Detailed Evaluation & Buyer Recommendation

Bayliner 180 OB 2011 vs Bayliner 289 Classic 2005 — Same Brand, Different Boat

The Bayliner 180 OB 2011 vs Bayliner 289 Classic 2005 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 Bayliner 180 OB 2011 carries a rated maximum of 125 hp. Engine data for the Bayliner 289 Classic 2005 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Bayliner 289 Classic 2005 carries 102 gallons versus 23 gallons in the Bayliner 180 OB 2011. 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 Bayliner 289 Classic 2005 is rated for 9 passengers, while the Bayliner 180 OB 2011 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Bayliner 289 Classic 2005 could be the deciding factor.

Bottom line: Choose the Bayliner 289 Classic 2005 if your priority is putting more people on the water — it handles 9 passengers and at 0,0 ft it has the deck room to back that rating up comfortably. The Bayliner 180 OB 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.
