When two boats share the same hull type — in this case both the Regal 2100 RX 2009 and the Regal 52 Sport Coupe 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?

Size is the most obvious dividing line here. The Regal 52 Sport Coupe 2013 measures 53,0 feet overall (2013), giving it roughly 32,0 additional feet of deck space compared to the Regal 2100 RX 2009 at 21,0 feet (2009). Weight tells a clearer story for trailering families: the Regal 52 Sport Coupe 2013 tips the scales at 344 lbs — 310 lbs less than the Regal 2100 RX 2009 at 34 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.

The Regal 52 Sport Coupe 2013 tops out at 87 hp. Engine specs for the Regal 2100 RX 2009 aren't listed — confirm with a dealer before selecting an outboard.Both carry nearly identical fuel loads — 42 gal and 45 gal — so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The Regal 52 Sport Coupe 2013 is rated for 16 passengers, while the Regal 2100 RX 2009 caps at 1. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Regal 52 Sport Coupe 2013 could be the deciding factor.
