The Weld-Craft 1652 DD Econo 2012 is a modified-V design and the Weldcraft Marine 20 2009 is a deep-V 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 Weldcraft Marine 20 2009 measures 20,0 feet overall (2009), giving it roughly 4,0 additional feet of deck space compared to the Weld-Craft 1652 DD Econo 2012 at 16,0 feet (2012). Weight tells a clearer story for trailering families: the Weldcraft Marine 20 2009 tips the scales at 2 500 lbs - 1 800 lbs less than the Weld-Craft 1652 DD Econo 2012 at 700 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 Weld-Craft 1652 DD Econo 2012 carries a rated maximum of 80 hp. Engine data for the Weldcraft Marine 20 2009 wasn't available in our records - check the manufacturer's spec sheet before sizing a motor.
For family outings this is probably the sharpest distinction between the two. The Weld-Craft 1652 DD Econo 2012 is rated for 5 passengers, while the Weldcraft Marine 20 2009 caps at 1. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Weld-Craft 1652 DD Econo 2012 could be the deciding factor.
Bottom line: Choose the Weld-Craft 1652 DD Econo 2012 if your priority is putting more people on the water - it handles 5 passengers and at 16,0 ft it has the deck room to back that rating up comfortably. The Weldcraft Marine 20 2009 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 1 that costs less to run day-to-day.
