When two boats share the same hull type — in this case both the Alumacraft VS170 2008 and the Alumacraft Waterfowler 16 2009 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 VS170 2008 at 17,0 ft versus Alumacraft Waterfowler 16 2009 at 16,0 ft. Weight tells a clearer story for trailering families: the Alumacraft VS170 2008 tips the scales at 852 lbs — 327 lbs more than the Alumacraft Waterfowler 16 2009 at 525 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.

The power gap is worth calling out. Rated to 70 hp, the Alumacraft VS170 2008 has a 30-hp advantage over the Alumacraft Waterfowler 16 2009's 40-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.

For family outings this is probably the sharpest distinction between the two. The Alumacraft Waterfowler 16 2009 is rated for 5 passengers, while the Alumacraft VS170 2008 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Alumacraft Waterfowler 16 2009 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Alumacraft VS170 2008 comes in at 12 lbs per hp versus 13 lbs per hp for the Alumacraft Waterfowler 16 2009. 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.
