Matching a modified vee Sea King 218B 2010 against a deep vee Sea King 230CC 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 218B 2010 at 21,5 ft versus Sea King 230CC 2010 at 23,0 ft. Weight tells a clearer story for trailering families: the Sea King 218B 2010 tips the scales at 168 lbs — 164 lbs more than the Sea King 230CC 2010 at 4 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 500 hp, the Sea King 230CC 2010 has a 300-hp advantage over the Sea King 218B 2010's 200-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 218B 2010 carries 54 gallons versus 14 gallons in the Sea King 230CC 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 230CC 2010 is rated for 7 passengers, while the Sea King 218B 2010 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sea King 230CC 2010 could be the deciding factor.
Bottom line: Choose the Sea King 230CC 2010 if your priority is putting more people on the water — it handles 7 passengers and at 23,0 ft it has the deck room to back that rating up comfortably. The Sea King 218B 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
