Both the Crest Crest II 190 2013 and the Crest II 20 2007 are pontoon 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 - Crest Crest II 190 2013 at 19,5 ft versus Crest II 20 2007 at 20,0 ft. Weight tells a clearer story for trailering families: the Crest II 20 2007 tips the scales at 2 302 lbs - 152 lbs less than the Crest Crest II 190 2013 at 2 150 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 - 90 hp for the Crest Crest II 190 2013 and 100 hp for the Crest II 20 2007. 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.
For family outings this is probably the sharpest distinction between the two. The Crest II 20 2007 is rated for 11 passengers, while the Crest Crest II 190 2013 caps at 10. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Crest II 20 2007 could be the deciding factor.
Bottom line: Choose the Crest II 20 2007 if your priority is putting more people on the water - it handles 11 passengers and at 20,0 ft it has the deck room to back that rating up comfortably. The Crest Crest II 190 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 10 that costs less to run day-to-day.
