Both the Crest III Classic 20 2007 and the Crest Pro Angler LE 20 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 III Classic 20 2007 at 20,0 ft versus Crest Pro Angler LE 20 2008 at 20,0 ft. Weight tells a clearer story for trailering families: the Crest III Classic 20 2007 tips the scales at 2 515 lbs - 240 lbs more than the Crest Pro Angler LE 20 2008 at 2 275 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 Crest III Classic 20 2007 and 100 hp for the Crest Pro Angler LE 20 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 III Classic 20 2007 is rated for 13 passengers, while the Crest Pro Angler LE 20 2008 caps at 11. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Crest III Classic 20 2007 could be the deciding factor.
Bottom line: Choose the Crest III Classic 20 2007 if your priority is putting more people on the water - it handles 13 passengers and at 20,0 ft it has the deck room to back that rating up comfortably. The Crest Pro Angler LE 20 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 11 that costs less to run day-to-day.
