The Scout 145 Sportfish 2007 vs Scout 187 Dorado 2012 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.
Size is the most obvious dividing line here. The Scout 187 Dorado 2012 measures 18,6 feet overall (2012), giving it roughly 4,6 additional feet of deck space compared to the Scout 145 Sportfish 2007 at 14,0 feet (2007). At 49 lbs and 145 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.
The power gap is worth calling out. Rated to 150 hp, the Scout 187 Dorado 2012 has a 110-hp advantage over the Scout 145 Sportfish 2007's 40-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 187 Dorado 2012 carries 44 gallons versus 1 gallons in the Scout 145 Sportfish 2007. 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 187 Dorado 2012 is rated for 6 passengers, while the Scout 145 Sportfish 2007 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Scout 187 Dorado 2012 could be the deciding factor.
Bottom line: Choose the Scout 187 Dorado 2012 if your priority is putting more people on the water — it handles 6 passengers and at 18,6 ft it has the deck room to back that rating up comfortably. The Scout 145 Sportfish 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
