When two boats share the same hull type — in this case both the Excel Boats 1651VSC 2011 and the Excel Boats 1851 SWCC 2011 are modified vee 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 7 000 hp, the Excel Boats 1851 SWCC 2011 has a 6 950-hp advantage over the Excel Boats 1651VSC 2011's 50-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
Both boats are rated for 4 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: Performance buyers should lean toward the Excel Boats 1851 SWCC 2011 and its 7 000-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Excel Boats 1651VSC 2011 with its 50-hp rating is the more economical daily driver.
