Matching a deep vee Alumacraft Competitior 185 Tiller 2011 against a modified vee Alumacraft Navigator 175 Tiller 2007 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 Competitior 185 Tiller 2011 at 18,7 ft versus Alumacraft Navigator 175 Tiller 2007 at 17,0 ft.

On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
