Matching a deep vee Bayliner 315 SB 2010 against a modified vee Bayliner Discovery 288 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.

On paper these two are close siblings in the size department — Bayliner 315 SB 2010 at 30,5 ft versus Bayliner Discovery 288 2009 at 30,6 ft. Weight tells a clearer story for trailering families: the Bayliner 315 SB 2010 tips the scales at 9 098 lbs — 8 289 lbs more than the Bayliner Discovery 288 2009 at 809 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 300 hp, the Bayliner Discovery 288 2009 has a 40-hp advantage over the Bayliner 315 SB 2010'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 Discovery 288 2009 carries 113 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 Discovery 288 2009 is rated for 10 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 288 2009 could be the deciding factor.
