When two boats share the same hull type — in this case both the Kayot S245 OB 2007 and the Kayot Z250 2009 are modified 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?

On paper these two are close siblings in the size department — Kayot S245 OB 2007 at 23,0 ft versus Kayot Z250 2009 at 25,0 ft. Weight tells a clearer story for trailering families: the Kayot Z250 2009 tips the scales at 495 lbs — 449 lbs less than the Kayot S245 OB 2007 at 46 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 Z250 2009 has a 150-hp advantage over the Kayot S245 OB 2007's 275-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 Z250 2009 carries 97 gallons versus 9 gallons in the Kayot S245 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.
