Matching a deep vee Bayliner 180 OB 2011 against a modified vee Bayliner 184 Ski N Fish 2009 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.

On paper these two are close siblings in the size department — Bayliner 180 OB 2011 at 18,0 ft versus Bayliner 184 Ski N Fish 2009 at 18,0 ft. Weight tells a clearer story for trailering families: the Bayliner 184 Ski N Fish 2009 tips the scales at 2 485 lbs — 607 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.

Both boats share a closely matched power ceiling — 125 hp for the Bayliner 180 OB 2011 and 135 hp for the Bayliner 184 Ski N Fish 2009. 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 184 Ski N Fish 2009 carries 28 gallons versus 23 gallons in the Bayliner 180 OB 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 184 Ski N Fish 2009 is rated for 9 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 184 Ski N Fish 2009 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Bayliner 180 OB 2011 comes in at 15 lbs per hp versus 18 lbs per hp for the Bayliner 184 Ski N Fish 2009. The lower the ratio the more explosive the acceleration — meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.
