Both the Xpress Yukon 18 2010 and the Xpress Yukon 195 2011 are deep-V designs, both built in aluminium, so 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 - Xpress Yukon 18 2010 at 18,0 ft versus Xpress Yukon 195 2011 at 19,5 ft. Weight tells a clearer story for trailering families: the Xpress Yukon 195 2011 tips the scales at 1 673 lbs - 458 lbs less than the Xpress Yukon 18 2010 at 1 215 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.
Both boats share a closely matched power ceiling - 115 hp for the Xpress Yukon 18 2010 and 115 hp for the Xpress Yukon 195 2011. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Both carry nearly identical fuel loads - 30 gal and 30 gal - so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Xpress Yukon 195 2011 is rated for 6 passengers, while the Xpress Yukon 18 2010 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Xpress Yukon 195 2011 could be the deciding factor.
Bottom line: Choose the Xpress Yukon 195 2011 if your priority is putting more people on the water - it handles 6 passengers and at 19,5 ft it has the deck room to back that rating up comfortably. The Xpress Yukon 18 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
