Both the Starcraft Marine Coastal 2009 OB 2013 and the Starcraft Marine Superfisherman 176 2012 are modified-V designs, the first built in fibreglass and the second in aluminium, so the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?
On paper these two are close siblings in the size department - Starcraft Marine Coastal 2009 OB 2013 at 20,3 ft versus Starcraft Marine Superfisherman 176 2012 at 17,7 ft. Weight tells a clearer story for trailering families: the Starcraft Marine Coastal 2009 OB 2013 tips the scales at 2 405 lbs - 1 157 lbs more than the Starcraft Marine Superfisherman 176 2012 at 1 248 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.
Both boats share a closely matched power ceiling - 200 hp for the Starcraft Marine Coastal 2009 OB 2013 and 200 hp for the Starcraft Marine Superfisherman 176 2012. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Fuel capacity breaks the other way: the Starcraft Marine Coastal 2009 OB 2013 carries 51 gallons versus 32 gallons in the Starcraft Marine Superfisherman 176 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 Coastal 2009 OB 2013 is rated for 12 passengers, while the Starcraft Marine Superfisherman 176 2012 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Starcraft Marine Coastal 2009 OB 2013 could be the deciding factor.
Bottom line: Choose the Starcraft Marine Coastal 2009 OB 2013 if your priority is putting more people on the water - it handles 12 passengers and at 20,3 ft it has the deck room to back that rating up comfortably. The Starcraft Marine Superfisherman 176 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 8 that costs less to run day-to-day.
