Both the Ebbtide 2440 Z-Trak SS Bow Rider 2009 and the Ebbtide 2640 Z-Trak SS Bow Rider 2011 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?

Size is the most obvious dividing line here. The Ebbtide 2640 Z-Trak SS Bow Rider 2011 measures 26,3 feet overall (2011), giving it roughly 3,2 additional feet of deck space compared to the Ebbtide 2440 Z-Trak SS Bow Rider 2009 at 23,2 feet (2009). Weight tells a clearer story for trailering families: the Ebbtide 2640 Z-Trak SS Bow Rider 2011 tips the scales at 5 200 lbs - 550 lbs less than the Ebbtide 2440 Z-Trak SS Bow Rider 2009 at 4 650 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 420 hp, the Ebbtide 2640 Z-Trak SS Bow Rider 2011 has a 45-hp advantage over the Ebbtide 2440 Z-Trak SS Bow Rider 2009's 375-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads - 70 gal and 70 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.
