When two boats share the same hull type — in this case both the Sea Chaser 2100 RG 2010 and the Sea Chaser 2400 WA 2009 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 Chaser 2100 RG 2010 at 21,3 ft versus Sea Chaser 2400 WA 2009 at 24,0 ft. Weight tells a clearer story for trailering families: the Sea Chaser 2400 WA 2009 tips the scales at 3 492 lbs — 980 lbs less than the Sea Chaser 2100 RG 2010 at 2 512 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 300 hp, the Sea Chaser 2400 WA 2009 has a 75-hp advantage over the Sea Chaser 2100 RG 2010's 225-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 2400 WA 2009 carries 122 gallons versus 75 gallons in the Sea Chaser 2100 RG 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 Chaser 2400 WA 2009 is rated for 8 passengers, while the Sea Chaser 2100 RG 2010 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sea Chaser 2400 WA 2009 could be the deciding factor.
Bottom line: Choose the Sea Chaser 2400 WA 2009 if your priority is putting more people on the water — it handles 8 passengers and at 24,0 ft it has the deck room to back that rating up comfortably. The Sea Chaser 2100 RG 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.
