The Cobia Boats 21 Bay 2016 vs Cobia Boats 235 CC 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.
The power gap is worth calling out. Rated to 300 hp, the Cobia Boats 235 CC 2007 has a 150-hp advantage over the Cobia Boats 21 Bay 2016's 150-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Cobia Boats 21 Bay 2016 carries 55 gallons versus 14 gallons in the Cobia Boats 235 CC 2007.

Bottom line: Choose the Cobia Boats 235 CC 2007 if your priority is putting more people on the water — it handles 7 passengers and at 23,0 ft it has the deck room to back that rating up comfortably. The Cobia Boats 21 Bay 2016 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
