Matching a deep vee Sea Chaser 175 RG 2012 against a pontoon Sea Chaser 2100 WA 2009 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.
Size is the most obvious dividing line here. The Sea Chaser 2100 WA 2009 measures 21,0 feet overall (2009), giving it roughly 3,6 additional feet of deck space compared to the Sea Chaser 175 RG 2012 at 17,4 feet (2012). Weight tells a clearer story for trailering families: the Sea Chaser 2100 WA 2009 tips the scales at 293 lbs — 162 lbs less than the Sea Chaser 175 RG 2012 at 131 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 WA 2009 has a 125-hp advantage over the Sea Chaser 175 RG 2012's 100-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 WA 2009 carries 75 gallons versus 25 gallons in the Sea Chaser 175 RG 2012. 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 Chaser 2100 WA 2009 is rated for 7 passengers, while the Sea Chaser 175 RG 2012 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sea Chaser 2100 WA 2009 could be the deciding factor.
Bottom line: Choose the Sea Chaser 2100 WA 2009 if your priority is putting more people on the water — it handles 7 passengers and at 21,0 ft it has the deck room to back that rating up comfortably. The Sea Chaser 175 RG 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
