When two boats share the same hull type — in this case both the Scout 187 Dorado 2010 and the Scout 245 Sportfish 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?

Size is the most obvious dividing line here. The Scout 245 Sportfish 2009 measures 24,0 feet overall (2009), giving it roughly 5,4 additional feet of deck space compared to the Scout 187 Dorado 2010 at 18,6 feet (2010). Weight tells a clearer story for trailering families: the Scout 187 Dorado 2010 tips the scales at 145 lbs — 119 lbs more than the Scout 245 Sportfish 2009 at 26 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 250 hp, the Scout 245 Sportfish 2009 has a 100-hp advantage over the Scout 187 Dorado 2010's 150-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Scout 245 Sportfish 2009 carries 145 gallons versus 44 gallons in the Scout 187 Dorado 2010. 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 Scout 245 Sportfish 2009 is rated for 8 passengers, while the Scout 187 Dorado 2010 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Scout 245 Sportfish 2009 could be the deciding factor.
