When two boats share the same hull type — in this case both the Maxum 1900 SR3 2009 and the Maxum 3700 SY 2009 are modified vee designs with fiberglass construction — the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?

Size is the most obvious dividing line here. The Maxum 3700 SY 2009 measures 37,0 feet overall (2009), giving it roughly 18,0 additional feet of deck space compared to the Maxum 1900 SR3 2009 at 19,0 feet (2009). Weight tells a clearer story for trailering families: the Maxum 1900 SR3 2009 tips the scales at 2 987 lbs — 1 055 lbs more than the Maxum 3700 SY 2009 at 1 932 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 power gap is worth calling out. Rated to 420 hp, the Maxum 3700 SY 2009 has a 160-hp advantage over the Maxum 1900 SR3 2009's 260-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Maxum 1900 SR3 2009 carries 35 gallons versus 3 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 3700 SY 2009 is rated for 11 passengers, while the Maxum 1900 SR3 2009 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Maxum 3700 SY 2009 could be the deciding factor.
