When two boats share the same hull type — in this case both the Bayliner 235 2010 and the Bayliner 266 DIS 2010 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 DIS 2010 measures 25,6 feet overall (2010), giving it roughly 3,1 additional feet of deck space compared to the Bayliner 235 2010 at 22,5 feet (2010). Weight tells a clearer story for trailering families: the Bayliner 266 DIS 2010 tips the scales at 6 354 lbs — 5 979 lbs less than the Bayliner 235 2010 at 375 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 — 300 hp for the Bayliner 235 2010 and 300 hp for the Bayliner 266 DIS 2010. 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 266 DIS 2010 carries 81 gallons versus 5 gallons in the Bayliner 235 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 235 2010 is rated for 11 passengers, while the Bayliner 266 DIS 2010 caps at 1. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Bayliner 235 2010 could be the deciding factor.
