When two boats share the same hull type — in this case both the MB Sports F21 Tomcat 2012 and the MB Sports F23 Tomcat 2008 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 F21 Tomcat 2012 at 21,0 ft versus MB Sports F23 Tomcat 2008 at 23,0 ft. At 39 lbs and 41 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 2012 carries a rated maximum of 8 hp. Engine data for the MB Sports F23 Tomcat 2008 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.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 2012 is rated for 14 passengers, while the MB Sports F23 Tomcat 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 2012 could be the deciding factor.
Bottom line: Choose the MB Sports F21 Tomcat 2012 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 F23 Tomcat 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.
