When two boats share the same hull type — in this case both the Starcraft Marine 1620 Camp Side 2008 and the Starcraft Marine Star Step 220 I/O 2013 are modified vee designs with aluminum construction — 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?

Size is the most obvious dividing line here. The Starcraft Marine Star Step 220 I/O 2013 measures 21,9 feet overall (2013), giving it roughly 5,9 additional feet of deck space compared to the Starcraft Marine 1620 Camp Side 2008 at 16,0 feet (2008). Weight tells a clearer story for trailering families: the Starcraft Marine Star Step 220 I/O 2013 tips the scales at 2 325 lbs — 2 268 lbs less than the Starcraft Marine 1620 Camp Side 2008 at 57 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 270 hp, the Starcraft Marine Star Step 220 I/O 2013 has a 230-hp advantage over the Starcraft Marine 1620 Camp Side 2008's 40-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.

For family outings this is probably the sharpest distinction between the two. The Starcraft Marine Star Step 220 I/O 2013 is rated for 12 passengers, while the Starcraft Marine 1620 Camp Side 2008 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Starcraft Marine Star Step 220 I/O 2013 could be the deciding factor.
