The Weld-Craft 1752 CDL 2012 is a modified-V design and the Weld-Craft RS 60 (20 ft.) 2008 is a flat-bottom 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.
Both boats share a closely matched power ceiling - 35 hp for the Weld-Craft 1752 CDL 2012 and 40 hp for the Weld-Craft RS 60 (20 ft.) 2008. 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 RS 60 (20 ft.) 2008 at 20,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Weld-Craft 1752 CDL 2012 at 17,0 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.
