When two boats share the same hull type — in this case both the Nautica Lowbody 22 2011 and the Nautica RIB 20 Catamaran 2011 are inflatable rigid 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 — Nautica Lowbody 22 2011 at 19,0 ft versus Nautica RIB 20 Catamaran 2011 at 19,5 ft. At 32 lbs and 105 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 power gap is worth calling out. Rated to 260 hp, the Nautica Lowbody 22 2011 has a 145-hp advantage over the Nautica RIB 20 Catamaran 2011's 115-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
Both boats are rated for 16 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.
Bottom line: Performance buyers should lean toward the Nautica Lowbody 22 2011 and its 260-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Nautica RIB 20 Catamaran 2011 with its 115-hp rating is the more economical daily driver.
