2005 vs Maxum 3700SY Sport Yacht 2005 — Same Brand, Different Boat

The Maxum 1800MX Sport Boat 2005 vs Maxum 3700SY 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.

For family outings this is probably the sharpest distinction between the two. The Maxum 3700SY Sport Yacht 2005 is rated for 12 passengers, while the Maxum 1800MX Sport Boat 2005 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Maxum 3700SY Sport Yacht 2005 could be the deciding factor.

Bottom line: Choose the Maxum 3700SY Sport Yacht 2005 if your priority is putting more people on the water — it handles 12 passengers and at 0,0 ft it has the deck room to back that rating up comfortably. The Maxum 1800MX Sport Boat 2005 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
