Both the Crest 190C4 - C4 Fish 2011 and the Crest III Classic 30 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?
Size is the most obvious dividing line here. The Crest III Classic 30 2007 measures 30,0 feet overall (2007), giving it roughly 10,5 additional feet of deck space compared to the Crest 190C4 - C4 Fish 2011 at 19,5 feet (2011). Weight tells a clearer story for trailering families: the Crest III Classic 30 2007 tips the scales at 3 440 lbs - 1 390 lbs less than the Crest 190C4 - C4 Fish 2011 at 2 050 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 150 hp, the Crest III Classic 30 2007 has a 60-hp advantage over the Crest 190C4 - C4 Fish 2011's 90-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
For family outings this is probably the sharpest distinction between the two. The Crest III Classic 30 2007 is rated for 18 passengers, while the Crest 190C4 - C4 Fish 2011 caps at 10. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Crest III Classic 30 2007 could be the deciding factor.
Bottom line: Choose the Crest III Classic 30 2007 if your priority is putting more people on the water - it handles 18 passengers and at 30,0 ft it has the deck room to back that rating up comfortably. The Crest 190C4 - C4 Fish 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 10 that costs less to run day-to-day.
