The Crest 20 2009 vs Crest Crest II 30 2006 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.
Size is the most obvious dividing line here. The Crest Crest II 30 2006 measures 30,0 feet overall (2006), giving it roughly 10,0 additional feet of deck space compared to the Crest 20 2009 at 20,0 feet (2009). Weight tells a clearer story for trailering families: the Crest Crest II 30 2006 tips the scales at 2 830 lbs - 315 lbs less than the Crest 20 2009 at 2 515 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 Crest II 30 2006 has a 35-hp advantage over the Crest 20 2009's 115-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 Crest II 30 2006 is rated for 18 passengers, while the Crest 20 2009 caps at 13. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Crest Crest II 30 2006 could be the deciding factor.
Bottom line: Choose the Crest Crest II 30 2006 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 20 2009 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 13 that costs less to run day-to-day.
