When two boats share the same hull type — in this case both the Yellowfin 34 2011 and the Yellowfin 36 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?
On paper these two are close siblings in the size department — Yellowfin 34 2011 at 34,7 ft versus Yellowfin 36 2011 at 36,7 ft. At 88 lbs and 95 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 1 400 hp, the Yellowfin 36 2011 has a 350-hp advantage over the Yellowfin 34 2011's 1 050-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 36 2011 carries 51 gallons versus 45 gallons in the Yellowfin 34 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 36 2011 is rated for 11 passengers, while the Yellowfin 34 2011 caps at 10. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Yellowfin 36 2011 could be the deciding factor.
Bottom line: Choose the Yellowfin 36 2011 if your priority is putting more people on the water — it handles 11 passengers and at 36,7 ft it has the deck room to back that rating up comfortably. The Yellowfin 34 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 10 that costs less to run day-to-day.
