When two boats share the same hull type — in this case both the Bayliner 245 SB 2011 and the Bayliner 266 Discovery 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?

On paper these two are close siblings in the size department — Bayliner 245 SB 2011 at 24,1 ft versus Bayliner 266 Discovery 2011 at 25,6 ft. Weight tells a clearer story for trailering families: the Bayliner 266 Discovery 2011 tips the scales at 682 lbs — 136 lbs less 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.

The power gap is worth calling out. Rated to 300 hp, the Bayliner 266 Discovery 2011 has a 40-hp advantage over the Bayliner 245 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 266 Discovery 2011 carries 81 gallons versus 64 gallons in the Bayliner 245 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 245 SB 2011 is rated for 9 passengers, while the Bayliner 266 Discovery 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 245 SB 2011 could be the deciding factor.
