Matching a flat Alumacraft 1648 NCS 2007 against a deep vee Alumacraft Dominator 175 CS 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 1648 NCS 2007 at 16,0 ft versus Alumacraft Dominator 175 CS 2013 at 17,8 ft.

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 150 hp, the Alumacraft Dominator 175 CS 2013 has a 115-hp advantage over the Alumacraft 1648 NCS 2007's 35-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.

If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Alumacraft Dominator 175 CS 2013 could be the deciding factor.

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.
