The Cobia Boats 194 CC 2006 vs Cobia Boats 21 Bay 2013 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 Cobia Boats 21 Bay 2013 measures 21,1 feet overall (2013), giving it roughly 3,1 additional feet of deck space compared to the Cobia Boats 194 CC 2006 at 18,0 feet (2006).

The power gap is worth calling out. Rated to 200 hp, the Cobia Boats 21 Bay 2013 has a 50-hp advantage over the Cobia Boats 194 CC 2006's 150-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
