Both the Bayliner 285 SB 2011 and the Bayliner 315 Cruiser 2012 are deep-V designs, both built in fibreglass, so the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?

On paper these two are close siblings in the size department - Bayliner 285 SB 2011 at 28,6 ft versus Bayliner 315 Cruiser 2012 at 30,5 ft. Weight tells a clearer story for trailering families: the Bayliner 315 Cruiser 2012 tips the scales at 9 098 lbs - 1 042 lbs less than the Bayliner 285 SB 2011 at 8 056 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 380 hp, the Bayliner 285 SB 2011 has a 120-hp advantage over the Bayliner 315 Cruiser 2012'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 315 Cruiser 2012 carries 120 gallons versus 89 gallons in the Bayliner 285 SB 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 285 SB 2011 is rated for 10 passengers, while the Bayliner 315 Cruiser 2012 caps at 9. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Bayliner 285 SB 2011 could be the deciding factor.
