When two boats share the same hull type — in this case both the Sea King 190CC 2010 and the Sea King 238B 2010 are modified 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 Sea King 238B 2010 measures 23,3 feet overall (2010), giving it roughly 4,7 additional feet of deck space compared to the Sea King 190CC 2010 at 18,7 feet (2010). Weight tells a clearer story for trailering families: the Sea King 190CC 2010 tips the scales at 1 875 lbs — 1 873 lbs more than the Sea King 238B 2010 at 2 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 Sea King 238B 2010 has a 100-hp advantage over the Sea King 190CC 2010'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 Sea King 238B 2010 carries 85 gallons versus 55 gallons in the Sea King 190CC 2010. 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 Sea King 238B 2010 is rated for 7 passengers, while the Sea King 190CC 2010 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sea King 238B 2010 could be the deciding factor.
Bottom line: Choose the Sea King 238B 2010 if your priority is putting more people on the water — it handles 7 passengers and at 23,3 ft it has the deck room to back that rating up comfortably. The Sea King 190CC 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
