The Bayliner 266 Discovery 2012 vs Bayliner 3255 Avanti Sunbridge 1989 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 300 hp, the Bayliner 266 Discovery 2012 has a 40-hp advantage over the Bayliner 3255 Avanti Sunbridge 1989's 260-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 266 Discovery 2012 carries 81 gallons versus 2 gallons in the Bayliner 3255 Avanti Sunbridge 1989. 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 3255 Avanti Sunbridge 1989 is rated for 9 passengers, while the Bayliner 266 Discovery 2012 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Bayliner 3255 Avanti Sunbridge 1989 could be the deciding factor.
