When two boats share the same hull type — in this case both the Sea King 190CC 2012 and the Sea King 198B 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?
On paper these two are close siblings in the size department — Sea King 190CC 2012 at 18,7 ft versus Sea King 198B 2010 at 18,4 ft. Weight tells a clearer story for trailering families: the Sea King 190CC 2012 tips the scales at 1 875 lbs — 1 737 lbs more than the Sea King 198B 2010 at 138 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 150 hp, the Sea King 190CC 2012 has a 60-hp advantage over the Sea King 198B 2010's 90-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 190CC 2012 carries 55 gallons versus 33 gallons in the Sea King 198B 2010. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
Both boats are rated for 5 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 190CC 2012 and its 150-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Sea King 198B 2010 with its 90-hp rating is the more economical daily driver.
