When two boats share the same hull type — in this case both the Nautic Star 210 SC O/B 2011 and the Nautic Star 252 SL I/O 2011 are modified vee designs with composite 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?
Size is the most obvious dividing line here. The Nautic Star 252 SL I/O 2011 measures 25,7 feet overall (2011), giving it roughly 4,7 additional feet of deck space compared to the Nautic Star 210 SC O/B 2011 at 21,0 feet (2011). Weight tells a clearer story for trailering families: the Nautic Star 252 SL I/O 2011 tips the scales at 395 lbs — 130 lbs less than the Nautic Star 210 SC O/B 2011 at 265 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 320 hp, the Nautic Star 252 SL I/O 2011 has a 120-hp advantage over the Nautic Star 210 SC O/B 2011's 200-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 66 gal and 66 gal — so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Nautic Star 252 SL I/O 2011 is rated for 12 passengers, while the Nautic Star 210 SC O/B 2011 caps at 10. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Nautic Star 252 SL I/O 2011 could be the deciding factor.
Bottom line: Choose the Nautic Star 252 SL I/O 2011 if your priority is putting more people on the water — it handles 12 passengers and at 25,7 ft it has the deck room to back that rating up comfortably. The Nautic Star 210 SC O/B 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 10 that costs less to run day-to-day.
