Both the Baha Cruisers 240 WAC OB 2009 and the Baha Cruisers 257 WAC OB 2008 are modified-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 - Baha Cruisers 240 WAC OB 2009 at 24,0 ft versus Baha Cruisers 257 WAC OB 2008 at 25,0 ft. Weight tells a clearer story for trailering families: the Baha Cruisers 257 WAC OB 2008 tips the scales at 4 600 lbs - 1 100 lbs less than the Baha Cruisers 240 WAC OB 2009 at 3 500 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 250 hp, the Baha Cruisers 257 WAC OB 2008 has a 25-hp advantage over the Baha Cruisers 240 WAC OB 2009's 225-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads - 112 gal and 113 gal - so range won't be a tiebreaker here.
Both boats are rated for 7 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 Baha Cruisers 257 WAC OB 2008 and its 250-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Baha Cruisers 240 WAC OB 2009 with its 225-hp rating is the more economical daily driver.
