Matching a flat Alumacraft Pro 175 2011 against a tunnel Alumacraft VB 1650 AW Tunnel SC 2013 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.

On paper these two are close siblings in the size department — Alumacraft Pro 175 2011 at 17,4 ft versus Alumacraft VB 1650 AW Tunnel SC 2013 at 16,0 ft. At 1 lbs and 73 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.

The power gap is worth calling out. Rated to 90 hp, the Alumacraft Pro 175 2011 has a 30-hp advantage over the Alumacraft VB 1650 AW Tunnel SC 2013's 60-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.

Both boats are rated for 4 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

At this size, power-to-weight ratio matters more than outright horsepower. The Alumacraft Pro 175 2011 comes in at 0 lbs per hp versus 1 lbs per hp for the Alumacraft VB 1650 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.
