The Key West 1900 CC 2012 vs Key West Boats 189FS 2021 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.

The power gap is worth calling out. Rated to 150 hp, the Key West 1900 CC 2012 has a 35-hp advantage over the Key West Boats 189FS 2021's 115-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 6 gal and 4 gal — so range won't be a tiebreaker here.

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.
