Both the Crest Crest II Fish 190FC 2012 and the Crest Pro R LE 18 2008 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 Fish 190FC 2012 at 19,5 ft versus Crest Pro R LE 18 2008 at 18,0 ft. At 2 100 lbs and 2 012 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.
Both boats share a closely matched power ceiling - 90 hp for the Crest Crest II Fish 190FC 2012 and 75 hp for the Crest Pro R LE 18 2008. 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 Pro R LE 18 2008 is rated for 10 passengers, while the Crest Crest II Fish 190FC 2012 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Crest Pro R LE 18 2008 could be the deciding factor.
Bottom line: Choose the Crest Pro R LE 18 2008 if your priority is putting more people on the water - it handles 10 passengers and at 18,0 ft it has the deck room to back that rating up comfortably. The Crest Crest II Fish 190FC 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
