When two boats share the same hull type — in this case both the Weld-Craft CLT 70 (20 ft.) 2010 and the Weld-Craft Flat Jon Boats 2012 are flat designs with aluminum 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?
The power gap is worth calling out. Rated to 40 hp, the Weld-Craft CLT 70 (20 ft.) 2010 has a 25-hp advantage over the Weld-Craft Flat Jon Boats 2012's 15-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
For family outings this is probably the sharpest distinction between the two. The Weld-Craft CLT 70 (20 ft.) 2010 is rated for 6 passengers, while the Weld-Craft Flat Jon Boats 2012 caps at 3. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Weld-Craft CLT 70 (20 ft.) 2010 could be the deciding factor.
Bottom line: Choose the Weld-Craft CLT 70 (20 ft.) 2010 if your priority is putting more people on the water — it handles 6 passengers and at 2,0 ft it has the deck room to back that rating up comfortably. The Weld-Craft Flat Jon Boats 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 3 that costs less to run day-to-day.
