Detailed Evaluation & Buyer Recommendation
Weld-Craft RS 70 (20 ft.) 2009 vs Weldcraft Marine 186 SD 2009 — Same Brand, Different Boat
Matching a flat Weld-Craft RS 70 (20 ft.) 2009 against a deep vee Weldcraft Marine 186 SD 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.
The power gap is worth calling out. Rated to 200 hp, the Weldcraft Marine 186 SD 2009 has a 160-hp advantage over the Weld-Craft RS 70 (20 ft.) 2009's 40-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
Both boats are rated for 6 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
Bottom line: The Weldcraft Marine 186 SD 2009 at 18,5 ft is the right call if deck space, comfort, and entertaining are top of your list. The Weld-Craft RS 70 (20 ft.) 2009 at 2,0 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.
