When two boats share the same hull type — in this case both the Regal 2100 Bowrider 2013 and the Regal 2100 RX Bowrider 2012 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 — Regal 2100 Bowrider 2013 at 21,0 ft versus Regal 2100 RX Bowrider 2012 at 21,0 ft. Weight tells a clearer story for trailering families: the Regal 2100 RX Bowrider 2012 tips the scales at 365 lbs — 330 lbs less than the Regal 2100 Bowrider 2013 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.

Both boats are rated for 1 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
