When two boats share the same hull type — in this case both the Bayliner 184 SF 2010 and the Bayliner 266 Discovery 2013 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 266 Discovery 2013 measures 25,6 feet overall (2013), giving it roughly 7,6 additional feet of deck space compared to the Bayliner 184 SF 2010 at 18,0 feet (2010). Weight tells a clearer story for trailering families: the Bayliner 184 SF 2010 tips the scales at 2 285 lbs — 1 603 lbs more than the Bayliner 266 Discovery 2013 at 682 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 Bayliner 184 SF 2010 carries a rated maximum of 220 hp. Engine data for the Bayliner 266 Discovery 2013 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Bayliner 266 Discovery 2013 carries 81 gallons versus 28 gallons in the Bayliner 184 SF 2010. 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 184 SF 2010 is rated for 8 passengers, while the Bayliner 266 Discovery 2013 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Bayliner 184 SF 2010 could be the deciding factor.
