The Starcraft Marine Jon 1436 2007 vs Starcraft Marine Star Step 221 I/O 2011 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.
Size is the most obvious dividing line here. The Starcraft Marine Star Step 221 I/O 2011 measures 21,6 feet overall (2011), giving it roughly 7,6 additional feet of deck space compared to the Starcraft Marine Jon 1436 2007 at 14,0 feet (2007).

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.

For family outings this is probably the sharpest distinction between the two. The Starcraft Marine Star Step 221 I/O 2011 is rated for 13 passengers, while the Starcraft Marine Jon 1436 2007 caps at 3. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Starcraft Marine Star Step 221 I/O 2011 could be the deciding factor.
Bottom line: Choose the Starcraft Marine Star Step 221 I/O 2011 if your priority is putting more people on the water — it handles 13 passengers and at 21,6 ft it has the deck room to back that rating up comfortably. The Starcraft Marine Jon 1436 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 3 that costs less to run day-to-day.
