When two boats share the same hull type — in this case both the Bayliner 215 2010 and the Bayliner 245 SB 2011 are deep vee designs with fiberglass construction — 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 245 SB 2011 measures 24,1 feet overall (2011), giving it roughly 3,6 additional feet of deck space compared to the Bayliner 215 2010 at 20,5 feet (2010). Weight tells a clearer story for trailering families: the Bayliner 215 2010 tips the scales at 2 838 lbs — 2 292 lbs more than the Bayliner 245 SB 2011 at 546 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.

Both boats share a closely matched power ceiling — 260 hp for the Bayliner 215 2010 and 260 hp for the Bayliner 245 SB 2011. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Fuel capacity breaks the other way: the Bayliner 245 SB 2011 carries 64 gallons versus 37 gallons in the Bayliner 215 2010. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 9 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
