Both the Scout 245 Abaco 2010 and the Scout 345 XSF 2011 are deep-V designs, both built in fibreglass, 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?
Size is the most obvious dividing line here. The Scout 345 XSF 2011 measures 34,9 feet overall (2011), giving it roughly 10,5 additional feet of deck space compared to the Scout 245 Abaco 2010 at 24,4 feet (2010). Weight tells a clearer story for trailering families: the Scout 345 XSF 2011 tips the scales at 10 800 lbs - 8 200 lbs less than the Scout 245 Abaco 2010 at 2 600 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 700 hp, the Scout 345 XSF 2011 has a 400-hp advantage over the Scout 245 Abaco 2010's 300-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 345 XSF 2011 carries 330 gallons versus 125 gallons in the Scout 245 Abaco 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 345 XSF 2011 is rated for 10 passengers, while the Scout 245 Abaco 2010 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Scout 345 XSF 2011 could be the deciding factor.
Bottom line: Choose the Scout 345 XSF 2011 if your priority is putting more people on the water - it handles 10 passengers and at 34,9 ft it has the deck room to back that rating up comfortably. The Scout 245 Abaco 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 8 that costs less to run day-to-day.
