When two boats share the same hull type — in this case both the Stabicraft 1650 Fisher 2013 and the Stabicraft 1850 Fisher 2012 are modified vee 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 — Stabicraft 1650 Fisher 2013 at 16,5 ft versus Stabicraft 1850 Fisher 2012 at 18,5 ft. Weight tells a clearer story for trailering families: the Stabicraft 1650 Fisher 2013 tips the scales at 2 525 lbs — 431 lbs more than the Stabicraft 1850 Fisher 2012 at 2 094 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 — 100 hp for the Stabicraft 1650 Fisher 2013 and 115 hp for the Stabicraft 1850 Fisher 2012. 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 Stabicraft 1850 Fisher 2012 is rated for 6 passengers, while the Stabicraft 1650 Fisher 2013 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Stabicraft 1850 Fisher 2012 could be the deciding factor.
Bottom line: Choose the Stabicraft 1850 Fisher 2012 if your priority is putting more people on the water — it handles 6 passengers and at 18,5 ft it has the deck room to back that rating up comfortably. The Stabicraft 1650 Fisher 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
