Both the Bayliner 255 SB 2011 and the Bayliner 315 Cruiser 2013 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?

Size is the most obvious dividing line here. The Bayliner 315 Cruiser 2013 measures 30,5 feet overall (2013), giving it roughly 5,4 additional feet of deck space compared to the Bayliner 255 SB 2011 at 25,1 feet (2011). Weight tells a clearer story for trailering families: the Bayliner 315 Cruiser 2013 tips the scales at 9 098 lbs - 2 618 lbs less than the Bayliner 255 SB 2011 at 6 480 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 Bayliner 255 SB 2011 carries a rated maximum of 300 hp. Engine data for the Bayliner 315 Cruiser 2013 wasn't available in our records - check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Bayliner 315 Cruiser 2013 carries 120 gallons versus 70 gallons in the Bayliner 255 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 315 Cruiser 2013 is rated for 9 passengers, while the Bayliner 255 SB 2011 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Bayliner 315 Cruiser 2013 could be the deciding factor.
