When two boats share the same hull type — in this case both the Pro-Line 20 Sport 2013 and the Pro-Line 23 Sport 2010 are modified vee designs with fiberglass construction — 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 — Pro-Line 20 Sport 2013 at 20,5 ft versus Pro-Line 23 Sport 2010 at 23,0 ft. Weight tells a clearer story for trailering families: the Pro-Line 23 Sport 2010 tips the scales at 354 lbs — 328 lbs less than the Pro-Line 20 Sport 2013 at 26 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 300 hp, the Pro-Line 23 Sport 2010 has a 100-hp advantage over the Pro-Line 20 Sport 2013's 200-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Pro-Line 23 Sport 2010 carries 125 gallons versus 7 gallons in the Pro-Line 20 Sport 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 Pro-Line 23 Sport 2010 is rated for 7 passengers, while the Pro-Line 20 Sport 2013 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Pro-Line 23 Sport 2010 could be the deciding factor.
Bottom line: Choose the Pro-Line 23 Sport 2010 if your priority is putting more people on the water — it handles 7 passengers and at 23,0 ft it has the deck room to back that rating up comfortably. The Pro-Line 20 Sport 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.
