The Nautique Crossover Nautique 236 2009 is a modified-V design and the Nautique G25 2013 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 - Nautique Crossover Nautique 236 2009 at 23,0 ft versus Nautique G25 2013 at 25,0 ft. Weight tells a clearer story for trailering families: the Nautique G25 2013 tips the scales at 5 900 lbs - 1 600 lbs less than the Nautique Crossover Nautique 236 2009 at 4 300 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.
Both boats share a closely matched power ceiling - 390 hp for the Nautique Crossover Nautique 236 2009 and 409 hp for the Nautique G25 2013. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Fuel capacity breaks the other way: the Nautique G25 2013 carries 83 gallons versus 51 gallons in the Nautique Crossover Nautique 236 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 Nautique G25 2013 is rated for 19 passengers, while the Nautique Crossover Nautique 236 2009 caps at 16. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Nautique G25 2013 could be the deciding factor.
Bottom line: Choose the Nautique G25 2013 if your priority is putting more people on the water - it handles 19 passengers and at 25,0 ft it has the deck room to back that rating up comfortably. The Nautique Crossover Nautique 236 2009 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 16 that costs less to run day-to-day.
