The Scout 190 Costa 2007 vs Scout 191 Bay Scout 2013 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 190 Costa 2007 at 19,0 ft versus Scout 191 Bay Scout 2013 at 18,8 ft. At 12 lbs and 13 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 191 Bay Scout 2013 has a 35-hp advantage over the Scout 190 Costa 2007's 115-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 42 gal — so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Scout 191 Bay Scout 2013 is rated for 6 passengers, while the Scout 190 Costa 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 191 Bay Scout 2013 could be the deciding factor.
Bottom line: Choose the Scout 191 Bay Scout 2013 if your priority is putting more people on the water — it handles 6 passengers and at 18,8 ft it has the deck room to back that rating up comfortably. The Scout 190 Costa 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.
