When two boats share the same hull type — in this case both the Regal 2100 RX Bowrider 2011 and the Regal 3360 Window Express 2009 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 3360 Window Express 2009 measures 34,7 feet overall (2009), giving it roughly 13,7 additional feet of deck space compared to the Regal 2100 RX Bowrider 2011 at 21,0 feet (2011). Weight tells a clearer story for trailering families: the Regal 3360 Window Express 2009 tips the scales at 1 212 lbs — 1 177 lbs less than the Regal 2100 RX Bowrider 2011 at 35 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 2100 RX Bowrider 2011 is rated for up to 1 people. Passenger data for the Regal 3360 Window Express 2009 wasn't available.
