When two boats share the same hull type — in this case both the Ebbtide 2640 Z-Trak SS Bow Rider 2010 and the Ebbtide 2660 Z-Trak SS DC FC 2008 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?
On paper these two are close siblings in the size department — Ebbtide 2640 Z-Trak SS Bow Rider 2010 at 26,3 ft versus Ebbtide 2660 Z-Trak SS DC FC 2008 at 26,0 ft. At 52 lbs and 52 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 — 420 hp for the Ebbtide 2640 Z-Trak SS Bow Rider 2010 and 425 hp for the Ebbtide 2660 Z-Trak SS DC FC 2008. 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.
For family outings this is probably the sharpest distinction between the two. The Ebbtide 2660 Z-Trak SS DC FC 2008 is rated for 14 passengers, while the Ebbtide 2640 Z-Trak SS Bow Rider 2010 caps at 13. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Ebbtide 2660 Z-Trak SS DC FC 2008 could be the deciding factor.
Bottom line: Choose the Ebbtide 2660 Z-Trak SS DC FC 2008 if your priority is putting more people on the water — it handles 14 passengers and at 26,0 ft it has the deck room to back that rating up comfortably. The Ebbtide 2640 Z-Trak SS Bow Rider 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 13 that costs less to run day-to-day.
