When two boats share the same hull type — in this case both the Kayot S225 I/O 2005 and the Kayot V220i OB 2007 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?

On paper these two are close siblings in the size department — Kayot S225 I/O 2005 at 22,0 ft versus Kayot V220i OB 2007 at 22,0 ft. Weight tells a clearer story for trailering families: the Kayot V220i OB 2007 tips the scales at 406 lbs — 364 lbs less than the Kayot S225 I/O 2005 at 42 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 425 hp, the Kayot S225 I/O 2005 has a 175-hp advantage over the Kayot V220i OB 2007's 250-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Kayot S225 I/O 2005 carries 57 gallons versus 45 gallons in the Kayot V220i OB 2007. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 14 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.
