Matching a modified vee Weld-Craft 1648 VCDS 2012 against a flat Weld-Craft UVCDS 36 (12 ft.) 2009 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.
Both boats share a closely matched power ceiling — 35 hp for the Weld-Craft 1648 VCDS 2012 and 15 hp for the Weld-Craft UVCDS 36 (12 ft.) 2009. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup.
Bottom line: The Weld-Craft 1648 VCDS 2012 at 16,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Weld-Craft UVCDS 36 (12 ft.) 2009 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.
