The Angler 173 Bay 2012 vs Angler 2100WA I/O 2008 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 Angler 2100WA I/O 2008 measures 21,0 feet overall (2008), giving it roughly 3,8 additional feet of deck space compared to the Angler 173 Bay 2012 at 17,3 feet (2012). At 12 lbs and 25 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.
The power gap is worth calling out. Rated to 210 hp, the Angler 2100WA I/O 2008 has a 95-hp advantage over the Angler 173 Bay 2012's 115-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Angler 2100WA I/O 2008 carries 8 gallons versus 3 gallons in the Angler 173 Bay 2012. 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 Angler 2100WA I/O 2008 is rated for 6 passengers, while the Angler 173 Bay 2012 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Angler 2100WA I/O 2008 could be the deciding factor.
Bottom line: Choose the Angler 2100WA I/O 2008 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 Angler 173 Bay 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
