The Bayliner 300 Cruiser 2007 vs Bayliner GT 2009 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.

Size is the most obvious dividing line here. The Bayliner GT 2009 measures 17,5 feet overall (2009), giving it roughly 14,5 additional feet of deck space compared to the Bayliner 300 Cruiser 2007 at 3,0 feet (2007). Weight tells a clearer story for trailering families: the Bayliner 300 Cruiser 2007 tips the scales at 9 098 lbs — 7 251 lbs more than the Bayliner GT 2009 at 1 847 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 220 hp, the Bayliner 300 Cruiser 2007 has a 85-hp advantage over the Bayliner GT 2009's 135-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 GT 2009 carries 21 gallons versus 12 gallons in the Bayliner 300 Cruiser 2007. 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 GT 2009 is rated for 6 passengers, while the Bayliner 300 Cruiser 2007 caps at 1. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Bayliner GT 2009 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Bayliner GT 2009 comes in at 14 lbs per hp versus 41 lbs per hp for the Bayliner 300 Cruiser 2007. 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.
