When two boats share the same hull type — in this case both the Alumacraft MV 1756 AW RR 2006 and the Alumacraft V-Bow 1860 AW Tunnel SC 2005 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 — Alumacraft MV 1756 AW RR 2006 at 17,0 ft versus Alumacraft V-Bow 1860 AW Tunnel SC 2005 at 18,0 ft. Weight tells a clearer story for trailering families: the Alumacraft V-Bow 1860 AW Tunnel SC 2005 tips the scales at 875 lbs — 789 lbs less than the Alumacraft MV 1756 AW RR 2006 at 86 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 Alumacraft MV 1756 AW RR 2006 and 115 hp for the Alumacraft V-Bow 1860 AW Tunnel SC 2005. 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. Fuel capacity breaks the other way: the Alumacraft MV 1756 AW RR 2006 carries 25 gallons versus 8 gallons in the Alumacraft V-Bow 1860 AW Tunnel SC 2005. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
For family outings this is probably the sharpest distinction between the two. The Alumacraft V-Bow 1860 AW Tunnel SC 2005 is rated for 6 passengers, while the Alumacraft MV 1756 AW RR 2006 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Alumacraft V-Bow 1860 AW Tunnel SC 2005 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Alumacraft MV 1756 AW RR 2006 comes in at 1 lbs per hp versus 8 lbs per hp for the Alumacraft V-Bow 1860 AW Tunnel SC 2005. 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 V-Bow 1860 AW Tunnel SC 2005 if your priority is putting more people on the water — it handles 6 passengers and at 18,0 ft it has the deck room to back that rating up comfortably. The Alumacraft MV 1756 AW RR 2006 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
