When two boats share the same hull type — in this case both the Striper 2101 Walk Around I/O 2008 and the Striper 2101 Walk Around O/B 2008 are modified vee designs with fiberglass 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?

On paper these two are close siblings in the size department — Striper 2101 Walk Around I/O 2008 at 21,0 ft versus Striper 2101 Walk Around O/B 2008 at 21,0 ft. Weight tells a clearer story for trailering families: the Striper 2101 Walk Around I/O 2008 tips the scales at 4 034 lbs — 579 lbs more than the Striper 2101 Walk Around O/B 2008 at 3 455 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 320 hp, the Striper 2101 Walk Around I/O 2008 has a 95-hp advantage over the Striper 2101 Walk Around O/B 2008's 225-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 105 gal and 105 gal — so range won't be a tiebreaker here.

Both boats are rated for 6 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.
