When two boats share the same hull type — in this case both the Yar-Craft 186 FSX 2008 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?
On paper these two are close siblings in the size department — Yar-Craft 186 FSX 2008 at 18,0 ft versus Yar-Craft 209 TFX 2011 at 20,5 ft. Weight tells a clearer story for trailering families: the Yar-Craft 209 TFX 2011 tips the scales at 2 113 lbs — 2 092 lbs less than the Yar-Craft 186 FSX 2008 at 21 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 50-hp advantage over the Yar-Craft 186 FSX 2008's 200-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 186 FSX 2008. 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 Yar-Craft 209 TFX 2011 is rated for 6 passengers, while the Yar-Craft 186 FSX 2008 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Yar-Craft 209 TFX 2011 could be the deciding factor.
Bottom line: Choose the Yar-Craft 209 TFX 2011 if your priority is putting more people on the water — it handles 6 passengers and at 20,5 ft it has the deck room to back that rating up comfortably. The Yar-Craft 186 FSX 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
