Both the Yellowfin 23 2011 and the Yellowfin 24 Bay 2013 are deep-V designs, both built in fibreglass, so 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 - Yellowfin 23 2011 at 24,9 ft versus Yellowfin 24 Bay 2013 at 24,8 ft. Weight tells a clearer story for trailering families: the Yellowfin 23 2011 tips the scales at 3 800 lbs - 750 lbs more than the Yellowfin 24 Bay 2013 at 3 050 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 - 350 hp for the Yellowfin 23 2011 and 350 hp for the Yellowfin 24 Bay 2013. 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 Yellowfin 23 2011 carries 160 gallons versus 75 gallons in the Yellowfin 24 Bay 2013. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
Both boats are rated for 7 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.
Bottom line: The Yellowfin 23 2011 and Yellowfin 24 Bay 2013 are closely matched on the specs that matter most. Test-ride both on the water you actually use, check current dealer pricing, and factor in long-term service access before you sign.
