When two boats share the same hull type — in this case both the Bayliner 195 2010 and the Bayliner 315 SB 2010 are deep vee designs with fiberglass construction — 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 2010 measures 30,5 feet overall (2010), giving it roughly 11,5 additional feet of deck space compared to the Bayliner 195 2010 at 19,0 feet (2010). Weight tells a clearer story for trailering families: the Bayliner 315 SB 2010 tips the scales at 9 098 lbs — 8 796 lbs less than the Bayliner 195 2010 at 302 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.

Both boats share a closely matched power ceiling — 260 hp for the Bayliner 195 2010 and 260 hp for the Bayliner 315 SB 2010. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Fuel capacity breaks the other way: the Bayliner 195 2010 carries 35 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 195 2010 is rated for 9 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 195 2010 could be the deciding factor.
