When two boats share the same hull type — in this case both the Alumacraft VB 1756 AW Tunnel SC 2013 and the Alumacraft VB 1860 AW Tunnel SC 2013 are tunnel 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 — Alumacraft VB 1756 AW Tunnel SC 2013 at 17,0 ft versus Alumacraft VB 1860 AW Tunnel SC 2013 at 18,0 ft. Weight tells a clearer story for trailering families: the Alumacraft VB 1756 AW Tunnel SC 2013 tips the scales at 905 lbs — 813 lbs more than the Alumacraft VB 1860 AW Tunnel SC 2013 at 92 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 — 75 hp for the Alumacraft VB 1756 AW Tunnel SC 2013 and 90 hp for the Alumacraft VB 1860 AW Tunnel SC 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. Both carry nearly identical fuel loads — 2 gal and 2 gal — so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Alumacraft VB 1860 AW Tunnel SC 2013 is rated for 5 passengers, while the Alumacraft VB 1756 AW Tunnel SC 2013 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Alumacraft VB 1860 AW Tunnel SC 2013 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Alumacraft VB 1860 AW Tunnel SC 2013 comes in at 1 lbs per hp versus 12 lbs per hp for the Alumacraft VB 1756 AW Tunnel SC 2013. The lower the ratio the more explosive the acceleration — meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.
Bottom line: Choose the Alumacraft VB 1860 AW Tunnel SC 2013 if your priority is putting more people on the water — it handles 5 passengers and at 18,0 ft it has the deck room to back that rating up comfortably. The Alumacraft VB 1756 AW Tunnel SC 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
