When two boats share the same hull type — in this case both the Nautica RIB 17 Widebody 2011 and the Nautica RIB 19 Widebody 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 RIB 17 Widebody 2011 at 16,3 ft versus Nautica RIB 19 Widebody 2011 at 18,7 ft. Weight tells a clearer story for trailering families: the Nautica RIB 17 Widebody 2011 tips the scales at 849 lbs — 613 lbs more than the Nautica RIB 19 Widebody 2011 at 236 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 power gap is worth calling out. Rated to 150 hp, the Nautica RIB 19 Widebody 2011 has a 35-hp advantage over the Nautica RIB 17 Widebody 2011's 115-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 5 gal and 6 gal — so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Nautica RIB 19 Widebody 2011 is rated for 16 passengers, while the Nautica RIB 17 Widebody 2011 caps at 12. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Nautica RIB 19 Widebody 2011 could be the deciding factor.
Bottom line: Choose the Nautica RIB 19 Widebody 2011 if your priority is putting more people on the water — it handles 16 passengers and at 18,7 ft it has the deck room to back that rating up comfortably. The Nautica RIB 17 Widebody 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 12 that costs less to run day-to-day.
