Matching a deep vee Sea King 230CC 2012 against a modified vee Sea King 238B 2010 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.
On paper these two are close siblings in the size department — Sea King 230CC 2012 at 23,0 ft versus Sea King 238B 2010 at 23,3 ft. At 4 lbs and 2 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.
The power gap is worth calling out. Rated to 500 hp, the Sea King 230CC 2012 has a 250-hp advantage over the Sea King 238B 2010's 250-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Sea King 238B 2010 carries 85 gallons versus 14 gallons in the Sea King 230CC 2012. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
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 Sea King 230CC 2012 and its 500-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Sea King 238B 2010 with its 250-hp rating is the more economical daily driver.
