The Century Boats 2350 Dual Console 2008 is a modified-V design and the Century Boats 2400 Center Console 2009 is a deep-V design, so you're likely deciding between two noticeably different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.
On paper these two are close siblings in the size department - Century Boats 2350 Dual Console 2008 at 23,0 ft versus Century Boats 2400 Center Console 2009 at 24,5 ft. Weight tells a clearer story for trailering families: the Century Boats 2400 Center Console 2009 tips the scales at 4 450 lbs - 250 lbs less than the Century Boats 2350 Dual Console 2008 at 4 200 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 350 hp, the Century Boats 2400 Center Console 2009 has a 50-hp advantage over the Century Boats 2350 Dual Console 2008's 300-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Century Boats 2400 Center Console 2009 carries 175 gallons versus 140 gallons in the Century Boats 2350 Dual Console 2008. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
Both boats are rated for 7 passengers - a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
Bottom line: Performance buyers should lean toward the Century Boats 2400 Center Console 2009 and its 350-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Century Boats 2350 Dual Console 2008 with its 300-hp rating is the more economical daily driver.
