When two boats share the same hull type — in this case both the Kayot S245 I/O 2005 and the Kayot S260 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?
On paper these two are close siblings in the size department — Kayot S245 I/O 2005 at 23,0 ft versus Kayot S260 2006 at 25,0 ft. At 46 lbs and 54 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.
The power gap is worth calling out. Rated to 375 hp, the Kayot S260 2006 has a 55-hp advantage over the Kayot S245 I/O 2005's 320-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 S260 2006 carries 97 gallons versus 9 gallons in the Kayot S245 I/O 2005. 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 2006 is rated for 15 passengers, while the Kayot S245 I/O 2005 caps at 14. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Kayot S260 2006 could be the deciding factor.
Bottom line: Choose the Kayot S260 2006 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 S245 I/O 2005 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 14 that costs less to run day-to-day.
