When two boats share the same hull type — in this case both the MB Sports B52V23 2010 and the MB Sports F21 Tomcat 2012 are modified vee designs with fiberglass 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?
On paper these two are close siblings in the size department — MB Sports B52V23 2010 at 23,0 ft versus MB Sports F21 Tomcat 2012 at 21,0 ft. At 4 lbs and 39 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.
The power gap is worth calling out. Rated to 343 hp, the MB Sports B52V23 2010 has a 335-hp advantage over the MB Sports F21 Tomcat 2012's 8-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 64 gal and 64 gal — so range won't be a tiebreaker here.
Both boats are rated for 14 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 MB Sports B52V23 2010 and its 343-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the MB Sports F21 Tomcat 2012 with its 8-hp rating is the more economical daily driver.
