Maxum 1800 MX 2008 vs Maxum 3700SY Sport Yacht 2006 — Same Brand, Different Boat

The Maxum 1800 MX 2008 vs Maxum 3700SY Sport Yacht 2006 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 3700SY Sport Yacht 2006 measures 37,0 feet overall (2006), giving it roughly 20,0 additional feet of deck space compared to the Maxum 1800 MX 2008 at 17,0 feet (2008). Weight tells a clearer story for trailering families: the Maxum 1800 MX 2008 tips the scales at 1 991 lbs — 1 813 lbs more than the Maxum 3700SY Sport Yacht 2006 at 178 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 3700SY Sport Yacht 2006 tops out at 370 hp. Engine specs for the Maxum 1800 MX 2008 aren't listed — confirm with a dealer before selecting an outboard.Fuel capacity breaks the other way: the Maxum 1800 MX 2008 carries 21 gallons versus 3 gallons in the Maxum 3700SY Sport Yacht 2006. 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 3700SY Sport Yacht 2006 is rated for 11 passengers, while the Maxum 1800 MX 2008 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 2006 could be the deciding factor.

Bottom line: Choose the Maxum 3700SY Sport Yacht 2006 if your priority is putting more people on the water — it handles 11 passengers and at 37,0 ft it has the deck room to back that rating up comfortably. The Maxum 1800 MX 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.

Maxum 1800 MX 2008 vs Maxum 3700SY Sport Yacht 2006 — Common Questions

Which is the larger boat — the Maxum 1800 MX 2008 or the Maxum 3700SY Sport Yacht 2006?
The Maxum 3700SY Sport Yacht 2006 is the longer of the two at 37,0 feet overall. The Maxum 1800 MX 2008 comes in at 17,0 feet, making it roughly 20,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Maxum 1800 MX 2008 or the Maxum 3700SY Sport Yacht 2006?
For trailering, the Maxum 3700SY Sport Yacht 2006 has the edge at 178 lbs dry weight versus 1 991 lbs for the Maxum 1800 MX 2008. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows.

How many people can each boat hold?
The Maxum 1800 MX 2008 is Coast Guard rated for 5 passengers, while the Maxum 3700SY Sport Yacht 2006 is certified for 11. 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.

The Maxum 3700SY Sport Yacht 2006 measures 156" wide, compared to 84" for the Maxum 1800 MX 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.

The Maxum 1800 MX 2008 has the bigger tank at 21 gallons, versus 3 gallons on the Maxum 3700SY Sport Yacht 2006. That 18-gallon difference translates to roughly 54–90 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
