Matching a deep vee Bayliner 315 SB 2011 against a modified vee Bayliner 320 Cruiser 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 2011 at 30,5 ft versus Bayliner 320 Cruiser 2009 at 32,5 ft. Weight tells a clearer story for trailering families: the Bayliner 320 Cruiser 2009 tips the scales at 12 014 lbs — 2 916 lbs less than the Bayliner 315 SB 2011 at 9 098 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 320 Cruiser 2009 has a 40-hp advantage over the Bayliner 315 SB 2011'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 320 Cruiser 2009 carries 16 gallons versus 12 gallons in the Bayliner 315 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 320 Cruiser 2009 is rated for 10 passengers, while the Bayliner 315 SB 2011 caps at 1. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Bayliner 320 Cruiser 2009 could be the deciding factor.
