When two boats share the same hull type — in this case both the Kayot S260 2005 and the Kayot Z220 2006 are modified vee designs with composite 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?
Size is the most obvious dividing line here. The Kayot S260 2005 measures 25,0 feet overall (2005), giving it roughly 4,0 additional feet of deck space compared to the Kayot Z220 2006 at 21,0 feet (2006). Weight tells a clearer story for trailering families: the Kayot Z220 2006 tips the scales at 395 lbs — 341 lbs less than the Kayot S260 2005 at 54 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 — 320 hp for the Kayot S260 2005 and 320 hp for the Kayot Z220 2006. 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 Kayot S260 2005 carries 94 gallons versus 5 gallons in the Kayot Z220 2006. 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 Kayot S260 2005 is rated for 15 passengers, while the Kayot Z220 2006 caps at 13. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Kayot S260 2005 could be the deciding factor.
Bottom line: Choose the Kayot S260 2005 if your priority is putting more people on the water — it handles 15 passengers and at 25,0 ft it has the deck room to back that rating up comfortably. The Kayot Z220 2006 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 13 that costs less to run day-to-day.
