When two boats share the same hull type — in this case both the Regal 2520 FasDeck 2009 and the Regal 42 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 42 Sport Coupe 2013 measures 42,3 feet overall (2013), giving it roughly 17,1 additional feet of deck space compared to the Regal 2520 FasDeck 2009 at 25,3 feet (2009). Weight tells a clearer story for trailering families: the Regal 2520 FasDeck 2009 tips the scales at 485 lbs — 280 lbs more than the Regal 42 Sport Coupe 2013 at 205 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.

For family outings this is probably the sharpest distinction between the two. The Regal 2520 FasDeck 2009 is rated for 14 passengers, while the Regal 42 Sport Coupe 2013 caps at 12. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Regal 2520 FasDeck 2009 could be the deciding factor.
