When two boats share the same hull type — in this case both the Scout 187 Sportfish 2009 and the Scout 190 Costa 2009 are modified 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 — Scout 187 Sportfish 2009 at 18,0 ft versus Scout 190 Costa 2009 at 19,0 ft. Weight tells a clearer story for trailering families: the Scout 187 Sportfish 2009 tips the scales at 151 lbs — 138 lbs more than the Scout 190 Costa 2009 at 13 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 225 hp, the Scout 190 Costa 2009 has a 75-hp advantage over the Scout 187 Sportfish 2009's 150-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 45 gal and 45 gal — so range won't be a tiebreaker here.

Both boats are rated for 6 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.
