The Monterey 233 EX Explorer 2006 vs Monterey 400SY 2009 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 Monterey 400SY 2009 measures 41,0 feet overall (2009), giving it roughly 19,0 additional feet of deck space compared to the Monterey 233 EX Explorer 2006 at 22,0 feet (2006). Weight tells a clearer story for trailering families: the Monterey 400SY 2009 tips the scales at 22 000 lbs - 17 000 lbs less than the Monterey 233 EX Explorer 2006 at 5 000 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 435 hp, the Monterey 400SY 2009 has a 115-hp advantage over the Monterey 233 EX Explorer 2006's 320-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Monterey 400SY 2009 carries 330 gallons versus 57 gallons in the Monterey 233 EX Explorer 2006. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

The Monterey 233 EX Explorer 2006 is rated for up to 6 people. Passenger data for the Monterey 400SY 2009 wasn't available.
