Matching a modified vee Sea Chaser 1900 CC 2010 against a deep vee Sea Chaser 2100 RG 2012 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 Chaser 1900 CC 2010 at 18,7 ft versus Sea Chaser 2100 RG 2012 at 21,3 ft. Weight tells a clearer story for trailering families: the Sea Chaser 2100 RG 2012 tips the scales at 2 512 lbs — 2 346 lbs less than the Sea Chaser 1900 CC 2010 at 166 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 225 hp, the Sea Chaser 2100 RG 2012 has a 75-hp advantage over the Sea Chaser 1900 CC 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 Chaser 2100 RG 2012 carries 75 gallons versus 52 gallons in the Sea Chaser 1900 CC 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 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: The Sea Chaser 2100 RG 2012 at 21,3 ft is the right call if deck space, comfort, and entertaining are top of your list. The Sea Chaser 1900 CC 2010 at 18,7 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.
