Matching a modified vee MB Sports F21 Tomcat 2010 against a deep vee MB Sports F21 Tomcat 2013 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.
On paper these two are close siblings in the size department — MB Sports F21 Tomcat 2010 at 21,0 ft versus MB Sports F21 Tomcat 2013 at 21,0 ft. At 39 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 350 hp, the MB Sports F21 Tomcat 2013 has a 342-hp advantage over the MB Sports F21 Tomcat 2010'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 65 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 F21 Tomcat 2013 and its 350-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the MB Sports F21 Tomcat 2010 with its 8-hp rating is the more economical daily driver.
