When two boats share the same hull type — in this case both the Alumacraft MV 1756 AW SC 2013 and the Alumacraft Navigator 175 Tiller 2006 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 SC 2013 at 17,0 ft versus Alumacraft Navigator 175 Tiller 2006 at 17,0 ft. Weight tells a clearer story for trailering families: the Alumacraft Navigator 175 Tiller 2006 tips the scales at 1 145 lbs — 250 lbs less than the Alumacraft MV 1756 AW SC 2013 at 895 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 MV 1756 AW SC 2013 and 80 hp for the Alumacraft Navigator 175 Tiller 2006. 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 4 gal — so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The Alumacraft Navigator 175 Tiller 2006 is rated for 5 passengers, while the Alumacraft MV 1756 AW 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 Navigator 175 Tiller 2006 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Alumacraft MV 1756 AW SC 2013 comes in at 12 lbs per hp versus 14 lbs per hp for the Alumacraft Navigator 175 Tiller 2006. 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.
