When two boats share the same hull type — in this case both the Yar-Craft 1785 BT 2012 and the Yar-Craft 209 TFX 2011 are modified vee designs with composite 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 Yar-Craft 209 TFX 2011 measures 20,5 feet overall (2011), giving it roughly 3,1 additional feet of deck space compared to the Yar-Craft 1785 BT 2012 at 17,4 feet (2012). Weight tells a clearer story for trailering families: the Yar-Craft 209 TFX 2011 tips the scales at 2 113 lbs — 738 lbs less than the Yar-Craft 1785 BT 2012 at 1 375 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 250 hp, the Yar-Craft 209 TFX 2011 has a 175-hp advantage over the Yar-Craft 1785 BT 2012's 75-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Yar-Craft 209 TFX 2011 carries 54 gallons versus 36 gallons in the Yar-Craft 1785 BT 2012. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
Both boats are rated for 6 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 Yar-Craft 209 TFX 2011 at 20,5 ft is the right call if deck space, comfort, and entertaining are top of your list. The Yar-Craft 1785 BT 2012 at 17,4 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.
