Cobia Boats 172CC 2013 vs Cobia Boats 21 Bay 2016 — Same Brand, Different Boat

The Cobia Boats 172CC 2013 vs Cobia Boats 21 Bay 2016 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 150 hp, the Cobia Boats 21 Bay 2016 has a 60-hp advantage over the Cobia Boats 172CC 2013's 90-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 33 gallons in the Cobia Boats 172CC 2013. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The Cobia Boats 21 Bay 2016 is rated for 6 passengers, while the Cobia Boats 172CC 2013 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Cobia Boats 21 Bay 2016 could be the deciding factor.

Bottom line: Choose the Cobia Boats 21 Bay 2016 if your priority is putting more people on the water — it handles 6 passengers and at 21,0 ft it has the deck room to back that rating up comfortably. The Cobia Boats 172CC 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
