Both the Ebbtide 188 SE Bow Rider 2013 and the Ebbtide 188 SE Bow Rider O/B 2012 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 - Ebbtide 188 SE Bow Rider 2013 at 18,3 ft versus Ebbtide 188 SE Bow Rider O/B 2012 at 18,3 ft. Weight tells a clearer story for trailering families: the Ebbtide 188 SE Bow Rider 2013 tips the scales at 2 150 lbs - 430 lbs more than the Ebbtide 188 SE Bow Rider O/B 2012 at 1 720 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 190 hp, the Ebbtide 188 SE Bow Rider 2013 has a 40-hp advantage over the Ebbtide 188 SE Bow Rider O/B 2012's 150-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 188 SE Bow Rider O/B 2012 carries 26 gallons versus 20 gallons in the Ebbtide 188 SE Bow Rider 2013. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
Both boats are rated for 8 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.
Bottom line: Performance buyers should lean toward the Ebbtide 188 SE Bow Rider 2013 and its 190-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Ebbtide 188 SE Bow Rider O/B 2012 with its 150-hp rating is the more economical daily driver.
