Both the Striper 2101 Walkaround I/O 2013 and the Striper 2301 Walkaround I/O 2013 are deep-V designs, both built 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 - Striper 2101 Walkaround I/O 2013 at 21,5 ft versus Striper 2301 Walkaround I/O 2013 at 24,2 ft. At 4 034 lbs and 4 050 lbs respectively, both sit in a similar weight class - either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.
Both boats share a closely matched power ceiling - 320 hp for the Striper 2101 Walkaround I/O 2013 and 320 hp for the Striper 2301 Walkaround I/O 2013. 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 Striper 2301 Walkaround I/O 2013 carries 120 gallons versus 96 gallons in the Striper 2101 Walkaround I/O 2013. 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 Striper 2301 Walkaround I/O 2013 is rated for 10 passengers, while the Striper 2101 Walkaround I/O 2013 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Striper 2301 Walkaround I/O 2013 could be the deciding factor.
Bottom line: Choose the Striper 2301 Walkaround I/O 2013 if your priority is putting more people on the water - it handles 10 passengers and at 24,2 ft it has the deck room to back that rating up comfortably. The Striper 2101 Walkaround I/O 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 8 that costs less to run day-to-day.
