Both the Starcraft Marine 2100 2010 and the Starcraft Marine Star Step 190 IO 2008 are modified-V designs, the first built in aluminium and the second in fibreglass, 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 2100 2010 at 20,8 ft versus Starcraft Marine Star Step 190 IO 2008 at 21,0 ft. Weight tells a clearer story for trailering families: the Starcraft Marine Star Step 190 IO 2008 tips the scales at 2 250 lbs - 535 lbs less than the Starcraft Marine 2100 2010 at 1 715 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 250 hp, the Starcraft Marine 2100 2010 has a 246-hp advantage over the Starcraft Marine Star Step 190 IO 2008's 4-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads - 52 gal and 51 gal - so range won't be a tiebreaker here.

Both boats are rated for 10 passengers - a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
