When two boats share the same hull type — in this case both the Bayliner 180 OB 2011 and the Bayliner 335 Cruiser 2012 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 335 Cruiser 2012 measures 32,5 feet overall (2012), giving it roughly 14,5 additional feet of deck space compared to the Bayliner 180 OB 2011 at 18,0 feet (2011). Weight tells a clearer story for trailering families: the Bayliner 335 Cruiser 2012 tips the scales at 12 014 lbs — 10 136 lbs less than the Bayliner 180 OB 2011 at 1 878 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 360 hp, the Bayliner 335 Cruiser 2012 has a 235-hp advantage over the Bayliner 180 OB 2011's 125-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 180 OB 2011 carries 23 gallons versus 16 gallons in the Bayliner 335 Cruiser 2012. 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 335 Cruiser 2012 is rated for 10 passengers, while the Bayliner 180 OB 2011 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Bayliner 335 Cruiser 2012 could be the deciding factor.
