When two boats share the same hull type — in this case both the Regal 1900 Bowrider 2009 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 1900 Bowrider 2009 at 19,8 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 — 334 lbs less than the Regal 1900 Bowrider 2009 at 31 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 1900 Bowrider 2009 is rated for 8 passengers, while the Regal 2100 RX Bowrider 2012 caps at 1. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Regal 1900 Bowrider 2009 could be the deciding factor.
