When two boats share the same hull type — in this case both the Weld-Craft Jon Boats 2011 and the Weld-Craft RS 56 (17 ft.) 2009 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 RS 56 (17 ft.) 2009 has a 25-hp advantage over the Weld-Craft Jon Boats 2011's 15-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
Bottom line: The Weld-Craft RS 56 (17 ft.) 2009 at 17,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Weld-Craft Jon Boats 2011 at 12,0 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.
