When two boats share the same hull type — in this case both the Ebbtide 2440 Z-Trak SS Bow Rider 2013 and the Ebbtide 2640 Z-Trak SS Bow Rider 2013 are deep 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?

Size is the most obvious dividing line here. The Ebbtide 2640 Z-Trak SS Bow Rider 2013 measures 26,3 feet overall (2013), giving it roughly 3,2 additional feet of deck space compared to the Ebbtide 2440 Z-Trak SS Bow Rider 2013 at 23,2 feet (2013). Weight tells a clearer story for trailering families: the Ebbtide 2440 Z-Trak SS Bow Rider 2013 tips the scales at 465 lbs — 413 lbs more than the Ebbtide 2640 Z-Trak SS Bow Rider 2013 at 52 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.

Both boats share a closely matched power ceiling — 430 hp for the Ebbtide 2440 Z-Trak SS Bow Rider 2013 and 430 hp for the Ebbtide 2640 Z-Trak SS Bow Rider 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. Both carry nearly identical fuel loads — 7 gal and 7 gal — so range won't be a tiebreaker here.

Both boats are rated for 13 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.
