When two boats share the same hull type — in this case both the Ebbtide 2240 SS Bow Rider 2008 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 24,3 additional feet of deck space compared to the Ebbtide 2240 SS Bow Rider 2008 at 2,0 feet (2008). Weight tells a clearer story for trailering families: the Ebbtide 2240 SS Bow Rider 2008 tips the scales at 3 475 lbs — 3 423 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.

The power gap is worth calling out. Rated to 430 hp, the Ebbtide 2640 Z-Trak SS Bow Rider 2013 has a 110-hp advantage over the Ebbtide 2240 SS Bow Rider 2008's 320-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Ebbtide 2240 SS Bow Rider 2008 carries 45 gallons versus 7 gallons in the Ebbtide 2640 Z-Trak SS Bow Rider 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 Ebbtide 2640 Z-Trak SS Bow Rider 2013 is rated for 13 passengers, while the Ebbtide 2240 SS Bow Rider 2008 caps at 10. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Ebbtide 2640 Z-Trak SS Bow Rider 2013 could be the deciding factor.
