The Bayliner 170 OB 2012 vs Bayliner 242 Classic 2006 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 Bayliner 242 Classic 2006 measures 23,0 feet overall (2006), giving it roughly 5,5 additional feet of deck space compared to the Bayliner 170 OB 2012 at 17,5 feet (2012). Weight tells a clearer story for trailering families: the Bayliner 242 Classic 2006 tips the scales at 5 497 lbs — 3 744 lbs less than the Bayliner 170 OB 2012 at 1 753 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.

The power gap is worth calling out. Rated to 250 hp, the Bayliner 242 Classic 2006 has a 125-hp advantage over the Bayliner 170 OB 2012's 125-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Bayliner 242 Classic 2006 carries 82 gallons versus 21 gallons in the Bayliner 170 OB 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 Bayliner 242 Classic 2006 is rated for 7 passengers, while the Bayliner 170 OB 2012 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Bayliner 242 Classic 2006 could be the deciding factor.
