When two boats share the same hull type — in this case both the Key Largo 150 2008 and the Key Largo 1900 LE 2011 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?

On paper these two are close siblings in the size department — Key Largo 150 2008 at 15,0 ft versus Key Largo 1900 LE 2011 at 18,0 ft. Weight tells a clearer story for trailering families: the Key Largo 150 2008 tips the scales at 875 lbs — 854 lbs more than the Key Largo 1900 LE 2011 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 2011 has a 55-hp advantage over the Key Largo 150 2008's 60-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 2 gal and 4 gal — so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The Key Largo 1900 LE 2011 is rated for 5 passengers, while the Key Largo 150 2008 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Key Largo 1900 LE 2011 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Key Largo 1900 LE 2011 comes in at 0 lbs per hp versus 15 lbs per hp for the Key Largo 150 2008. 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.
