The Crest Crest Sport Model 20 2004 vs Crest Pro R 18 2007 comparison sits squarely in the category of decisions where specs alone won't tell the whole story: intended use, storage, and long-term ownership costs all factor in.
On paper these two are close siblings in the size department - Crest Crest Sport Model 20 2004 at 20,0 ft versus Crest Pro R 18 2007 at 18,0 ft. Weight tells a clearer story for trailering families: the Crest Pro R 18 2007 tips the scales at 2 012 lbs - 287 lbs less than the Crest Crest Sport Model 20 2004 at 1 725 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 - 75 hp for the Crest Crest Sport Model 20 2004 and 75 hp for the Crest Pro R 18 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 Crest Sport Model 20 2004 is rated for 11 passengers, while the Crest Pro R 18 2007 caps at 10. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Crest Crest Sport Model 20 2004 could be the deciding factor.
Bottom line: Choose the Crest Crest Sport Model 20 2004 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 Pro R 18 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 10 that costs less to run day-to-day.
