Both the Bayliner 195 DIS 2010 and the Bayliner 315 SB 2011 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 SB 2011 measures 30,5 feet overall (2011), giving it roughly 11,8 additional feet of deck space compared to the Bayliner 195 DIS 2010 at 18,8 feet (2010). Weight tells a clearer story for trailering families: the Bayliner 315 SB 2011 tips the scales at 9 098 lbs - 6 820 lbs less than the Bayliner 195 DIS 2010 at 2 278 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 260 hp, the Bayliner 315 SB 2011 has a 125-hp advantage over the Bayliner 195 DIS 2010's 135-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 SB 2011 carries 120 gallons versus 23 gallons in the Bayliner 195 DIS 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 315 SB 2011 is rated for 10 passengers, while the Bayliner 195 DIS 2010 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Bayliner 315 SB 2011 could be the deciding factor.
