The Bayliner 249 2006 vs Bayliner 315 SB 2010 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 315 SB 2010 measures 30,5 feet overall (2010), giving it roughly 6,5 additional feet of deck space compared to the Bayliner 249 2006 at 24,0 feet (2006). Weight tells a clearer story for trailering families: the Bayliner 315 SB 2010 tips the scales at 9 098 lbs — 8 699 lbs less than the Bayliner 249 2006 at 399 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 300 hp, the Bayliner 249 2006 has a 40-hp advantage over the Bayliner 315 SB 2010'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 249 2006 carries 78 gallons versus 28 gallons in the Bayliner 315 SB 2010. 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 249 2006 is rated for 11 passengers, while the Bayliner 315 SB 2010 caps at 1. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Bayliner 249 2006 could be the deciding factor.
