Matching a modified vee Starcraft Marine 170 Sport 2010 against a pontoon Starcraft Marine Stardeck 180 Fish 2012 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 — Starcraft Marine 170 Sport 2010 at 16,8 ft versus Starcraft Marine Stardeck 180 Fish 2012 at 18,8 ft.
