The Scout 180 Bay Scout 2007 vs Scout 187 Sportfish 2009 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.
On paper these two are close siblings in the size department — Scout 180 Bay Scout 2007 at 17,0 ft versus Scout 187 Sportfish 2009 at 18,0 ft. Weight tells a clearer story for trailering families: the Scout 187 Sportfish 2009 tips the scales at 151 lbs — 150 lbs less than the Scout 180 Bay Scout 2007 at 1 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 150 hp, the Scout 187 Sportfish 2009 has a 60-hp advantage over the Scout 180 Bay Scout 2007's 90-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 Sportfish 2009 carries 45 gallons versus 34 gallons in the Scout 180 Bay Scout 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 Sportfish 2009 is rated for 6 passengers, while the Scout 180 Bay Scout 2007 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Scout 187 Sportfish 2009 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Scout 180 Bay Scout 2007 comes in at 0 lbs per hp versus 1 lbs per hp for the Scout 187 Sportfish 2009. The lower the ratio the more explosive the acceleration — meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.
Bottom line: Choose the Scout 187 Sportfish 2009 if your priority is putting more people on the water — it handles 6 passengers and at 18,0 ft it has the deck room to back that rating up comfortably. The Scout 180 Bay Scout 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
