When two boats share the same hull type — in this case both the Yellowfin 23 2012 and the Yellowfin 29 2011 are deep 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?
Size is the most obvious dividing line here. The Yellowfin 29 2011 measures 30,9 feet overall (2011), giving it roughly 6,0 additional feet of deck space compared to the Yellowfin 23 2012 at 24,9 feet (2012). At 38 lbs and 74 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 700 hp, the Yellowfin 29 2011 has a 350-hp advantage over the Yellowfin 23 2012's 350-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Yellowfin 29 2011 carries 25 gallons versus 16 gallons in the Yellowfin 23 2012. 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 Yellowfin 29 2011 is rated for 9 passengers, while the Yellowfin 23 2012 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Yellowfin 29 2011 could be the deciding factor.
Bottom line: Choose the Yellowfin 29 2011 if your priority is putting more people on the water — it handles 9 passengers and at 30,9 ft it has the deck room to back that rating up comfortably. The Yellowfin 23 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.
