When two boats share the same hull type — in this case both the MB Sports B52 21 WB 2013 and the MB Sports B52 23 WB 2013 are deep 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 B52 21 WB 2013 at 21,0 ft versus MB Sports B52 23 WB 2013 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.

Both boats share a closely matched power ceiling — 350 hp for the MB Sports B52 21 WB 2013 and 350 hp for the MB Sports B52 23 WB 2013. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Both carry nearly identical fuel loads — 65 gal and 65 gal — so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The MB Sports B52 23 WB 2013 is rated for 16 passengers, while the MB Sports B52 21 WB 2013 caps at 14. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the MB Sports B52 23 WB 2013 could be the deciding factor.
