The Stabicraft 1720 Matt Watson Signature 2012 is a modified-V design and the Stabicraft 2050 Fisher 2013 is a pontoon design, so you're likely deciding between two noticeably different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.
Size is the most obvious dividing line here. The Stabicraft 2050 Fisher 2013 measures 20,5 feet overall (2013), giving it roughly 3,3 additional feet of deck space compared to the Stabicraft 1720 Matt Watson Signature 2012 at 17,2 feet (2012). At 2 300 lbs and 2 315 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 Stabicraft 2050 Fisher 2013 has a 60-hp advantage over the Stabicraft 1720 Matt Watson Signature 2012'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 Stabicraft 2050 Fisher 2013 carries 40 gallons versus 25 gallons in the Stabicraft 1720 Matt Watson Signature 2012. 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 Stabicraft 2050 Fisher 2013 is rated for 7 passengers, while the Stabicraft 1720 Matt Watson Signature 2012 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Stabicraft 2050 Fisher 2013 could be the deciding factor.
Bottom line: Choose the Stabicraft 2050 Fisher 2013 if your priority is putting more people on the water - it handles 7 passengers and at 20,5 ft it has the deck room to back that rating up comfortably. The Stabicraft 1720 Matt Watson Signature 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
