When two boats share the same hull type — in this case both the Ski Supreme 220SP 2007 and the Ski Supreme V226 2011 are deep 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?
Both boats share a closely matched power ceiling — 340 hp for the Ski Supreme 220SP 2007 and 340 hp for the Ski Supreme V226 2011. 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 Ski Supreme V226 2011 carries 46 gallons versus 34 gallons in the Ski Supreme 220SP 2007. 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 Ski Supreme V226 2011 is rated for 13 passengers, while the Ski Supreme 220SP 2007 caps at 1. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Ski Supreme V226 2011 could be the deciding factor.
Bottom line: Choose the Ski Supreme V226 2011 if your priority is putting more people on the water — it handles 13 passengers and at 22,5 ft it has the deck room to back that rating up comfortably. The Ski Supreme 220SP 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 1 that costs less to run day-to-day.
