Matching a deep vee Yellowfin 29 2012 against a inflatable rigid Yellowfin 40 2013 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.
Size is the most obvious dividing line here. The Yellowfin 29 2012 measures 30,9 feet overall (2012), giving it roughly 26,9 additional feet of deck space compared to the Yellowfin 40 2013 at 4,0 feet (2013). At 74 lbs and 105 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 1 050 hp, the Yellowfin 40 2013 has a 350-hp advantage over the Yellowfin 29 2012's 700-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 2012 carries 25 gallons versus 4 gallons in the Yellowfin 40 2013. 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 40 2013 is rated for 12 passengers, while the Yellowfin 29 2012 caps at 9. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Yellowfin 40 2013 could be the deciding factor.
Bottom line: Choose the Yellowfin 40 2013 if your priority is putting more people on the water — it handles 12 passengers and at 4,0 ft it has the deck room to back that rating up comfortably. The Yellowfin 29 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 9 that costs less to run day-to-day.
