When two boats share the same hull type — in this case both the Crest 230SF - Stern Fish 2011 and the Crest Crest II Fish 210FC 2013 are pontoon designs with aluminum 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 — Crest 230SF - Stern Fish 2011 at 19,5 ft versus Crest Crest II Fish 210FC 2013 at 21,5 ft. Weight tells a clearer story for trailering families: the Crest 230SF - Stern Fish 2011 tips the scales at 2 455 lbs — 2 226 lbs more than the Crest Crest II Fish 210FC 2013 at 229 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.
Both boats share a closely matched power ceiling — 115 hp for the Crest 230SF - Stern Fish 2011 and 115 hp for the Crest Crest II Fish 210FC 2013. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup.
For family outings this is probably the sharpest distinction between the two. The Crest 230SF - Stern Fish 2011 is rated for 13 passengers, while the Crest Crest II Fish 210FC 2013 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Crest 230SF - Stern Fish 2011 could be the deciding factor.
Bottom line: Choose the Crest 230SF - Stern Fish 2011 if your priority is putting more people on the water — it handles 13 passengers and at 19,5 ft it has the deck room to back that rating up comfortably. The Crest Crest II Fish 210FC 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
