Both the Concept 23 SF Fishing Series 2011 and the Concept 39 CC Series 2013 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 Concept 39 CC Series 2013 measures 39,0 feet overall (2013), giving it roughly 16,0 additional feet of deck space compared to the Concept 23 SF Fishing Series 2011 at 23,0 feet (2011). Weight tells a clearer story for trailering families: the Concept 39 CC Series 2013 tips the scales at 10 500 lbs - 8 200 lbs less than the Concept 23 SF Fishing Series 2011 at 2 300 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 1 050 hp, the Concept 39 CC Series 2013 has a 825-hp advantage over the Concept 23 SF Fishing Series 2011's 225-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Concept 39 CC Series 2013 carries 300 gallons versus 65 gallons in the Concept 23 SF Fishing Series 2011. 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 Concept 39 CC Series 2013 is rated for 11 passengers, while the Concept 23 SF Fishing Series 2011 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Concept 39 CC Series 2013 could be the deciding factor.
Bottom line: Choose the Concept 39 CC Series 2013 if your priority is putting more people on the water - it handles 11 passengers and at 39,0 ft it has the deck room to back that rating up comfortably. The Concept 23 SF Fishing Series 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.
