When two boats share the same hull type — in this case both the SouthWind 229 FX 2012 and the SouthWind 2290 L 2010 are tri-hull 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?
On paper these two are close siblings in the size department — SouthWind 229 FX 2012 at 22,8 ft versus SouthWind 2290 L 2010 at 22,8 ft. At 47 lbs and 35 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.
Both boats share a closely matched power ceiling — 115 hp for the SouthWind 229 FX 2012 and 115 hp for the SouthWind 2290 L 2010. 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 SouthWind 2290 L 2010 carries 35 gallons versus 5 gallons in the SouthWind 229 FX 2012. 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 SouthWind 229 FX 2012 is rated for 12 passengers, while the SouthWind 2290 L 2010 caps at 11. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the SouthWind 229 FX 2012 could be the deciding factor.
Bottom line: Choose the SouthWind 229 FX 2012 if your priority is putting more people on the water — it handles 12 passengers and at 22,8 ft it has the deck room to back that rating up comfortably. The SouthWind 2290 L 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 11 that costs less to run day-to-day.
