When two boats share the same hull type — in this case both the MB Sports B52V23 2008 and the MB Sports F21 Tomcat 2011 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 2008 at 23,0 ft versus MB Sports F21 Tomcat 2011 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 MB Sports F21 Tomcat 2011 tops out at 8 hp. Engine specs for the MB Sports B52V23 2008 aren't listed — confirm with a dealer before selecting an outboard.Both carry nearly identical fuel loads — 64 gal and 64 gal — so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The MB Sports F21 Tomcat 2011 is rated for 14 passengers, while the MB Sports B52V23 2008 caps at 12. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the MB Sports F21 Tomcat 2011 could be the deciding factor.
Bottom line: Choose the MB Sports F21 Tomcat 2011 if your priority is putting more people on the water — it handles 14 passengers and at 21,0 ft it has the deck room to back that rating up comfortably. The MB Sports B52V23 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 12 that costs less to run day-to-day.
