Matching a deep vee Bayliner 315 SB 2010 against a modified vee Bayliner Discovery 192 2009 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.

Size is the most obvious dividing line here. The Bayliner 315 SB 2010 measures 30,5 feet overall (2010), giving it roughly 11,2 additional feet of deck space compared to the Bayliner Discovery 192 2009 at 19,3 feet (2009). Weight tells a clearer story for trailering families: the Bayliner 315 SB 2010 tips the scales at 9 098 lbs — 6 583 lbs more than the Bayliner Discovery 192 2009 at 2 515 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 2010 has a 40-hp advantage over the Bayliner Discovery 192 2009's 220-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 2010 carries 28 gallons versus 23 gallons in the Bayliner Discovery 192 2009. 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 Discovery 192 2009 is rated for 6 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 Discovery 192 2009 could be the deciding factor.
