Both the Bayliner 210 Deck 2013 and the Bayliner Discovery 215 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?

On paper these two are close siblings in the size department - Bayliner 210 Deck 2013 at 20,6 ft versus Bayliner Discovery 215 2009 at 20,8 ft. Weight tells a clearer story for trailering families: the Bayliner 210 Deck 2013 tips the scales at 3 468 lbs - 683 lbs more than the Bayliner Discovery 215 2009 at 2 785 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 Discovery 215 2009 has a 110-hp advantage over the Bayliner 210 Deck 2013's 150-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 210 Deck 2013 carries 55 gallons versus 37 gallons in the Bayliner Discovery 215 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 210 Deck 2013 is rated for 12 passengers, while the Bayliner Discovery 215 2009 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Bayliner 210 Deck 2013 could be the deciding factor.
