The Key Largo 174 2006 vs Key Largo 1900 LE 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.

On paper these two are close siblings in the size department — Key Largo 174 2006 at 17,0 ft versus Key Largo 1900 LE 2009 at 18,0 ft. Weight tells a clearer story for trailering families: the Key Largo 174 2006 tips the scales at 1 375 lbs — 1 354 lbs more than the Key Largo 1900 LE 2009 at 21 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 115 hp, the Key Largo 1900 LE 2009 has a 25-hp advantage over the Key Largo 174 2006's 90-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Key Largo 174 2006 carries 35 gallons versus 4 gallons in the Key Largo 1900 LE 2009. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 5 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

At this size, power-to-weight ratio matters more than outright horsepower. The Key Largo 1900 LE 2009 comes in at 0 lbs per hp versus 15 lbs per hp for the Key Largo 174 2006. 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.
