The Starcraft Marine Fishmaster 196 2011 is a modified-V design and the Starcraft Marine Stardeck 206 Cruise 2012 is a pontoon design, so you're likely deciding between two noticeably 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 Fishmaster 196 2011 at 19,8 ft versus Starcraft Marine Stardeck 206 Cruise 2012 at 20,8 ft. Weight tells a clearer story for trailering families: the Starcraft Marine Stardeck 206 Cruise 2012 tips the scales at 1 850 lbs - 420 lbs less than the Starcraft Marine Fishmaster 196 2011 at 1 430 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 200 hp, the Starcraft Marine Fishmaster 196 2011 has a 85-hp advantage over the Starcraft Marine Stardeck 206 Cruise 2012's 115-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Starcraft Marine Fishmaster 196 2011 carries 52 gallons versus 30 gallons in the Starcraft Marine Stardeck 206 Cruise 2012. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
For family outings this is probably the sharpest distinction between the two. The Starcraft Marine Stardeck 206 Cruise 2012 is rated for 10 passengers, while the Starcraft Marine Fishmaster 196 2011 caps at 9. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Starcraft Marine Stardeck 206 Cruise 2012 could be the deciding factor.
Bottom line: Choose the Starcraft Marine Stardeck 206 Cruise 2012 if your priority is putting more people on the water - it handles 10 passengers and at 20,8 ft it has the deck room to back that rating up comfortably. The Starcraft Marine Fishmaster 196 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 9 that costs less to run day-to-day.
