Matching a modified vee Yellowfin 21 Hybrid 2011 against a deep vee Yellowfin 29 2011 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 2011 measures 30,9 feet overall (2011), giving it roughly 9,2 additional feet of deck space compared to the Yellowfin 21 Hybrid 2011 at 21,8 feet (2011). Weight tells a clearer story for trailering families: the Yellowfin 21 Hybrid 2011 tips the scales at 2 525 lbs — 2 451 lbs more than the Yellowfin 29 2011 at 74 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 700 hp, the Yellowfin 29 2011 has a 350-hp advantage over the Yellowfin 21 Hybrid 2011'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 21 Hybrid 2011 carries 55 gallons versus 25 gallons in the Yellowfin 29 2011. 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 21 Hybrid 2011 caps at 6. 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 21 Hybrid 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
