Both the Bayliner 215 Deck 2013 and the Bayliner Discovery 288 2009 are modified-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 Discovery 288 2009 measures 30,6 feet overall (2009), giving it roughly 10,0 additional feet of deck space compared to the Bayliner 215 Deck 2013 at 20,6 feet (2013). Weight tells a clearer story for trailering families: the Bayliner Discovery 288 2009 tips the scales at 8 090 lbs - 4 063 lbs less than the Bayliner 215 Deck 2013 at 4 027 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 80-hp advantage over the Bayliner 215 Deck 2013'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 Discovery 288 2009 carries 113 gallons versus 55 gallons in the Bayliner 215 Deck 2013. 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 215 Deck 2013 is rated for 12 passengers, while the Bayliner Discovery 288 2009 caps at 10. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Bayliner 215 Deck 2013 could be the deciding factor.
