When two boats share the same hull type — in this case both the Regal 1900 Bowrider 2008 and the Regal 2100 RS Bowrider 2011 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 2008 at 19,0 ft versus Regal 2100 RS Bowrider 2011 at 21,0 ft. At 31 lbs and 35 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.

The Regal 1900 Bowrider 2008 carries a rated maximum of 270 hp. Engine data for the Regal 2100 RS Bowrider 2011 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Regal 2100 RS Bowrider 2011 carries 42 gallons versus 3 gallons in the Regal 1900 Bowrider 2008. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The Regal 1900 Bowrider 2008 is rated for 8 passengers, while the Regal 2100 RS Bowrider 2011 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 2008 could be the deciding factor.
