Both the Scout 187 Dorado 2013 and the Scout 205 Dorado 2008 are modified-V designs, the first built in fibreglass and the second in composite, so 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 Dorado 2013 at 18,6 ft versus Scout 205 Dorado 2008 at 19,0 ft. Weight tells a clearer story for trailering families: the Scout 205 Dorado 2008 tips the scales at 1 920 lbs - 470 lbs less than the Scout 187 Dorado 2013 at 1 450 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 205 Dorado 2008 has a 75-hp advantage over the Scout 187 Dorado 2013'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 205 Dorado 2008 carries 60 gallons versus 44 gallons in the Scout 187 Dorado 2013. 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 205 Dorado 2008 is rated for 8 passengers, while the Scout 187 Dorado 2013 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Scout 205 Dorado 2008 could be the deciding factor.
Bottom line: Choose the Scout 205 Dorado 2008 if your priority is putting more people on the water - it handles 8 passengers and at 19,0 ft it has the deck room to back that rating up comfortably. The Scout 187 Dorado 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
